The c.1979_1980delAAinsG pathogenic mutation, located in coding exon 4 of the MSH6 gene, results from the deletion of two nucleotides and insertion of one nucleotide at positions 1979 to 1980, causing a translational frameshift with a predicted alternate stop codon (p.K660Rfs*3). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.

HelpRecord last updated May 01, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
