Ambry Genetics RCV002421591 SCV002718088 uncertain significance Cardiovascular phenotype 2020-01-24 criteria provided, single submitter clinical testing The p.D652H variant (also known as c.1954G>C), located in coding exon 11 of the LDB3 gene, results from a G to C substitution at nucleotide position 1954. The aspartic acid at codon 652 is replaced by histidine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. 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.
Invitae RCV003097382 SCV003220459 uncertain significance Myofibrillar myopathy 4 2022-07-11 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. 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 (rs753145429, gnomAD 0.007%). This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 652 of the LDB3 protein (p.Asp652His). The LDB3 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_007078.3, and corresponds to NM_001080116.1: c.*19449G>C in the primary transcript.
