Ambry Genetics RCV002401842 SCV002711850 uncertain significance Cardiovascular phenotype 2022-05-07 criteria provided, single submitter clinical testing The p.E591G variant (also known as c.1772A>G), located in coding exon 10 of the LDB3 gene, results from an A to G substitution at nucleotide position 1772. The glutamic acid at codon 591 is replaced by glycine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
GeneDx RCV003318723 SCV004022878 uncertain significance not provided 2023-01-23 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); 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
Invitae RCV003611610 SCV004519553 uncertain significance Myofibrillar myopathy 4 2023-04-18 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 591 of the LDB3 protein (p.Glu591Gly). 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with LDB3-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.1%). The LDB3 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_007078.3, and corresponds to NM_001080116.1:c.*18685A>G in the primary transcript.
