Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 1P and 1B. PP3BP6

The NM_000251.3(MSH2):ā€‹c.391T>Gā€‹(p.Phe131Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000242 in 1,613,928 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F131S) has been classified as Uncertain significance.

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]
