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 Benign. Variant got -8 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 insulin-resistance syndrome type A, hyperinsulinism due to INSR deficiency, Rabson-Mendenhall syndrome, Donohue syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.013263226).

BP6

Variant 19-7184331-G-A is Benign according to our data. Variant chr19-7184331-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 211200.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000828 (126/152092) while in subpopulation AFR AF= 0.00268 (111/41494). AF 95% confidence interval is 0.00227. There are 0 homozygotes in gnomad4. There are 59 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.

The INSR c.959C>T variant is predicted to result in the amino acid substitution p.Thr320Met. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.26% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/19-7184342-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
