RCV001001020 | SCV001158128 | uncertain significance | not specified | 2019-02-18 | criteria provided, single submitter | clinical testing | The HSPB8 c.140C>G; p.Ser47Cys variant (rs1183371665), to our knowledge, is not reported in the medical literature or gene specific databases. This variant is found on 2 out of 277,102 chromosomes in the Genome Aggregation Database indicating it is not a common polymorphism. The serine at codon 47 is weakly conserved and computational analyses (SIFT, PolyPhen-2) predict that this variant is tolerated. Due to limited information, the clinical significance of the p.Ser47Cys variant is uncertain at this time. |
Invitae | RCV001223553 | SCV001395709 | uncertain significance | Charcot-Marie-Tooth disease axonal type 2L | 2022-08-21 | criteria provided, single submitter | clinical testing | 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. 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: "Benign"; Align-GVGD: "Class C15"). ClinVar contains an entry for this variant (Variation ID: 811267). This variant has not been reported in the literature in individuals affected with HSPB8-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 47 of the HSPB8 protein (p.Ser47Cys). |
