Invitae RCV001054383 SCV001218694 uncertain significance Congenital hyperammonemia, type I 2021-08-28 criteria provided, single submitter clinical testing This sequence change replaces glycine with alanine at codon 258 of the CPS1 protein (p.Gly258Ala). The glycine residue is moderately conserved and there is a small physicochemical difference between glycine and alanine. This variant is present in population databases (rs778299777, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with CPS1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
