GeneDx RCV001583028 SCV001813445 likely benign not provided 2020-01-08 criteria provided, single submitter clinical testing 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
Labcorp Genetics (formerly Invitae), Labcorp RCV001583028 SCV002239286 uncertain significance not provided 2024-11-11 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 234 of the DIAPH3 protein (p.Ile234Thr). This variant is present in population databases (rs200839105, gnomAD 0.08%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with DIAPH3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1210950). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The threonine 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.
