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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

c.897-14T>C in intron 6 of LDB3: This variant is not expected to have clinical s ignificance because a T>C change at this position does not diverge from the spli ce consensus sequence and is therefore unlikely to impact splicing. It has also been identified in 9/64996 of European chromosomes by the Exome Aggregation Cons ortium (ExAC, http://exac.broadinstitute.org). -
