Submissions by phenotype
not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 08, 2022 | This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 63 of the CTU2 protein (p.Leu63Val). This variant has not been reported in the literature in individuals affected with CTU2-related conditions. 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: "Not Available"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Not Available"). 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. - |
