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.

The p.Glu139Lys variant in LDB3 has been identified in 1 individual with HCM (L MM, unpublished data) and 1 individual with unknown clinical status (Ng 2013). I t has also been identified in 14/25364 South and East Asian chromosomes by the E xome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Computationa l prediction tools and conservation analysis do not provide strong support for o r against an impact to the protein. In summary, the clinical significance of the p.Glu139Lys variant is uncertain. -

Collection Method:clinical testing

The p.E139K variant (also known as c.415G>A), located in coding exon 5 of the LDB3 gene, results from a G to A substitution at nucleotide position 415. The glutamic acid at codon 139 is replaced by lysine, an amino acid with similar properties. This alteration has been reported as a secondary cardiac variant in an exome cohort (Ng D et al. Circ Cardiovasc Genet. 2013;6:337-46). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
