The p.Cys297Phe variant has not been reported in the literature nor previously identified by our laboratory. The Cys residue is conserved across mammals and computational analyses (PolyPhen2, SIFT, AlignGVGD) suggest that the Phe variant may impact the protein. However, this information is not predictive enough to assume pathogenicity. The presence of this variant in combination with a reported pathogenic variant increases the likelihood that the p.Cys297Phe variant is pathogenic. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more pathogenic role for this variant. This variant is classified as a Predicted Pathogenic.
