Monogenic Diabetes VCEP

The c.518_526+37del variant in the HNF1 homeobox A gene, HNF1A, is a 46 base pair deletion that removes a canonical splice donor site in intron 2 of NM_000545.8. This variant is predicted to cause skipping of biologically-relevant exon 2 of 10, resulting in a frameshift, leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism (PVS1; PMID: 23348805). This variant is also absent from gnomAD v2.1.1 (PM2_Supporting). In summary, c.518_526+37del meets the criteria to be classified as likely pathogenic for monogenic diabetes. ACMG/AMP criteria applied, as specified by the ClinGen MDEP (Specification version For HNF1A: version 1.1, Approved 9/30/21): PVS1, PM2_Supporting.

PM2_Supporting

This variant is absent from gnomAD v2.1.1.

PVS1

This variant is predicted to cause skipping of biologically-relevant exon 2 of 10, resulting in a frameshift, leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism
