Single amino acid polymorphism in aldehyde dehydrogenase gene superfamily.

Abstract

The aldehyde dehydrogenase gene superfamily comprises of 19 genes and 3 pseudogenes. These superfamily genes play a vital role in the formation of molecules that are involved in life processes, and detoxification of endogenous and exogenous aldehydes. ALDH superfamily genes associated mutations are implicated in various diseases, such as pyridoxine-dependent seizures, gamma-hydroxybutyric aciduria, type II Hyperprolinemia, Sjogren-Larsson syndrome including cancer and Alzheimer's disease. Accumulation of large DNA variations data especially Single Amino acid Polymorphisms (SAPs) in public databases related to ALDH superfamily genes insisted us to conduct a survey on the disease associated mutations and predict their function impact on protein structure and function. Overall this study provides an update and highlights the importance of pathogenic mutations in associated diseases. Using KD4v and Project HOPE a computational based platform, we summarized all the deleterious properties of SAPs in ALDH superfamily genes by the providing valuable insight into structural alteration rendered due to mutation. We hope this review might provide a way to define the deleteriousness of a SAP and helps to understand the molecular basis of the associated disease and also permits precise diagnosis and treatment in the near future.
