Labcorp Genetics (formerly Invitae), Labcorp RCV001884237 SCV002153493 uncertain significance Hereditary spastic paraplegia 11 2021-09-21 criteria provided, single submitter clinical testing This sequence change replaces tyrosine with cysteine at codon 762 of the SPG11 protein (p.Tyr762Cys). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and cysteine. This variant is present in population databases (rs747681565, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with SPG11-related conditions. 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 expected to disrupt SPG11 protein function. 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.
