GeneDx RCV000479982 SCV000571942 likely pathogenic not provided 2016-10-17 criteria provided, single submitter clinical testing The R488Q variant in the POMGNT1 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The R488Q variant was not observed in approximately 6500 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 R488Q 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. Missense variants in nearby residues (C490Y and P493R) have been reported in the Human Gene Mutation Database in association with POMGNT1-related disorders (Stenson et al., 2014), supporting the functional importance of this region of the protein. The R488Q variant is a strong candidate for a pathogenic variant.
