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: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.63).

BP6

Variant 19-7267807-A-G is Benign according to our data. Variant chr19-7267807-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 195041.

BP7

Synonymous conserved (PhyloP=-0.078 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000834 (127/152318) while in subpopulation AFR AF = 0.00236 (98/41578). AF 95% confidence interval is 0.00198. There are 0 homozygotes in GnomAd4. There are 58 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
