  INTRODUCTION: The clinical and genetic spectrum of inherited Fanconi renotubular syndrome (FRTS) remains incompletely characterized, and the role of recently recognized genes such as GATM has not been systematically assessed. METHODS: This retrospective study included 20 families with FRTS (14 pediatric and 6 adult index cases) who underwent targeted panel sequencing between 2016 and 2024. The variant spectrum and clinical characteristics were evaluated. Previously reported cases were reviewed to elucidate the phenotypic spectrum and renal prognosis in patients with GATM variants. RESULTS: Pathogenic variants were identified in 13 of 20 index cases (65%; 4 pediatric, 9 adult cases). Disease-causing genes detected included GATM (n = 7), CLCN5 (n = 2), HNF4A (n = 1), BCS1L (n = 1), CTNS (n = 1), and EHHADH (n = 1). Notably, 4 of the 7 GATM variants were completely novel, and 2 others were first reported by our group. The review, incorporating our cases, revealed that patients with GATM variants frequently exhibited incomplete FRTS, expanding the known clinical spectrum. Kidney function exhibited progressive decline, with combined analyses of our cohort and published cases indicating a median kidney survival age of 51.9 years, establishing GATM-associated FRTS as progressive tubulopathy. CONCLUSION: Over half of the patients with primary FRTS displayed detectable monogenic etiologies, with GATM variants being unexpectedly prevalent. Our findings provide new insights into the genetic and clinical spectrum of FRTS with GATM variants, highlighting its under-recognition, phenotypic variability, and progressive kidney dysfunction. GATM variants should be considered in patients with incomplete proximal tubular abnormalities or unexplained chronic kidney disease (CKD).

• A novel splice site variant in TIMM8A induced abnormal mRNA splicing resulting in Mohr-Tranebjaerg syndrome.

  Hiroaki Hanafusa, Yusuke Ishida, Ryosuke Bo, Masahiro Nishiyama, Kandai Nozu, Hiroaki Nagase, Hiroyuki Awano

  BACKGROUND: Mohr-Tranebjaerg syndrome (MTS) is an X-linked recessive neurodegenerative disorder caused by pathogenic variants in TIMM8A. Of the 39 previously reported disease-causing variants in the TIMM8A, five are splice site variants; however, none of these variants have been evaluated by transcript analysis. METHODS: We performed panel-based targeted exome analysis in a Japanese boy with sensorineural hearing loss and rapidly progressive dystonia. To assess the effect of the identified splice donor site variant, transcript analysis was performed using RNA derived from peripheral blood. RESULT: A novel hemizygous splice donor site variant in TIMM8A (NM_004085.4:c.132+5G>A) was identified. Transcript analysis revealed three aberrant transcripts: two transcripts with partial intron 1 inclusion of 606 bp or 492 bp (INS606bp and INS492bp) and one transcript with a 60 bp partial deletion of exon 1 (Δ60bp), with no detectable normal transcript. Both INS606bp and INS492bp transcripts contain premature stop codons due to the inserted intronic sequences, leading to the loss of 53 amino acids, whereas the Δ60bp transcript leads to the loss of 20 amino acids. All aberrant transcripts lacked part of the Tim10/DDP family zinc finger domain, which is essential for TIM8A function. CONCLUSION: This study provides the first transcript analysis elucidating the pathogenic mechanism of a splice donor site variant in TIMM8A. The findings suggest that splice donor site variants may share a common disease mechanism involving the production of functionally defective TIM8A protein.

  Yoshitaka Asagai, Yu Tanaka, Hiroaki Hanafusa, China Nagano, Tomoko Horinouchi, Shingo Ishimori, Hiroshi Kaito, Kazumoto Iijima, Kandai Nozu, Naoya Morisada

  BACKGROUND: The Spalt-like transcription factor 1 (SALL1) gene is essential for kidney development. Pathogenic SALL1 variants cause Townes-Brocks syndrome 1 (TBS1), which typically presents with imperforate anus, dysplastic ears, and digital anomalies. However, clinical features vary widely. Some patients present only with dysplastic ears and hearing loss (HL) or with congenital anomalies of the kidney and urinary tract (CAKUT), resembling branchio-oto-renal syndrome (BORS), a presentation referred to as Townes-Brocks branchio-oto-renal-like (TBS BOR-like) syndrome. In this study, we aimed to describe the clinical characteristics of patients with SALL1-related disorders in the Japanese population. METHODS: We analyzed phenotypes of a nationwide cohort comprising 1108 families with chronic kidney disease (CKD) or mild urinary anomalies, using genetic testing conducted from 2010 to 2024. RESULTS: We identified SALL1 variants in 14 families (20 individuals): seven frameshift, four nonsense, one missense, one exon 2 deletion, and one whole-gene deletion. Ten variants were novel. The median age at diagnosis was 16 years (male:female = 13:7). Dysplastic ears were observed in 45%, HL in 40%, digital anomalies in 40%, and anorectal malformations in 25%. Based on clinical features, eight individuals were diagnosed with TBS1, four with TBS BOR-like syndrome, and seven with non-syndromic CAKUT. One case lacked detailed clinical data. Most variants were truncating and located in exon 2. CONCLUSIONS: SALL1-related disorders exhibit broad phenotypic variability. Some cases present with atypical features overlapping with TBS BOR-like syndrome or isolated CAKUT, rather than with typical TBS1. These findings enhance the understanding and diagnosis of SALL1-related disorders.

• The first case of Al-Raqad syndrome in Japan is associated with a homozygous DCPS exonic variant resulting in aberrant splicing.

  BACKGROUND: Cases of unexplained neurodevelopmental disorder (NDD) are often accompanied by multiple congenital anomalies. With recent advances in genetic analysis technology, whole-exome sequencing (WES) has become a powerful diagnostic tool for unexplained NDD patients, but variants of unknown significance are sometimes detected in them. METHODS: WES identified a variant in a 2-year-old boy with NDD associated with multiple congenital anomalies who had no abnormal findings in G-banding and array comparative genomic hybridization (array CGH). mRNA analysis was performed on the variant using the patient's peripheral blood leukocytes following in silico analysis to confirm its effect on splicing. RESULTS: WES revealed a novel homozygous single base substituting variant of unknown significance (VUS), which was carried heterozygously by the patient's parents (DCPS, NM_014026.6: c.200A>G, p.(Lys67Arg)). In silico analysis predicted that this variant may cause aberrant splicing, and mRNA analysis revealed a 48-bp deletion from the 3' end of exon 1. Biallelic variants of DCPS are known to cause Al-Raqad syndrome, a quite rare disorder which presents NDD with multiple malformations. This disease has been reported in only eight individuals from five Middle Eastern or Caucasian families but never in the Japanese but the symptoms of the present case were similar to reported cases of this syndrome. DISCUSSION: We successfully diagnosed a case of unexplained NDD as Al-Raqad syndrome by WES along with mRNA analysis. Single base substitution with judged VUS can be pathogenic by causing aberrant splicing and, therefore, in silico analysis and subsequent RNA sequence are necessary to prove its pathogenicity.

• Total Intramuscular Fat Fraction of Thigh Muscles as a Predictor of Nusinersen Efficacy in Pediatric SMA Type II and III

  Kiiko Iketani, Hiroyuki Awano, Hiromi Hashimura, Shoko Sonehara, Hiroaki Hanafusa, Yoshinori Nambu, Hisahide Nishio, Kandai Nozu, Ryosuke Bo

  Background/Objectives: Nusinersen is a disease-modifying drug for spinal muscular atrophy (SMA) that improves motor function. However, its effects on the skeletal muscles remain unclear. This study aimed to assess the intramuscular fat fraction in patients with SMA types II and III using muscle magnetic resonance imaging (MRI) and to explore the relationship between muscle tissue, lipid metabolism, and motor function during nusinersen treatment. Methods: This study included seven pediatric patients with SMA types II and III who received nusinersen treatment. Muscle MRIs were performed at three time points. Images of the central thigh were used to measure the cross-sectional area (CSA) and muscle fat area, and the intramuscular fat fraction (IMFF) was calculated. The thigh muscles were categorized into three groups: quadriceps, adductor, and hamstrings. Results: The median (range) of total IMFF for SMA type II and III at T-0, T-2, and T-4 were 18.5 (12.6-48.4), 24.4 (10.1-61.4), and 39.0 (30.0-68.6) % and increased over time. In five patients whose motor function was evaluated, a moderate negative correlation was observed between the changes in the Hammersmith Functional Motor Score Expanded (HSFME) and IMFF (r = -0.51). No significant changes in serum triglyceride or total cholesterol levels were observed during treatment. Conclusions: An increase in IMFF was associated with a decline in motor function. The baseline IMFF score was related to improvements in motor function scores, suggesting that the IMFF of the thigh muscle may serve as a novel, objective, and quantitative skeletal muscle-related biomarker for predicting the effects of nusinersen on muscle tissue.

  The coronavirus disease 2019 (COVID-19) pandemic has affected people worldwide, and pediatric patients with underlying diseases are at high risk of developing severe COVID-19. However, there are limited reports on the clinical impact of COVID-19, especially in patients with underlying neuromuscular diseases (NMD) and inborn errors of metabolism (IEM). This study aimed to investigate the incidence and clinical presentation of COVID-19 in patients with NMD and IEM. This was a single-center, cross-sectional study of patients with NMD and IEM in Japan for 2 years, from April 1, 2020 to March 31, 2022. Among 255 participants with a median age of 14 (range: 0-50) years, 192 (75%) and 63 (25%) had NMD and IEM, respectively. Among 255 patients, 8 (5 NMD and 3 IEM) were positive for the anti-severe acute respiratory syndrome coronavirus 2 nucleocapsid antibody, and the incidence was considered 3%. All positive patients had mild or asymptomatic COVID-19. None of the patients exhibited moderate or severe symptoms. In conclusion, this study revealed that the incidence of COVID-19 was low, and mild or subclinical infection was common even in patients with NMD and IEM, who may be at a higher risk of severe COVID-19.

  Hiroaki Hanafusa, Hiroshi Yamaguchi, Naoya Morisada, Ming Juan Ye, Shizuka Oikawa, Shoichi Tokumoto, Masahiro Nishiyama, Kandai Nozu, Hiroaki Nagase

  PURPOSE: Status epilepticus associated with fever (SEF) is often encountered in pediatric emergency departments, and some patients develop neurological emergencies, such as acute encephalopathy (AE). Although numerous genetic variants of developmental and epileptic encephalopathy (DEE) have been reported, the frequency of these disease-associated variants of SEF is unknown. The first aim of this study was to investigate the associated genetic variants of SEF. The second aim was to compare the variations in genes between SEF and DEE. METHOD: This retrospective, clinical observational study included patients with SEF or DEE who visited Kobe University Hospital or Kobe University affiliated hospitals and provided consent for a genetic diagnosis of SEF or DEE between January 1, 2021, and December 31, 2022. FINDING: Fifteen patients with SEF and 27 patients with DEE consented to a genetic diagnosis and were included in the study. The detection rate of genetic variants was lower in patients with SEF (26.7%) than in those with DEE (63.0%), although there is no statistically significant difference (p = 0.05, Fisher's exact test). Analysis of patients with DEE revealed a wide variety of causative genes for DEE (16 different genes), whereas in SEF cases, only SCN1A variants were detected. CONCLUSION: Our study is the first to clarify the detection rates of different genetic variants in SEF. Patients with SEF may have less genetic involvement in the onset of epileptic seizures, compared to those with DEE.

• End-stage ADPKD with a low-frequency PKD1 mosaic variant accelerated by chemoradiotherapy.

  Hiroaki Hanafusa, Hiroshi Yamaguchi, Naoya Morisada, Ming Juan Ye, Riki Matsumoto, Hiroaki Nagase, Kandai Nozu

  Autosomal dominant polycystic kidney disease (ADPKD) is commonly caused by PKD1, and mosaic PKD1 variants result in milder phenotypes. We present the case of a 32 year-old male with chronic active Epstein-Barr virus who underwent bone marrow transplantation with chemoradiotherapy at age 9. Despite a low-frequency mosaic splicing PKD1 variant, he developed severe renal cysts and end-stage renal disease in his 30 s. This case highlights how environmental factors may contribute to the genetic predisposition to ADPKD.

  Recently, heterozygous loss-of-function NFKB1 variants were identified as the primary cause of common variable immunodeficiency (CVID) in the European population. However, pathogenic NFKB1 variants have never been reported in the Japanese population. We present a 29-year-old Japanese woman with CVID. A novel variant, c.136 C > T, p.(Gln46*), was identified in NFKB1. Her mother and daughter carried the same variant, demonstrating the first Japanese pedigree with an NFKB1 pathogenic variant.

  Abstract Lysinuric protein intolerance (LPI), caused by pathogenic variants of SLC7A7, is characterized by protein aversion, failure to thrive, hyperammonemia, and hepatomegaly. Recent studies have reported that LPI can cause multiple organ dysfunctions, including kidney disease, autoimmune deficiency, pulmonary alveolar proteinosis, and osteoporosis. We report the case of a 47‐year‐old Japanese woman who was initially diagnosed with renal tubular acidosis (RTA), Fanconi syndrome, and rickets. At the age of 3 years, she demonstrated a failure to thrive. Urinary amino acid analysis revealed elevated lysine and arginine levels, which were masked by pan‐amino aciduria. She was subsequently diagnosed with rickets at 5 years of age and RTA/Fanconi syndrome at 15 years of age. She was continuously treated with supplementation of vitamin D3, phosphate, and bicarbonate. A renal biopsy at 18 years of age demonstrated diffuse proximal and distal tubular damage with endocytosis‐lysosome pathway abnormalities. Distinctive symptoms of LPI, such as protein aversion and postprandial hyperammonemia were not observed throughout the patient's clinical course. The patient underwent a panel‐based comprehensive genetic testing and was diagnosed with LPI. As the complications of LPI involve many organs, patients lacking distinctive symptoms may develop various diseases, including RTA/Fanconi syndrome. Our case indicates that proximal and distal tubular damages are notable findings in patients with LPI. The possibility of LPI should be carefully considered in the management of RTA/Fanconi syndrome and/or incomprehensible pathological tubular damage, even in the absence of distinctive symptoms; furthermore, a comprehensive genetic analysis is useful for diagnosing LPI.

  INTRODUCTION: Variants in the galactosidase alpha (GLA) gene cause Fabry disease (FD), an X-linked lysosomal storage disorder caused by α-galactosidase A (α-GAL) deficiency. Recently, disease-modifying therapies have been developed, and simple diagnostic biomarkers for FD are required to initiate these therapies in the early stages of the disease. Detection of urinary mulberry bodies and cells (MBs/MCs) is beneficial for diagnosing FD. However, few studies have evaluated the diagnostic accuracy of urinary MBs/MCs in FD. Herein, we retrospectively evaluated the diagnostic ability of urinary MBs/MCs for FD. METHODS: We analyzed the medical records of 189 consecutive patients (125 males and 64 females) who underwent MBs/MCs testing. Out of these, two female patients had already been diagnosed with FD at the time of testing, and the remaining 187 patients were suspected of having FD and underwent both GLA gene sequencing and/or α-GalA enzymatic testing. RESULTS: Genetic testing did not confirm the diagnosis in 50 females (26.5%); hence, they were excluded from the evaluation. Two patients were previously diagnosed with FD, and sixteen were newly diagnosed. Among these 18 patients, 15, including two who had already developed HCM at diagnosis, remained undiagnosed until targeted genetic screening of at-risk family members of patients with FD was performed. The accuracy of urinary MBs/MCs testing exhibited a sensitivity of 0.944, specificity of 1, positive predictive value of 1, and negative predictive value of 0.992. CONCLUSIONS: MBs/MCs testing is highly accurate in diagnosing FD and should be considered during the initial evaluation prior to genetic testing, particularly in female patients.

  OBJECTIVE: Hemorrhagic shock and encephalopathy syndrome (HSES) is a serious condition that requires intensive care and is associated with a high mortality rate. However, its pathogenesis remains unclear. In the present study, a genetic analysis was performed to determine the genetic background of patients with clinically suspected Dravet syndrome (DS) who developed HSES. METHODS: Whole exome sequencing was performed, followed by minigene analysis of the intron variant detected by whole exome sequencing to confirm its effect on splicing. RESULTS: Whole exome sequencing revealed a novel 21-bp deletion in intron 3 of SCN1A NM_001165963.4 (NC_000002.11:g.166073675_166073695del). This deletion was not found in the patient's parents and was proven to be de novo. Minigene analysis revealed an aberrant mRNA lacking 40 and 106 bp from the 5' end of exon 4 of SCN1A. Therefore, we diagnosed this case as DS due to the deletion in intron 3 of SCN1A. CONCLUSIONS: We report a case of DS with HSES caused by a 21-bp deletion in the intron of SCN1A that was confirmed by minigene analysis. The present case met Levin's criteria for HSES and the splicing analysis of SCN1A is an important finding. This study has important implications for understanding HSES pathogenesis.

• Germ-cell-specific transcriptome analysis illuminates the chromatin and ubiquitin pathway in autism spectrum disorders.

  Sawako Furukawa, Jun Nomura, Hiroaki Hanafusa, Hiroko Maegawa, Toru Takumi

  Accumulating epidemiological studies have suggested a positive association between advanced paternal age at conception and the increased risk of neurodevelopmental outcomes such as autism spectrum disorder (ASD) in their children. Recent biological studies using human sperm have identified increased de novo mutations in aged fathers, and hyper- or hypomethylation has been identified in the sperm from aged rodents. Dysregulation of DNA methylation in sperm may explain the transgenerational effects on the pathogenesis of ASD. However, compared to these epigenetic changes in the sperm of aged males, the effects of inherited predisposition from germ cells are largely unknown. Here, we use single-cell transcriptome data sets from 13 cell lines, including 12 ASD-associated CNVs models and control, that are performed neural differentiation from mouse embryonic stem cells. This study performed comprehensive bioinformatic analyses such as gene ontology (GO), network, pathway, and upstream regulator analyses. Through these analyses, we identify several susceptible pathways, such as chromatin and ubiquitin, in addition to translational and oxidative phosphorylation. Our results suggest that dysregulation of epigenetic chromosome remodeling and ubiquitin-proteasome pathway in the germ cell is a possible modulator for subsequent differentiated cells, sperm, and egg, as a risk factor for the neurodevelopmental disorder.

• Impact after the Change from Voluntary to Universal Oral Rotavirus Vaccination on Consecutive Emergency Department Visits for Acute Gastroenteritis among Children in Kobe City, Japan (2016-2022).

  Hiroshi Yamaguchi, Kandai Nozu, Hiroaki Hanafusa, Yoshinori Nambu, Takumi Kido, Atsushi Kondo, Akihiro Tamura, Hiroyuki Awano, Ichiro Morioka, Hiroaki Nagase, Akihito Ishida

  Rotavirus (RV) is the leading cause of acute gastroenteritis (AGE), particularly in infants. In 2006, the high efficacy of oral RV vaccines (RVVs, RotarixTM and RotaTeqTM) was demonstrated. Voluntary RVV started in Japan in 2011, and in October 2020 were launched as universal oral RVVs in Japan. However, the impact of changes from voluntary to universal RVVs has not been studied in a primary emergency medical center in Japan. We investigated changes in the number of pediatric patients with AGE after introducing universal RVVs in our center. A clinical database of consecutive patients aged <16 who presented to Kobe Children’s Primary Emergency Medical Center between 1 April 2016 and 30 June 2022 was reviewed. After implementing universal RVVs, fewer children presented with RV-associated AGE (the reduction of proportion of the patients in 2022 was −61.7% (all ages), −57.9% (<1 years), −67.8% (1−<3 years), and −61.4% (3−<5 years) compared to 2019). A similar decrease in those of age who were not covered by the universal RVV was observed. There was a significant decline in the number of patients with AGE during the RV season who presented to the emergency department after implementing universal RVVs.

• Influence of UGT1A1 Genetic Variants on Free Bilirubin Levels in Japanese Newborns: A Preliminary Study.

  Hiroaki Hanafusa, Shinya Abe, Shohei Ohyama, Yuki Kyono, Takumi Kido, Ruka Nakasone, Mariko Ashina, Kenji Tanimura, Kandai Nozu, Kazumichi Fujioka

  BACKGROUND: Free bilirubin (Bf) is a better marker than total serum bilirubin (TSB) for predicting bilirubin encephalopathy (BE). To date, two UGT1A1 genetic variants (rs4148323 and rs3064744) have been associated with neonatal hyperbilirubinemia; however, the direct association between UGT1A1 variants and Bf levels in newborns has not been elucidated. METHODS: We retrospectively analyzed the clinical data of 484 infants, including the genotype data of two UGT1A1 genetic variants. We divided the infants into a high Bf group (Bf ≥ 1.0 µg/dL, n = 77) and a non-high Bf group (Bf < 1.0 µg/dL, n = 407), based on the peak Bf values. Logistic regression analysis was performed to calculate the odds ratios (ORs) for each variant allele compared to wild-type alleles. RESULTS: The frequencies of the A allele in rs4148323 and (TA)7 allele in rs3064744 in the high Bf group (29% and 4%, respectively) were significantly different from those in the non-high Bf group (16% and 12%, respectively). In logistic regression analysis, for rs4148323, the A allele was significantly associated with an increased risk of hyper-free bilirubinemia over the G allele (adjusted OR: 1.80, 95% confidence interval [CI]: 1.19-2.72, p < 0.01). However, for rs3064744, the (TA)7 allele was significantly associated with a decreased risk of hyper-free bilirubinemia over the (TA)6 allele (adjusted OR: 0.42, 95% CI: 0.18-0.95, p = 0.04). CONCLUSIONS: This study is the first to show that the A allele in rs4148323 is a risk factor and that the (TA)7 allele in rs3064744 is a protective factor for developing hyper-free bilirubinemia in Japanese newborns.

• Heterozygous missense variant in TRPC6 in a boy with rapidly progressive infantile nephrotic syndrome associated with diffuse mesangial sclerosis.

  Transient receptor potential channel C6 encoded by TRPC6 is involved in slit diaphragm formation in podocytes, and abnormalities of the TRPC6 protein cause various glomerular diseases. The first identified pathogenic variant of TRPC6 was found to cause steroid-resistant nephrotic syndrome that typically developed in adulthood and then slowly led to end-stage renal disease, along with a renal pathology of focal segmental glomerulosclerosis. Here, we report a patient with rapidly progressing infantile nephrotic syndrome and a heterozygous missense TRPC6 variant. The patient, a 2-year-old Japanese boy, developed steroid-resistant nephrotic syndrome at age 11 months. His renal function deteriorated rapidly, and peritoneal dialysis was introduced at age 1 year and 6 months. His renal pathology, obtained at age 1 year and 1 month, was consistent with diffuse mesangial sclerosis (DMS). Clinical exome analysis and custom panel analysis for hereditary renal diseases revealed a reported heterozygous missense variant in TRPC6 (NM_004621.5:c.523C > T:p.Arg175Trp). This is the first report of a patient with a TRPC6-related renal disorder associated with DMS.

• A Japanese boy with NAA10-related syndrome and hypertrophic cardiomyopathy.

  Ayumi Shishido, Naoya Morisada, Kenta Tominaga, Hiroyasu Uemura, Akiko Haruna, Hiroaki Hanafusa, Kandai Nozu, Kazumoto Iijima

  NAA10-related syndrome is an extremely rare X-chromosomal disorder, the symptoms of which include intellectual disability (ID), ocular anomalies, or congenital heart diseases, such as hypertrophic cardiomyopathy (HCM). Here, we describe a 4-year-old Japanese male patient who exhibited mild ID, HCM, and specific facial features. A hemizygous mutation (NM_003491.3: c.455_458del, p. Thr152Argfs*6) in exon 7 of NAA10 was detected. We recommend that patients undergo precise medical follow-up considering the characteristics of NAA10-related syndrome.

• A girl with CLOVES syndrome with a recurrent PIK3CA somatic mutation and pancreatic steatosis.

  Hiroaki Hanafusa, Naoya Morisada, Tadashi Nomura, Daisuke Kobayashi, Yoshinobu Akasaka, Ming Juan Ye, Kandai Nozu, Noriyuki Nishimura, Kazumoto Iijima, Hideto Nakao

  CLOVES syndrome is characterized by congenital lipomatous overgrowth, vascular malformation, epidermal nevi, and scoliosis/spinal malformation. It is caused by somatic mosaicism of gain-of-function variants of PIK3CA. Here, we describe a novel case of a 5-year-old Japanese girl with CLOVES and concurrent pancreatic steatosis. She had a recurrent somatic mutation in PIK3CA (NM_006218.3: c.1357G>A, p.Glu453Lys), elevated HbA1c levels, and pancreatic steatosis. This case indicates that pancreatic screening is critical for PIK3CA-related disorders.

  The 20q11.2 microdeletion is a rare chromosomal aberration characterized by intellectual disability (ID), motor developmental delay, neonatal feeding problems, and facial dysmorphism. Here, a 2-year- and 6-month-old Japanese girl with a 1.2 Mb microdeletion of 20q11.2 showed ID, motor developmental delay, and distinctive facial features without feeding problems. The deleted region was identified by array-based comparative genomic hybridization and is the smallest reported for a 20q11.2 microdeletion.
