GeneDx RCV000414612 SCV000491279 likely pathogenic not provided 2016-08-30 criteria provided, single submitter clinical testing The Y202C variant has been published previously in association with EEC syndrome (van Bokhoven et al., 2002). The 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. Y202C 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 within the DNA-binding domain that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. While functional studies on the Y202C variant have been published and show Y202C leads to decreased degradation of the TP63 protein, the molecular effects of Y202C over-expression or Y202C's effect on transcriptional activity were not discussed (Browne et al., 2011). Therefore, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded.
