hereditary inclusion body myopathy (hibm) is an adult-onset hereditary myopathy, usually with distal onset and quadriceps sparing. this myopathy is autosomal recessive and associated to upd-n-acetylglucosamine-2-epimerase/n-acetylmannosamine kinase (gne) gene mutations. in this study, we report a novel gne homozygous point mutation c.1834t>g that results in amino acid substitution of cysteine 6...

This article proposes a new approach for determining the optimal parameter (β) in Inverse Distance Weighted Method (IDW) spatial interpolation of hydrological data series. is based on genetic algorithm (GA) and finds unique β entire study region, while classical one determines different βs interpolated The proposed four scenarios crossover/mutation: single-point/uniform, single-point/swap, two-...

in this paper, we prove a common fixed point theorem for six mappings (two set valued and four single valued mappings) without assuming compatibility and continuity of any mapping on non complete metric spaces. to prove the theorem, we use a non compatible condition, that is, weak commutativity of type (kb). we show that completeness of the whole space is not necessary for the existence and uni...

P53 tumor suppressor gene, also known as “genome guardian” is mutated in more than half of allkind of cancers. In this study we have investigated the controls of environmental pH for P53 genemutation in point of specific sequence which is prone to mutagenesis. The most probable cancerousmutations occur as point mutations in exons 5-8 of P53 gene. The 175th codon of P53 is the thirdmost mutated ...

background and objective: familial hypercholesterolemia (fh) is an autosomal trait, which is caused by mutations in low density lipoprotein receptor (ldlr) gene. fh penetrance is about 100% and worldwide prevalence for heterozygous subjects is almost 1 in 500 and for homozygous 1 in 1,000,000. the patients are at risk of premature coronary heart disease (chd) due to defective ldlr and hence cho...

There has been a rapid increase in the amount of mutational data due to, amongst other things, an increase in single nucleotide polymorphism (SNP) data and the use of site-directed mutagenesis as a tool to help dissect out functional properties of proteins. Many manually curated databases have been developed to index point mutations but they are not sustainable with the ever-increasing volume o...

Allele-specific oligonucleotides are used widely for the detection of single point mutations in genes. A modification of this assay based on competition has been developed for detection of the Z mutation of alpha 1-antitrypsin (alpha 1-AT). The normal alpha 1-AT allele is referred to as M, and the Z mutation arises from a single base substitution. Amplified DNA products corresponding to homozyg...

A model is investigated in which mutations that affect a complex trait (e.g., heart disease) also affect fitness because the trait is a component of fitness or because the mutations have pleiotropic effects onfitness. Themodel predicts that the genetic variance, and hence the heritability, in the trait is contributed bymutations at low frequency in the population, unless the mean strength of se...

Background & Objective: Mutations in embB306 gene and their association with resistance to ethambutol (EMB) in Mycobacterium tuberculosis (M. tuberculosis) have not been fully investigated. The aim of this study was to investigate the point-mutations in emb306B gene and their association with resistance to EMB in M. tuberculosis. Materials & Methods: This case (M. tuberculosis resistant to EMB...

A biological reporter gene assay was employed to determine the crucial parameters for maximizing selective targeting of a Ha-ras codon 12 point mutation (G----T) using phosphorothioate antisense oligonucleotides. We have tested a series of oligonucleotides ranging in length between 5 and 25 bases, each centered around the codon 12 point mutation. Our results indicate that selective targeting of...
