Labcorp Genetics (formerly Invitae), Labcorp RCV001861511 SCV002224704 uncertain significance Spastic paraplegia 2021-08-30 criteria provided, single submitter clinical testing This sequence change replaces glycine with aspartic acid at codon 147 of the CYP7B1 protein (p.Gly147Asp). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and aspartic acid. This variant is present in population databases (rs754730601, ExAC 0.003%). This missense change has been observed in individual(s) with CYP7B1-related conditions (PMID: 24117163, 29482223). ClinVar contains an entry for this variant (Variation ID: 381743). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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.
