GeneDx RCV000213373 SCV000279337 uncertain significance not provided 2016-03-07 criteria provided, single submitter clinical testing This variant is denoted MSH6 c.685G>A at the cDNA level, p.Glu229Lys (E229K) at the protein level, and results in the change of a Glutamic Acid to a Lysine (GAG>AAG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. MSH6 Glu229Lys 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 Glutamic Acid and Lysine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. MSH6 Glu229Lys occurs at a position that is conserved in mammals and is not located in a known functional domain (Kariola 2002). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available information, it is unclear whether MSH6 Glu229Lys is pathogenic or benign. We consider it to be a variant of uncertain significance.
