RCV001233635 | SCV001406239 | uncertain significance | Hereditary spastic paraplegia 7 | 2023-10-29 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 26 of the SPG7 protein (p.Gly26Cys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with SPG7-related conditions. ClinVar contains an entry for this variant (Variation ID: 960164). 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 SPG7 protein function with a negative predictive value of 95%. 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. |
| Athena Diagnostics | RCV003482351 | SCV004229210 | uncertain significance | not provided | 2023-02-16 | criteria provided, single submitter | clinical testing | Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is uninformative in assessment of its pathogenicity (http://gnomad.broadinstitute.org). Computational tools predict that this variant is not damaging. |
