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 gene, where missense usually causes diseases (based on misZ statistic), INSR. . Gene score misZ 3.8314 (greater than the threshold 3.09). Trascript score misZ 5.4593 (greater than threshold 3.09). GenCC has associacion of gene with 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.
