Invitae RCV001212781 SCV001384378 pathogenic Spastic paraplegia 2022-07-18 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. 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"). ClinVar contains an entry for this variant (Variation ID: 942744). This variant is present in population databases (rs761060634, gnomAD 0.0009%). This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 449 of the CYP7B1 protein (p.Cys449Tyr). This missense change has been observed in individual(s) with clinical features of hereditary spastic paraplegia (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals.
