Congruency in the prediction of pathogenic missense mutations: state-of-the-art web-based tools

BY IN Functional impact prediction, Journal Club, Review NO COMMENTS YET , , , , , , ,

Deep sequencing initiatives are identified a remarkable quantity of single nucleotide polymorphisms yet only approximately half are nonsynonymous amino acid substitutions that could potentially affect protein function. A confusing array of tools are available to help identify the few gene-coding variants that actually cause or confer susceptibility to disease. In this brief, Castellana and Mazza


Sequence variation in G-protein-coupled receptors: analysis of single nucleotide polymorphisms

BY IN Functional impact prediction, Journal Club, Machine learning NO COMMENTS YET , , , , , , , ,

G-protein-coupled receptors (GPCRs) play an important role in many physiological processes such as signal transduction and are frequently the targets for the majority of prescription drugs such as beta-blockers and anti-histamines. Understanding the role of sequence variations such as SNPs in GPCRs has potential implications for elucidating disease pathogenesis mechanisms and drug efficacy issues. In


Prediction of Missense Mutation Functionality Depends on Both the Algorithm and Sequence Alignment Employed

BY IN Functional impact prediction, Journal Club 1 COMMENT , , , , , , , , ,

A number of algorithms have been developed to predict the impact of missense mutations on protein structure and function using sequence and structure-based approaches, notably SIFT, PolyPhen-2, Xvar, and Align-GVGD. In this study, Hicks et al. demonstrate that accurately predicting the impact of missense mutations on protein function depends on the algorithm used, the type
