A substantial proportion of patients with pulmonary arterial hypertension (PAH) have mutations in the Bone Morphogenetic Protein Receptor type-2 (BMPR2) gene. PAH due to BMPR2 mutations is inherited as an autosomal dominant trait with several unique features, including a wide variety of mutations, reduced penetrance, a skewed gender ratio, variable(More)
PURPOSE The purpose of this study was to undertake thorough genetic analysis of the bone morphogenetic protein type 2 receptor (BMPR2) gene in patients with pulmonary arterial hypertension. METHODS We conducted a systematic analysis for larger gene rearrangements together with conventional mutation analysis in 152 pulmonary arterial hypertension patients(More)
Recent advances in the analysis of patients with congenital abnormalities using array-based comparative genome hybridization (aCGH) have uncovered two types of genomic copy-number variants (CNVs); pathogenic CNVs (pCNVs) relevant to congenital disorders and benign CNVs observed also in healthy populations, complicating the screening of disease-associated(More)
We report on a 2-year-old Japanese girl with Cornelia-de Lange syndrome (CdLS) who had mental and growth retardation, together with characteristic facial anomalies and mild extremity malformations. She had a balanced chromosomal translocation, 46,XX,t(5;13)(p13.1;q12.1) de novo. Surprisingly, this was the same translocation that had provided a clue to the(More)
BACKGROUND It is unclear whether the incidence of febrile seizure (FS) in children with Down syndrome (DS) is higher or lower than in the general population. In this study, we investigated the incidence of FS in DS patients using mailed questionnaires. METHODS The questionnaires were distributed to parents or caregivers of DS patients attending Osaka(More)
BACKGROUND Japanese nationwide survey reported that Down syndrome (DS) is less-frequently occurring comorbidity in Kawasaki disease (KD). Although altered immune responses are frequently observed in DS, no studies have focused treatment response and risk for coronary artery abnormalities (CAAs) in DS with KD. The aim of this study was to evaluate clinical(More)
The vascular type of Ehlers-Danlos syndrome (EDS), EDS type IV (Online Mendelian Inheritance in Man [MIM] #130050) is characterized by thin, translucent skin, easy bruising, and arterial, intestinal, and/or uterine fragility during pregnancy, which may lead to sudden death. It is an autosomal dominant inherited disorder caused by type III procollagen gene(More)
