CONCLUSIONS Patients with hereditary hemorrhagic telangiectasia genotype ALK-1 (HHT2-ALK-1) with nonsense mutation demonstrated tendentially higher health-related quality of life (HR-QOL) scores than patients with HHT with genotype ENG (HHT1-ENG) with missense mutation. OBJECTIVE HHT, also known as Osler-Weber-Rendu syndrome, comprises different expressions depending on genetic type and mutat...
AIM The autosomal recessive hypercholesterolemia (ARH) gene is located on chromosome 1p35 and encodes a 308-amino acid protein containing a phosphotyrosine-binding domain. Several researchers have identified mutations of ARH that cause autosomal recessive hypercholesterolemia; however, it remains unknown whether this gene is involved in common hypercholesterolemia. METHODS AND RESULTS We sear...
Autosomal dominant non-syndromic hearing loss is highly heterogeneous, and eyes absent 4 (EYA4) is a disease-causing gene. Most EYA4 mutations founded in the Eya-homologous region, however, no deafness causative missense mutation in variable region of EYA4 have previously been found. In this study, we identified a pathogenic missense mutation located in the variable region of the EYA4 gene for ...
In a Dutch pedigree suffering from autosomal dominant nonsyndromic hearing impairment (ADNSHI), linkage was found to the locus for DFNA15, with a two-point logarithm of the odds (LOD) score of 5.1. Sequence analysis of the POU4F3 gene that is involved in DFNA15 revealed the presence of a missense mutation (c.865C>T), segregating with the deafness in this family. The mutation is predicted to res...
BACKGROUND Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the biosynthesis of the catecholamines dopamine, norepinephrine, and epinephrine. Recently, mutations were identified in cases of autosomal recessive dopa-responsive dystonia and infantile parkinsonism. We describe a patient with severe symptoms and a new missense mutation in TH. METHODS Relevant metabolites in urine and...
PURPOSE Several studies indicated that the expression level of MLL3 gene in gastric cancer tissue was associated with prognosis, and previous studies also suggested that genetic polymorphisms of MLL3 were related to the risk for gastric cancer. The present study aimed to investigate the association of a missense mutation (S3660L) in the MLL3 gene with gastric cancer risk in a Chinese population...
Purpose. To report the identification of the first de novo UBIAD1 missense mutation in an individual with Schnyder corneal dystrophy (SCD). Methods. A slit lamp examination was performed on a 47-year-old woman without a family history of corneal disorders. The proband's parents, two sisters, and son were also examined and genomic DNA from all six individuals was collected. The exons and exon-in...
A subtype of neuronal ceroid lipofuscinosis (NCL) is well recognized which has a clinical course consistent with juvenile NCL (JNCL) but the ultrastructural characteristics of infantile NCL (INCL): granular osmiophilic deposits (GROD). Evidence supporting linkage of this phenotype, designated vJNCL/GROD, to the INCL region of chromosome 1p32 was demonstrated (pairwise lod score with D1S211 , Z ...
Large-scale sequencing of cancer genomes has uncovered thousands of DNA alterations, but the functional relevance of the majority of these mutations to tumorigenesis is unknown. We have developed a computational method, called Cancer-specific High-throughput Annotation of Somatic Mutations (CHASM), to identify and prioritize those missense mutations most likely to generate functional changes th...
Neurofibromatosis type 1 (NF1) is a common genetic disorder characterized by the occurrence of nerve sheath tumors and considerable clinical heterogeneity. Some translational studies have been limited by the lack of animal models available for assessing patient-specific mutations. In order to test therapeutic approaches that might restore function to the mutated gene or gene product, we develop...
