GeneDx RCV000236195 SCV000293274 uncertain significance not provided 2015-10-20 criteria provided, single submitter clinical testing This variant is denoted MSH2 c.1883G>A at the cDNA level, p.Gly628Glu (G628E) at the protein level, and results in the change of a Glycine to a Glutamic Acid (GGA>GAA). This variant has not, to our knowledge, been published in the literature as being pathogenic or benign. MSH2 Gly628Glu was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Glycine and Glutamic Acid differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. MSH2 Gly628Glu occurs at a position that is conserved across species and is located in the region of interaction with EXO1 and in the ATPase domain (Lutzen 2008). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether MSH2 Gly628Glu is pathogenic or benign.
