Invitae RCV000701524 SCV000830327 uncertain significance Spastic paraplegia 2019-05-18 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with glycine at codon 202 of the SACS protein (p.Asp202Gly). The aspartic acid residue is moderately conserved and there is a moderate physicochemical difference between aspartic acid and glycine. This variant is present in population databases (rs777554091, ExAC 0.007%). This variant has not been reported in the literature in individuals with SACS-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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.
