DiseaseLDB3_HUMAN Defects in LDB3 are the cause of cardiomyopathy dilated type 1C (CMD1C) [MIM:601493. Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death.[1] [2] Defects in LDB3 are the cause of left ventricular non-compaction type 3 (LVNC3) [MIM:601493. Left ventricular non-compaction is characterized by numerous prominent trabeculations and deep intertrabecular recesses in hypertrophied and hypokinetic segments of the left ventricle. Defects in LDB3 are the cause of myopathy myofibrillar type 4 (MFM4) [MIM:609452.
