| Invitae | RCV001343944 | SCV001537964 | uncertain significance | Myofibrillar myopathy 4 | 2024-01-17 | 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.*10676G>C in the primary transcript. This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 411 of the LDB3 protein (p.Val411Leu). This variant also falls at the last nucleotide of exon 9, which is part of the consensus splice site for this exon. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LDB3-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). 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. |
