RCV000576355 | SCV000678206 | uncertain significance | Classic homocystinuria | 2017-08-01 | criteria provided, single submitter | clinical testing | CBS NM_000071.2 exon12 p.Ala361Val (c.1082C>T): This variant has not been reported in the literature and is not present in large control databases. Evolutionary conservation and computational predictive tools suggest that this variant may impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. |

RCV002232200 | SCV001560877 | uncertain significance | HYPERHOMOCYSTEINEMIA, THROMBOTIC, CBS-RELATED | 2021-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine with valine at codon 361 of the CBS protein (p.Ala361Val). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and valine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with CBS-related conditions. ClinVar contains an entry for this variant (Variation ID: 487458). 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: "Tolerated"; PolyPhen-2: "Possibly 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. |
