RCV000289545 | SCV000329595 | likely pathogenic | not provided | 2016-10-07 | criteria provided, single submitter | clinical testing | The F498Y variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. It has been reported in a meeting abstract in association with cardio-faciocutaneous syndrome (Cheon et al., 2012). The F498Y 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. F498Y 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, and in silico analysis predicts this variant is probably damaging to the protein structure/function. Missense variants in nearby residues (K499E/N, E501K/V/G/A) have been reported in the Human Gene Mutation Database in association with cardio-facio-cutaneous syndrome (Stenson et al., 2014), supporting the functional importance of this region of the protein. Therefore, we consider this variant to be likely pathogenic. |
