Genes affected

INSR (HGNC:6091): (insulin receptor) This gene encodes a member of the receptor tyrosine kinase family of proteins. The encoded preproprotein is proteolytically processed to generate alpha and beta subunits that form a heterotetrameric receptor. Binding of insulin or other ligands to this receptor activates the insulin signaling pathway, which regulates glucose uptake and release, as well as the synthesis and storage of carbohydrates, lipids and protein. Mutations in this gene underlie the inherited severe insulin resistance syndromes including type A insulin resistance syndrome, Donohue syndrome and Rabson-Mendenhall syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2015]

Potent mutations in INSR gene can lead to insulin resistance, which presents as impaired glucose tolerance, early onset type 2 diabetes, post prandial hyperglycemia and increased insulin requirement in type 1 diabetes. These mutations in INSR gene can also predispose to coronary artery disease, metabolic syndrome, polycystic ovarian disease and non alcoholic fatty liver disease.However, the role of this particular variant rs777565396 with early onset diabetes mellitus is yet to be ascertained. -
