Phenotypes associated with the disease dilated cardiomyopathy 1C (OMIM:601493):
- Adult onset (HP:0003581): Onset of disease manifestations in adulthood, defined here as at the age of 16 years or later. Evidence: PCS. (PMID:14662268)
- Left ventricular noncompaction (HP:0030682): Left ventricular noncompaction (LVNC) is defined by 3 markers: prominent left ventricular (LV) trabeculae, deep intertrabecular recesses, and the thin compacted layer. Evidence: TAS. Frequency: Occasional (HP:0040283). (OMIM:601493)
- Congestive heart failure (HP:0001635): The presence of an abnormality of cardiac function that is responsible for the failure of the heart to pump blood at a rate that is commensurate with the needs of the tissues or a state in which abnormally elevated filling pressures are required for the heart to do so. Heart failure is frequently related to a defect in myocardial contraction. Evidence: IEA. (OMIM:601493)
- Left ventricular hypertrophy (HP:0001712): Enlargement or increased size of the heart left ventricle. Evidence: PCS. Frequency: 8/13. (PMID:14662268)
- Endocardial fibrosis (HP:0006685): The presence of excessive connective tissue in the endocardium. Evidence: IEA. (OMIM:601493)
- Left bundle branch block (HP:0011713): A conduction block of the left branch of the bundle of His. This manifests as a generalized disturbance of QRS morphology on EKG. Evidence: PCS. Frequency: 1/13. (PMID:14662268)
- Ventricular arrhythmia (HP:0004308). Evidence: IEA. Frequency: Occasional (HP:0040283). (OMIM:601493)
- Increased left ventricular end-diastolic volume (HP:0033755): Abnormally high volume of blood in the left ventricle at the end of diastole (just before systole). Evidence: PCS. Frequency: 10/13. (PMID:14662268)
- Autosomal dominant inheritance (HP:0000006): A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele. Evidence: PCS. (PMID:14662268)
- Sudden cardiac death (HP:0001645): The heart suddenly and unexpectedly stops beating resulting in death within a short time period (generally within 1 h of symptom onset). Evidence: PCS. Frequency: 3/13. (PMID:14662268)
- Dilated cardiomyopathy (HP:0001644): Dilated cardiomyopathy (DCM) is defined by the presence of left ventricular dilatation and left ventricular systolic dysfunction in the absence of abnormal loading conditions (hypertension, valve disease) or coronary artery disease sufficient to cause global systolic impairment. Right ventricular dilation and dysfunction may be present but are not necessary for the diagnosis. Evidence: PCS. Frequency: 13/13. (PMID:14662268)
