Ambry Genetics | RCV002390222 | SCV002699886 | likely pathogenic | Hereditary cancer-predisposing syndrome | 2022-06-02 | criteria provided, single submitter | clinical testing | The c.1386+1G>C intronic variant results from a G to C substitution one nucleotide after coding exon 8 of the MSH2 gene. This alteration was identified in a Belgian family that met Amsterdam Criteria (Spaepen M et al. Fam Cancer, 2006;5:179-89). This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site. In addition to the clinical data presented in the literature, 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 likely pathogenic. |
