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]

Insulin-resistant diabetes mellitus AND acanthosis nigricans Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 12, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

Hyperinsulinism due to INSR deficiency Benign:1
Likely benign, criteria provided, single submitterresearchClinical Genomics, Uppaluri K&H Personalized Medicine Clinic-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 rs41352749 with early onset diabetes mellitus is yet to be ascertained. -
