Dilated cardiomyopathy 1E- MedGen UID:
- 331341
- •Concept ID:
- C1832680
- •
- Disease or Syndrome
Any familial isolated dilated cardiomyopathy in which the cause of the disease is a mutation in the SCN5A gene.
Hypertrophic cardiomyopathy 10- MedGen UID:
- 331754
- •Concept ID:
- C1834460
- •
- Disease or Syndrome
Any hypertrophic cardiomyopathy in which the cause of the disease is a mutation in the MYL2 gene.
Scalp-ear-nipple syndrome- MedGen UID:
- 357183
- •Concept ID:
- C1867020
- •
- Disease or Syndrome
Scalp-ear-nipple syndrome is characterized by aplasia cutis congenita of the scalp, breast anomalies that range from hypothelia or athelia to amastia, and minor anomalies of the external ears. Less frequent clinical characteristics include nail dystrophy, dental anomalies, cutaneous syndactyly of the digits, and renal malformations. Penetrance appears to be high, although there is substantial variable expressivity within families (Marneros et al., 2013).
Dilated cardiomyopathy 1AA- MedGen UID:
- 393713
- •Concept ID:
- C2677338
- •
- Disease or Syndrome
Any familial isolated dilated cardiomyopathy in which the cause of the disease is a mutation in the ACTN2 gene.
Ogden syndrome- MedGen UID:
- 477078
- •Concept ID:
- C3275447
- •
- Disease or Syndrome
Ogden syndrome (OGDNS) is an X-linked neurodevelopmental disorder characterized by postnatal growth failure, severely delayed psychomotor development, variable dysmorphic features, and hypotonia. Many patients also have cardiac malformations or arrhythmias (summary by Popp et al., 2015).
Atrial fibrillation, familial, 15- MedGen UID:
- 862706
- •Concept ID:
- C4014269
- •
- Disease or Syndrome
Atrial fibrillation (AF) is a supraventricular tachyarrhythmia characterized by uncoordinated atrial activation with consequent deterioration of atrial mechanical function. It is the most common sustained cardiac rhythm disturbance, and its prevalence increases as the population ages. An estimated 70,000 strokes each year are caused by atrial fibrillation (summary by Oberti et al., 2004).

Myopathy with abnormal lipid metabolism- MedGen UID:
- 934789
- •Concept ID:
- C4310822
- •
- Disease or Syndrome
Lipid storage myopathy due to FLAD1 deficiency is an autosomal recessive inborn error of metabolism that includes variable mitochondrial dysfunction. The phenotype is extremely heterogeneous: some patients have a severe disorder with onset in infancy and cardiac and respiratory insufficiency resulting in early death, whereas others have a milder course with onset of muscle weakness in adulthood. Some patients show significant improvement with riboflavin treatment (summary by Olsen et al., 2016).
Cardiomyopathy, dilated, 2I- MedGen UID:
- 1841321
- •Concept ID:
- C5830685
- •
- Disease or Syndrome
Dilated cardiomyopathy-2I (CMD2I) is characterized by early-onset severe congestive heart failure. Some patients experience supraventricular tachycardia. Structural heart defects and nemaline bodies in cardiac and skeletal muscle have been observed (Aspit et al., 2019; Cheema et al., 2020; Gurunathan et al., 2022).
