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]

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 13 ACMG points.
PVS1
?
Splicing variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
PM2
?
Very rare variant in population databases, with high coverage;
PP3
?
No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
PP5
?
