Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4BP7BS1

This summary comes from the ClinGen Evidence Repository: The MSH2 c.1563T>C variant is a synonymous variant, p.(Tyr521=). It is present in GnomAD v2.1.1 (non-cancer dataset) and gnomAD v4.1 within the Maximum Credible Allele Frequency (MCAF) cutoff 0.0001-0.001 (0.01-0.1%). It is not predicted to affect splicing according to predictions from http://priors.hci.utah.edu/PRIORS and SpliceAI. Therefore, this variant is classified as likely benign.

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]
