GeneDx RCV000413720 SCV000490934 pathogenic not provided 2015-03-06 criteria provided, single submitter clinical testing The G60R variant has been reported previously is association with juvenile myelomonocytic leukemia (Loh et al., 2004). The G60R variant 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. The G60R variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. Missense variants at this residue and in nearby residues (N58K, G60S, G60C, G60V, G60A, D61N, Y62N, Y63C) have been reported in the Human Gene Mutation Database in association with Noonan syndrome (Stenson et al., 2014), supporting the functional importance of this region of the protein. Therefore, G60R is interpreted to be a disease-causing variant
