GeneDx RCV000519619 SCV000618343 uncertain significance not provided 2017-03-17 criteria provided, single submitter clinical testing This variant is denoted MSH6 c.3400G>C at the cDNA level, p.Gly1134Arg (G1134R) at the protein level, and results in the change of a Glycine to an Arginine (GGA>CGA). This variant was observed in at least one individual undergoing multi-gene panel testing (LaDuca 2017). MSH6 Gly1134Arg was not observed in large population cohorts (NHLBI Exome Sequencing Project, The 1000 Genomes Consortium 2015, Lek 2016). Since Glycine and Arginine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. MSH6 Gly1134Arg occurs at a position that is conserved across species and is located within the ATPase domain and within the ATP-binding motif (Kariola 2002). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available evidence, it is unclear whether MSH6 Gly1134Arg is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
