GeneDx RCV001772620 SCV001993199 uncertain significance not provided 2019-08-14 criteria provided, single submitter clinical testing Not observed in large population cohorts (Lek et al., 2016); The majority of missense variants in this gene are considered pathogenic (Stenson et al., 2014); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Has not been previously published as pathogenic or benign to our knowledge
Labcorp Genetics (formerly Invitae), Labcorp RCV003514520 SCV004296044 uncertain significance Arthrogryposis, distal, type 1A 2023-07-03 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 1307765). This variant has not been reported in the literature in individuals affected with TPM2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 189 of the TPM2 protein (p.Lys189Glu).
