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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PP2

Missense variant in the INSR gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 29 curated pathogenic missense variants (we use a threshold of 10). The gene has 9 curated benign missense variants. Gene score misZ: 3.8314 (above the threshold of 3.09). Trascript score misZ: 5.4593 (above the threshold of 3.09). GenCC associations: The gene is linked to Rabson-Mendenhall syndrome, hyperinsulinism due to INSR deficiency, Donohue syndrome, insulin-resistance syndrome type A.

BP4

Computational evidence support a benign effect (MetaRNN=0.2417678).

BS1

Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.0000123 (18/1461858) while in subpopulation AFR AF = 0.000209 (7/33478). AF 95% confidence interval is 0.0000975. There are 0 homozygotes in GnomAdExome4. There are 8 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
