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 made for transcript

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
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 insulin-resistance syndrome type A, hyperinsulinism due to INSR deficiency, Rabson-Mendenhall syndrome, Donohue syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.971
PP5
Variant 19-7267559-G-C is Pathogenic according to our data. Variant chr19-7267559-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 14711.Status of the report is no_assertion_criteria_provided, 0 stars.
