Fig (Ficus carica) breeding programs that use conventional approaches to develop new cultivars are rare, owing to limited genetic variability and the difficulty in obtaining plants via gamete fusion. Cytosine methylation in plants leads to gene repression, thereby affecting transcription without changing the DNA sequence. Previous studies using random amp.. Read More»

We investigated 2 Chinese families with dyschromatosis symmetrica hereditaria (DSH) and search for mutations in the adenosine deaminase acting on RNA1 (ADAR1) gene in these 2 pedigrees. We performed a mutation analysis of the ADAR1 gene in 2 Chinese families with DSH and reviewed all articles published regarding ADAR1 mutations reported since 2003 by usin.. Read More»

Beta-thalassemia is a life-threatening inherited blood disorder. Rapid characterization of β-globin gene mutations is necessary because of the high frequency of Malaysian β-thalassemia carriers. A combination real-time polymerase chain reaction genotyping assay using TaqMan probes was developed to confirm β-globin gene mutations. In this st.. Read More»

Hereditary hemochromatosis (HH) is the most common genetic disease among individuals of European descent. Two mutations (845G→A, C282Y and 187C→G, H63D) in the hemochromatosis gene (HFE gene) are associated with HH. About 85-90% of patients of northern European descent with HH are C282Y homozygous. The prevalence of .. Read More»

The Mx (myxovirus resistance) gene codes for a protein with antiviral activity. Non-synonymous G/A polymorphism at position 2032 of chicken Mx cDNA results in a change at amino acid 631 of the Mx protein. This mutation has been shown to affect the antiviral activity of the Mx molecule, although recent studies have not confirme.. Read More»

Dyschromatosis symmetrica hereditaria (DSH) is an autosomal dominant pigmentary genodermatosis, characterized by a mixture of hyperpigmented and hypopigmented macules that are mainly present on the dorsal portions of the extremities. The DSH locus was mapped to chromosome 1q11-q12 and, subsequently, pathogenic mutations in the double-stranded RNA-specific.. Read More»

The goal of the current study was to investigate the differences in epidermal growth factor receptor (EGFR) mutation rates in tumor tissue and pleural effusion specimens from patients with lung adenocarcinoma. PCR amplification and gene sequencing were used to detect EGFR mutations in exons 18, 19, 20, and 21 in tumor tissue a.. Read More»

Neurofibromatosis type 1, also known as NF1 or von Recklinghausen’s disease, is a common neurocutaneous syndrome that presents with multiple café-au-lait patches, skinfold freckling, dermatofibromas, neurofibromas, and Lisch nodules. The mutations of the gene NF1, encoding the protein neurofibromin, have been iden.. Read More»

Blocking aldehyde dehydrogenase with the drug disulfiram leads to an accumulation of intracellular acetaldehyde, which negatively affects the viability of the yeast Saccharomyces cerevisiae. Mutants of the yeast gene PSO2, which encodes a protein specific for repair of DNA interstrand cross-links, showed higher sensitivity to .. Read More»

Cleidocranial dysplasia (CCD) is an autosomal-dominant heritable skeletal disease caused by heterozygous mutations in the RUNX2 gene. We studied a Chinese family that included three affected individuals with CCD phenotypes; the clinical features of patients with CCD include delayed closure of fontanelles, frontal bossing, dysp..
