GeneDx RCV000493267 SCV000583154 likely pathogenic not provided 2015-08-18 criteria provided, single submitter clinical testing The R4789W variant has been reported previously as a likely pathogenic variant in a cohort of patients diagnosed with Usher syndrome type 2 (Besnard et al. 2012). The R4789W 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 R4789W 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. Missense variants in this residue and in a nearby residue (R4789Q, N4885S) have been reported in the Human Gene Mutation Database in association with Usher syndrome (Stenson et al., 2014). Therefore, based on the currently available information, R4789W is a candidate for a disease-causing variant, although the possibility that it is a benign polymorphism cannot be completely excluded.
Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000609544 SCV000710878 likely pathogenic Rare genetic deafness 2016-11-19 criteria provided, single submitter clinical testing The p.Arg4789Trp variant in GPR98 has been reported in 1 individual with Usher s yndrome who was compound heterozygous for a second pathogenic variant in GPR98 ( Besnard 2012). This variant was absent from large population studies. Computati onal prediction tools and conservation analyses suggest that this variant may im pact the protein, though this information is not predictive enough to determine pathogenicity. In summary, although additional studies are required to fully est ablish its clinical significance, this variant is likely pathogenic.
