RCV002028084 | SCV002309623 | uncertain significance | Lower motor neuron syndrome with late-adult onset; Frontotemporal dementia and/or amyotrophic lateral sclerosis 2; Autosomal dominant mitochondrial myopathy with exercise intolerance | 2021-10-02 | 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: "Not Available"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with CHCHD10-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces serine with leucine at codon 39 of the CHCHD10 protein (p.Ser39Leu). The serine residue is weakly conserved and there is a large physicochemical difference between serine and leucine. |
