Description

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in an individual with two Lynch syndrome-associated cancers; however, tumor studies demonstrated microsatellite stability, normal protein expression on immunohistochemistry, and BRAF V600E was not detected (Kraus et al., 2015); This variant is associated with the following publications: (PMID: 18822302, 21120944, 25142776)
