Invitae RCV000794321 SCV000933721 uncertain significance Spastic paraplegia 2021-08-28 criteria provided, single submitter clinical testing This sequence change replaces lysine with asparagine at codon 1555 of the SACS protein (p.Lys1555Asn). The lysine residue is highly conserved and there is a moderate physicochemical difference between lysine and asparagine. This variant is present in population databases (rs769852897, ExAC 0.003%). This variant has not been reported in the literature in individuals affected with SACS-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.
