RCV000637289 | SCV000758737 | uncertain significance | Congenital myopathy 4B, autosomal recessive; Congenital myopathy with fiber type disproportion | 2022-07-26 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 254 of the TPM3 protein (p.Ile254Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TPM3-related conditions. ClinVar contains an entry for this variant (Variation ID: 531179). 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 C25"). 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. |
