RCV000616850 | SCV000731686 | pathogenic | Lynch syndrome | 2017-06-23 | criteria provided, single submitter | clinical testing | The p.Asn547GlufsX4 (NM_000251.2 c.1637_1638insA) variant in MSH2 has not been p reviously reported in individuals with Lynch syndrome and was absent from large population studies. This variant is predicted to cause a frameshift, which alter s the protein?s amino acid sequence beginning at position 547 and leads to a pre mature termination codon 4 amino acids downstream. This alteration is then predi cted to lead to a truncated or absent protein. Heterozygous loss of function of the MSH2 gene is an established disease mechanism in individuals with Lynch synd rome. In summary, this variant meets criteria to be classified as pathogenic for Lynch syndrome in an autosomal dominant manner based upon the predicted impact to the protein. |
