GeneDx RCV000519963 SCV000621492 uncertain significance not provided 2017-10-20 criteria provided, single submitter clinical testing The P393A variant in the ZIC1 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The P393A variant is observed in 1/8,718 (0.012%) alleles from individuals of African background in large population cohorts (Lek et al., 2016). The P393A 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 is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret P393A as a variant of uncertain significance.
