Description

The c.3556+1G>A intronic pathogenic mutation results from a G to A substitution one nucleotide after coding exon 6 of the MSH6 gene. In silico splice site analysis predicts that this alteration will weaken the native splice donor site. RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data). Other alterations impacting the same donor site (c.3556+1G>T and c.3556+2T>G) have been shown to have a similar impact on splicing and were identified in probands meeting Amsterdam I/II criteria for Lynch syndrome/HNPCC and/or had loss of MSH6 expression in their tumors by immunohistochemistry (Ambry internal data; Hirotsu Y et al. Mol Genet Genomic Med, 2015 Sep;3:459-66). Alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as a disease-causing mutation.
