Labcorp Genetics (formerly Invitae), Labcorp RCV000700421 SCV000829175 uncertain significance Myofibrillar myopathy 4 2024-11-11 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 263 of the LDB3 protein (p.Arg263Cys). This variant is present in population databases (rs377201153, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with LDB3-related conditions. ClinVar contains an entry for this variant (Variation ID: 198762). 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 disruptive. 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.
GeneDx RCV000180202 SCV001993454 uncertain significance not provided 2019-08-12 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar as a variant of uncertain significance but additional evidence is not available (ClinVar Variant ID# 198762; Landrum et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function
PreventionGenetics, part of Exact Sciences RCV004742318 SCV005353313 uncertain significance LDB3-related disorder 2024-08-14 no assertion criteria provided clinical testing The LDB3 c.928C>T variant is predicted to result in the amino acid substitution p.Arg310Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0051% of alleles in individuals of East Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
