Description

The p.Val273Ala variant in MSH2 has not been previously reported in individuals with Lynch syndrome but has been identified in 5/10306 of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP r s144288433). Computational prediction tools and conservation analysis do not pro vide strong support for or against an impact to the protein. In summary, the cli nical significance of the p.Val273Ala variant is uncertain.
