Distribution of CYP2C8 and CYP2C9 amino acid substitution alleles in South Indian diabetes patients: A genotypic and computational protein phenotype study.

The CYP2C8 and CYP2C9 are two major isoforms of the cytochrome P450 enzyme family, which is involved in drug response, detoxification, and disease development. This study describes the differential distribution of amino acid substitution variants of CYP2C8 (*2-I269F & *3-R139K) and CYP2C9 (*2-C144R & *3-L359A) genes in 234 type 2 diabetes mellitus (T2DM) patients and 218 healthy controls from Andhra Pradesh, South India. Single locus genotype analysis has revealed that homozygous recessive genotypes of 2C8*2-TT (P ≤ .

Variations in the GST activity are associated with single and combinations of GST genotypes in both male and female diabetic patients.

In the present cross sectional study, we aimed to ascertain the relative associations of GST genotypes with GST activity variations and also with the risk to DMT2 predisposition among men and women separately. Clinical samples obtained from 244 DMT2 cases (120 Males and 124 Females) and 228 controls (117 Males and 111 Females) belonging to Asian Indian ethnicity were used to test for glycemic index, lipid profile, GST activity and GST genotypes. The frequencies of single and combinations of GST genotypes were statistically examined for their association with DMT2 risk among both study groups.

Structural and functional characterization of pathogenic non- synonymous genetic mutations of human insulin-degrading enzyme by in silico methods.

Insulin-degrading enzyme (IDE) is a key protease involved in degrading insulin and amyloid peptides in human body. Several non-synonymous genetic mutations of IDE gene have been recently associated with susceptibility to both diabetes and Alzheimer's diseases. However, the consequence of these mutations on the structure of IDE protein and its substrate binding characteristics is not well elucidated.

In silico analysis of Single Nucleotide Polymorphisms (SNPs) in human BRAF gene.

BRAF gene mutations are frequently seen in both inherited and somatic diseases. However, the harmful mutations for BRAF gene have not been predicted in silico. Owing to the importance of BRAF gene in cell division, differentiation and secretion processes, the functional analysis was carried out to explore the possible association between genetic mutations and phenotypic variations.
