GeneDx RCV000439170 SCV000529435 uncertain significance not provided 2017-10-09 criteria provided, single submitter clinical testing The T93R variant in the ATP7A gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The T93R 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 T93R variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. As an alternate mechanism, multiple in silico algorithms predict that c.278C>G (aka T93R) might create a cryptic acceptor site in exon 3 which may supplant the natural donor site. However, in the absence of RNA/functional studies, the actual effect of c.278C>G in this individual is unknown.We interpret T93R as a variant of uncertain significance.
