Genes affected

MSH2 (HGNC:7325): (mutS homolog 2) This locus is frequently mutated in hereditary nonpolyposis colon cancer (HNPCC). When cloned, it was discovered to be a human homolog of the E. coli mismatch repair gene mutS, consistent with the characteristic alterations in microsatellite sequences (RER+ phenotype) found in HNPCC. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: This is an intronic variant. The variant has been reported in one patient with a sebaceous adenoma whose mother had CRC at age 56. Staining of MSH2 in the tumor was normal (Everett 2014). This variant is present in ExAC at a MaxMAF of 0.04% (30 alleles) and in gnomAD at 0.05% (68 alleles). It is classified in ClinVar as likely benign by Invitae (1 star).
