Labcorp Genetics (formerly Invitae), Labcorp RCV001345781 SCV001539920 uncertain significance Aicardi-Goutieres syndrome 2 2021-09-02 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with histidine at codon 9 of the RNASEH2B protein (p.Asp9His). The aspartic acid residue is weakly conserved and there is a moderate physicochemical difference between aspartic acid and histidine. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This variant has not been reported in the literature in individuals affected with RNASEH2B-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: "Tolerated"; PolyPhen-2: "Not Available"; 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.
