Genes affected
INS (HGNC:6081): (insulin) This gene encodes insulin, a peptide hormone that plays a vital role in the regulation of carbohydrate and lipid metabolism. After removal of the precursor signal peptide, proinsulin is post-translationally cleaved into three peptides: the B chain and A chain peptides, which are covalently linked via two disulfide bonds to form insulin, and C-peptide. Binding of insulin to the insulin receptor (INSR) stimulates glucose uptake. A multitude of mutant alleles with phenotypic effects have been identified, including insulin-dependent diabetes mellitus, permanent neonatal diabetes diabetes mellitus, maturity-onset diabetes of the young type 10 and hyperproinsulinemia. There is a read-through gene, INS-IGF2, which overlaps with this gene at the 5' region and with the IGF2 gene at the 3' region. [provided by RefSeq, May 2020]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.9).
BP6
Variant 11-2161146-C-T is Benign according to our data. Variant chr11-2161146-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 435505.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=1}.
BS2
High AC in GnomAdExome4 at 13 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
