BACKGROUND Charcot-Marie-Tooth disease (CMT) is the most common inherited peripheral neuropathy. A great number of causative genes have been described in CMT, and among them, the heterozygous duplication of peripheral myelin protein-22 (PMP22) is the major cause. Although the missense mutation in PMP22 is rarely reported, it has been demonstrated to be associated with CMT. This study described ...
OBJECTIVE To describe the simultaneous occurence of an autosomal dominant inherited MSX1 mutation and an X-linked recessive inherited EDA mutation in one Chinese family with nonsyndromic oligodontia. METHODS Clinical data of characteristics of tooth agenesis were collected. MSX1 and EDA gene mutations were detected in a Chinese family of non-syndromic oligodontia. RESULTS Mild hypodontia in...
In a variety of solid cancers, missense mutations in the well-established TP53 tumor suppressor gene may lead to the presence of a partially-functioning protein molecule, whereas mutations affecting the protein encoding reading frame, often referred to as null mutations, result in the absence of p53 protein. Both types of mutations have been observed in the same cancer type. As the resulting tu...
Pelizaeus-Merzbacher disease (PMD) is a form of X-linked leukodystrophy caused by mutations in the proteolipid protein 1 (PLP1) gene. Although PLP1 proteins with missense mutations have been shown to accumulate in the rough endoplasmic reticulum (ER) in disease model animals and cell lines transfected with mutant PLP1 genes, the exact pathogenetic mechanism of PMD has not previously been clarif...
To illustrate the variable clinical presentations and rates of progression in familial hypertrophic cardiomyopathy (FHC), phenotypes and genotypes were compared in three FHC families with different genetic defects. In the first family, the FHC abnormality was a protein truncating mutation (Gln969X) in the cardiac myosin binding protein C gene. The second family had a missense change (Asn755Lys)...
Four well characterized Drosophila rhodopsin (ninaE) mutants possess low levels of rhodopsin in their major class of photoreceptors. The molecular defect present in each strain was determined by isolating and sequencing the mutant genes. Two missense mutants encode proteins which have arginine residues positioned within membrane-spanning domains. The third missense mutant eliminates a proline f...
: Hypohidrotic ectodermal dysplasia (HED) is the most common type of that result faulty development leading to such defects as hypotrichosis, anodontia or hypodontia, and hypohidrosis anhidrosis. X-linked HED caused by mutations in ectodysplasin A (EDA) gene accounts for 90% all cases. Autosomal other involved genes, EDA-receptor (EDAR) gene. In this study, we included two distinct families wit...
We identified a missense mutation (T185-->C, Phe62-->Ser) in the neurofibromatosis 2 (NF2) gene in a family with mild and severe NF2 phenotypes. This mutation was previously reported in an unrelated family in which all affected individuals had mild phenotypes. These data demonstrate a lack of correlation between NF2 genotype and NF2 phenotype for this mutation.
schimke immuno-osseous dysplasia is a rare autosomal recessive multisystem disorder characterized by steroid-resistant nephrotic syndrome, immunodeficiency, and spondyloepiphy-seal dysplasia. mutations in swi/snf2 related, matrix associated, actin dependent regulator of chromatin, subfamily a-like 1 (smarcal1) gene are responsible for the disease. the present report describes, for the first tim...
Adrenoleukodystrophy (ALD) is an X-linked genetic disorder, characterized by demyelination in the central nervous system and adrenal insufficiency. Human induced pluripotent stem cell (hiPSC) lines derived from two Japanese male patients with ALD were generated skin fibroblasts using retroviral vectors. The hiPSC showed self-renewal pluripotency, carried either a missense or nonsense mutation A...
