This variant is denoted MSH2 c.1189C>G at the cDNA level, p.Gln397Glu (Q397E) at the protein level, and results in the change of a Glutamine to a Glutamic Acid (CAA>GAA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign germline variant. MSH2 Gln397Glu was not observed at a significant frequency in large population cohorts (Lek 2016). This variant is located within the lever domain as well as the region of interaction with MSH6 and MSH3 (Guerrette 1998, Lutzen 2008, Kansikas 2011). In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether MSH2 Gln397Glu is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
