Genes affected
LDB3 (HGNC:15710): (LIM domain binding 3) This gene encodes a PDZ domain-containing protein. PDZ motifs are modular protein-protein interaction domains consisting of 80-120 amino acid residues. PDZ domain-containing proteins interact with each other in cytoskeletal assembly or with other proteins involved in targeting and clustering of membrane proteins. The protein encoded by this gene interacts with alpha-actinin-2 through its N-terminal PDZ domain and with protein kinase C via its C-terminal LIM domains. The LIM domain is a cysteine-rich motif defined by 50-60 amino acids containing two zinc-binding modules. This protein also interacts with all three members of the myozenin family. Mutations in this gene have been associated with myofibrillar myopathy and dilated cardiomyopathy. Alternatively spliced transcript variants encoding different isoforms have been identified; all isoforms have N-terminal PDZ domains while only longer isoforms (1, 2 and 5) have C-terminal LIM domains.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 08, 2022 | 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 (rs773235586, gnomAD 0.003%). This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 702 of the LDB3 protein (p.Val702Leu). The LDB3 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_007078.3, and corresponds to NM_001080116.1:c.*33522G>T in the primary transcript. - |
