Cardiomyopathy, Dilated, 1c, with or Without Left Ventricular Noncompaction, also known as left ventricular noncompaction 3, is related to cardiomyopathy, dilated, 1a and late-onset distal myopathy, markesbery-griggs type. An important gene associated with Cardiomyopathy, Dilated, 1c, with or Without Left Ventricular Noncompaction is LDB3 (LIM Domain Binding 3), and among its related pathways/superpathways are Immunoregulatory interactions between a Lymphoid and a non-Lymphoid cell and Hematopoietic Stem Cells and Lineage-specific Markers. Affiliated tissues include heart and heart-ventricle, and related phenotypes are ventricular arrhythmia and left ventricular noncompaction
