GeneDx RCV000195741 SCV000252001 uncertain significance not provided 2018-09-05 criteria provided, single submitter clinical testing The R781W variant in the OPA1 gene has been reported previously in association with optic atrophy, in an individual who was heterozygous for the R781W variant only, and in an individual who was heterozygous for the R781W variant and a second OPA1 variant (Ferré et al., 2009; Chevrollier et al., 2008). The R781W variant is observed in 15/52198 (0.029%) alleles from individuals of European background, in the ExAC dataset (Lek et al., 2016). The R781W 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. We interpret R781W as a variant of uncertain significance.
Illumina Clinical Services Laboratory,Illumina RCV000287680 SCV000442634 likely benign Autosomal dominant optic atrophy classic form 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
