| Disease ID | Source | Name | Description |
| 613642 | OMIM | Cardiomyopathy, dilated 1GG (CMD1GG) | A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. The disease is caused by variants affecting the gene represented in this entry. |
| 252011 | OMIM | Mitochondrial complex II deficiency, nuclear type 1 (MC2DN1) | A disorder of the mitochondrial respiratory chain with heterogeneous clinical manifestations. Clinical features include psychomotor regression in infants, poor growth with lack of speech development, severe spastic quadriplegia, dystonia, progressive leukoencephalopathy, muscle weakness, exercise intolerance, cardiomyopathy. Some patients manifest Leigh syndrome or Kearns-Sayre syndrome. MC2DN1 inheritance is autosomal recessive. The disease is caused by variants affecting the gene represented in this entry. |
| 256000 | OMIM | Leigh syndrome (LS) | An early-onset progressive neurodegenerative disorder characterized by the presence of focal, bilateral lesions in one or more areas of the central nervous system including the brainstem, thalamus, basal ganglia, cerebellum and spinal cord. Clinical features depend on which areas of the central nervous system are involved and include subacute onset of psychomotor retardation, hypotonia, ataxia, weakness, vision loss, eye movement abnormalities, seizures, and dysphagia. The disease is caused by variants affecting the gene represented in this entry. |
| 614165 | OMIM | Paragangliomas 5 (PGL5) | A neural crest tumor usually derived from the chromoreceptor tissue of a paraganglion. Paragangliomas can develop at various body sites, including the head, neck, thorax and abdomen. Most commonly, they are located in the head and neck region, specifically at the carotid bifurcation, the jugular foramen, the vagal nerve, and in the middle ear. The disease is caused by variants affecting the gene represented in this entry. |
