Patient data are sorted by mutation combination frequency. | Reference: | Mancuso et al, 2004b; | | Description: | Presented with progressive bilateral ptosis, diplopia, muscle weakness, and exercise intolerance at 28 years of age. Ophthalmoplegia and severe bilateral ptosis developed by age 44, sensory neuropathy at age 45, and at age 47 she developed slowly progressive resting hand tremor, slowing of her gait, bradykinesia, rigidity, and slurred speech. Muscle biopsy showed numerous ragged-red fibers and Southern blot analysis showed multiple deletions of mtDNA. insipient parkinsonism. | | Mutations: | | | SNPs: | Y831C | | Age group: | adult | | Age of Onset: 28, Age of Patient: 49, Age of Death: n/a |
