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]

Classification according to ACMG Germline Pathogenicity v2019

Specifications for MSH2 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 points.

PM2

Very rare in gnomAD for AD/XL gene (popmax AF < threshold/10) — PM2; GnomAD popmax AF = 0 — very rare for AD+AR gene (base 0.0001, raised to 0.0005 by highest known P/LP ClinVar AF 0.00268) — PM2 moderate.

BP6

ClinVar 2-star benign — strong (BP6); ClinVar germline classification: Benign/Likely Benign, 2 star(s).

BP7

Synonymous variant at non-conserved position with no predicted splicing impact (BP7); Synonymous at non-conserved position, no splicing concern — benign (BP7).
