      Congenital hypomyelinating disorders are a heterogeneous group of inherited leukoencephalopathies characterized by abnormal myelin formation. We have recently reported a hypomyelinating syndrome characterized by diffuse cerebral hypomyelination with cerebellar atrophy and hypoplasia of the corpus callosum (HCAHC). We performed whole-exome sequencing of three unrelated individuals with HCAHC and identified compound heterozygous mutations in POLR3B in two individuals. The mutations include ...

      OBJECTIVE: RNF213 was recently reported as a susceptibility gene for moyamoya disease (MMD). Our aim was to clarify the correlation between the RNF213 genotype and MMD phenotype.

      METHODS: The entire coding region of the RNF213 gene was sequenced in 204 patients with MMD, and corresponding variants were checked in 62 pairs of parents, 13 mothers and 4 fathers of the patients, and 283 normal controls. Clinical information was collected. Genotype-phenotype correlations were statistically ...

      PURPOSE: Ohtahara syndrome (OS) is one of the most severe and earliest forms of epilepsy. STXBP1 and ARX mutations have been reported in patients with OS. In this study, we aimed to identify new genes involved in OS by copy number analysis and whole exome sequencing.

      METHODS: Copy number analysis and whole exome sequencing were performed in 34 and 12 patients with OS, respectively. Fluorescence in situ hybridization, quantitative polymerase chain reaction (PCR), and breakpoint-specific ...

      Oculofaciocardiodental syndrome (OFCD) is an X-linked dominant disorder associated with male lethality, presenting with congenital cataract, dysmorphic face, dental abnormalities and septal heart defects. Mutations in BCOR (encoding BCL-6-interacting corepressor) cause OFCD. Here, we report on a Korean family with common features of OFCD including bilateral 2nd–3rd toe syndactyly and septal heart defects in three affected females (mother and two daughters). Through the mutation screening ...

      PURPOSE: Congenital cataract is one of the most frequent causes of visual impairment and childhood blindness. Approximately one quarter to one third of congenital cataract cases may have a genetic cause. However, phenotypic variability and genetic heterogeneity hamper correct genetic diagnosis. In this study, we used whole-exome sequencing (WES) to identify pathogenic mutations in two Korean families with congenital cataract.

      METHODS: Two affected members from each family were pooled and ...

      Hirotomo Saitsu, Noboru Mizushima, Naomichi Matsumoto and colleagues report the identification of de novo mutations in WDR45 that cause static encephalopathy of childhood with neurodegeneration in adulthood. WDR45 encodes a homolog of the yeast autophagy protein Atg18.

      Early-onset epileptic encephalopathies (EOEE) are severe neurological disorders characterized by frequent seizures accompanied by developmental regression or retardation. Whole-exome sequencing of 12 patients together with five pairs of parents and subsequent Sanger sequencing in additional 328 EOEE patients identified two de novo frameshift and one missense mutations in SLC35A2 at Xp11.23, respectively. The three patients are all females. X-inactivation analysis of blood leukocyte DNA ...

      We describe a 33-year-old male patient with mental retardation and cerebellar ataxia whose brain magnetic resonance imaging (MRI) showed diffuse central hypomyelination. The associated hypogonadotropic hypogonadism and hypodontia were consistent with the clinical diagnosis of 4H syndrome. Two compound heterozygous mutations in POLR3A were found: p.Met852Val and p.Asn1249His. MRI of the brain showed cerebellar atrophy, atrophy of the corpus callosum, and diffuse hypomyelination extending ...

      Microphthalmia with limb anomalies (MLA), also known as Waardenburg anophthalmia syndrome or ophthalmoacromelic syndrome, is a rare autosomal recessive disorder. Recently, we and others successfully identified SMOC1 as the causative gene for MLA. However, there are several MLA families without SMOC1 abnormality, suggesting locus heterogeneity in MLA. We aimed to identify a pathogenic mutation in one Lebanese family having an MLA-like condition without SMOC1 mutation by whole-exome ...
