Invitae | RCV001315413 | SCV001505987 | uncertain significance | Spastic paraplegia | 2020-09-24 | criteria provided, single submitter | clinical testing | 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SACS protein function. This variant has been observed in individual(s) with clinical features of hereditary spastic paraplegia (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with lysine at codon 1247 of the SACS protein (p.Gln1247Lys). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and lysine. |
