Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 2P and 3B. PM1BP4_ModerateBP6

The NM_000251.3(MSH2):c.1378A>G(p.Met460Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000376 in 1,596,962 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. M460I) has been 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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PM1

In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 14 benign, 33 uncertain in NM_000251.3

BP4

Computational evidence support a benign effect (MetaRNN=0.19934508).

BP6

Variant 2-47445649-A-G is Benign according to our data. Variant chr2-47445649-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 237367.
