Sotos syndrome (SoS) is an autosomal dominant overgrowth syndrome with characteristic craniofacial dysmorphic features and various degrees of mental retardation. We previously showed that haploinsufficiency of the NSD1 gene is the major cause of SoS, and submicroscopic deletions at 5q35, including NSD1, were found in about a half (20/42) of our patients(More)
PURPOSE We tested the hypothesis that Sotos syndrome (SoS) due to the common deletion is a contiguous gene syndrome incorporating plasma coagulation factor twelve (FXII) deficiency. The relationship between FXII activity and the genotype at a functional polymorphism of the FXII gene was investigated. METHODS A total of 21 patients including those with the(More)
Mitochondrial very-long-chain acyl-coenzyme A dehydrogenase (VLCAD) was purified from human liver. The molecular masses of the native enzyme and the subunit were estimated to be 154 and 70 kD, respectively. The enzyme was found to catalyze the major part of mitochondrial palmitoylcoenzyme A dehydrogenation in liver, heart, skeletal muscle, and skin(More)
We report on an 11-year-old boy with familial juvenile nephronophthisis type I associated with cerebellar ataxia and nystagmus, but not with ocular motor apraxia. An MRI revealed hypoplasia of the brainstem and vermis, and an enlargement of the fourth ventricle. A molecular genetic analysis demonstrated a homozygous deletion including the NPHP1 gene. These(More)
OBJECTIVE To delineate the significance of maternal uniparental disomy 14 (upd(14)mat) and related disorders in patients with a Prader-Willi syndrome (PWS)-like phenotype. STUDY DESIGN We examined 78 patients with PWS-like phenotype who lacked molecular defects for PWS. The MEG3 methylation test followed by microsatellite polymorphism analysis of(More)
Spondyloepiphyseal dysplasia congenita (SEDC) is a group of rare inherited chondrodysplasias characterized by short stature, abnormal epiphyses, and flattened vertebral bodies. SEDC is usually caused by substitution of glycine residue with another amino acid in the triple helical domains of alpha 1 chains, which consist of type II collagen (COL2A1). Herein,(More)
Infants often develop hypocarnitinemia and resultant hypoglycemia during long-term treatment with antibiotics that contain pivalic acid, but it is unknown whether maternal treatment with such agents during pregnancy induces hypocarnitinemia in fetuses or neonates. A woman at week 28 of pregnancy was prescribed cefcapene pivoxil for 84 consecutive days for(More)
