Submissions by phenotype
not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | May 11, 2021 | Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge - |
Charcot-Marie-Tooth disease type 4 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 27, 2021 | This sequence change replaces serine with asparagine at codon 30 of the SH3TC2 protein (p.Ser30Asn). The serine residue is weakly conserved and there is a small physicochemical difference between serine and asparagine. This variant is present in population databases (rs765890403, ExAC 0.004%). This variant has not been reported in the literature in individuals affected with SH3TC2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The asparagine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. - |
