Summaries for LDB3 Gene

Entrez Gene Summary for LDB3 Gene

  • 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.

  • Cardiomyopathy, dilated 1C, with or without left ventricular non-compaction (CMD1C) [MIM:601493]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. Cardiomyopathy dilated type 1C is associated with left ventricular non-compaction in some patients. Left ventricular non-compaction is characterized by numerous prominent trabeculations and deep intertrabecular recesses in hypertrophied and hypokinetic segments of the left ventricle. {ECO:0000269 PubMed:14660611, ECO:0000269 PubMed:14662268}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Left ventricular non-compaction 3 (LVNC3) [MIM:601493]: A form of left ventricular non-compaction, a cardiomyopathy due to myocardial morphogenesis arrest and characterized by a hypertrophic left ventricle, a severely thickened 2-layered myocardium, numerous prominent trabeculations, deep intertrabecular recesses, and poor systolic function. Clinical manifestations are variable. Some affected individuals experience no symptoms at all, others develop heart failure. In some cases, left ventricular non-compaction is associated with other congenital heart anomalies. LVNC3 is an autosomal dominant condition. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Myopathy, myofibrillar, 4 (MFM4) [MIM:609452]: A form of myofibrillar myopathy, a group of chronic neuromuscular disorders characterized at ultrastructural level by disintegration of the sarcomeric Z disk and myofibrils, and replacement of the normal myofibrillar markings by small dense granules, or larger hyaline masses, or amorphous material. MFM4 is characterized by distal and proximal muscle weakness with signs of cardiomyopathy and neuropathy. Note=The disease is caused by mutations affecting the gene represented in this entry.
