Labcorp Genetics (formerly Invitae), Labcorp RCV000639876 SCV000761459 uncertain significance Myofibrillar myopathy 4 2023-12-14 criteria provided, single submitter clinical testing The LDB3 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_007078.3, and corresponds to NM_001080116.1:c.*17361G>A in the primary transcript. This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 547 of the LDB3 protein (p.Arg547Gln). This variant is present in population databases (rs201968826, gnomAD 0.01%). This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (PMID: 36452351). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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 RCV002284414 SCV002574181 uncertain significance not provided 2022-03-16 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
