| Disease ID | Source | Name | Description |
| 617069 | OMIM | Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal recessive 3 (PEOB3) | A form of progressive external ophthalmoplegia, a mitochondrial myopathy characterized by progressive paralysis of the levator palpebrae, orbicularis oculi, and extraocular muscles. PEOB3 patients manifest adult-onset progressive external ophthalmoplegia and progressive proximal muscle weakness associated with muscle atrophy. The disease is caused by variants affecting the gene represented in this entry. |
| 609560 | OMIM | Mitochondrial DNA depletion syndrome 2 (MTDPS2) | A disorder due to mitochondrial dysfunction characterized by childhood onset of muscle weakness associated with depletion of mtDNA in skeletal muscle. There is wide clinical variability; some patients have onset in infancy and show a rapidly progressive course with early death due to respiratory failure, whereas others have later onset of a slowly progressive myopathy. The disease is caused by variants affecting the gene represented in this entry. |
