Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM2PM5PP2PP3_StrongPP5_Moderate

The NM_000208.4(INSR):c.3602G>A(p.Arg1201Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,854 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1201G) has been classified as Likely pathogenic.

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: Pathogenic. The variant received 11 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr19-7120678-G-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 3382020.Status of the report is criteria_provided_single_submitter, 1 stars.

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.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.992

PP5

Variant 19-7120677-C-T is Pathogenic according to our data. Variant chr19-7120677-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 14708.Status of the report is criteria_provided_single_submitter, 1 stars.
