GeneDx RCV000489565 SCV000577407 uncertain significance not provided 2017-03-30 criteria provided, single submitter clinical testing The D1176N variant in the NPHP4 gene has been reported previously in an individual who underwent whole exome sequencing as part of a study of individuals with autosomal recessive or sporadic retinitis pigmentosa with no apparent syndrome; however, this individual also harbored variants in multiple other genes associated with ocular disorders and additional clinical or family history information was not provided (Katagiri et al., 2014). The D1176N variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The D1176N 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 conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret D1176N as a variant of uncertain significance.
