GeneDx RCV000484856 SCV000574299 uncertain significance not provided 2017-03-20 criteria provided, single submitter clinical testing The A4611G variant in the USH2A gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The A4611G variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The A4611G variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. A missense variant in the same residue (A4611V) has been reported in an individual with type II Usher syndrome, supporting the functional importance of this region of the protein, although, A4611V was reported in cis with a second USH2A gene variant and it is unknown if this individual also harbored a variant in trans on their second USH2A allele (Nakanishi et al., 2009). We interpret A4611G as a variant of uncertain significance.
