| A467T2
| developed progressive blepharoptosis at the age of 20 and ophthalmoplegia during subsequent years, at 35, the patient developed progressive unsteadiness of gait. She noted fatigue, myalgia and cramps, which were triggered by moderate exercise. At 44, restless legs syndrome, deficits in memory and concentration, and suffered from recurrent episodes of depression, at 46 showed bilateral blepharoptosis, limited eye movements in all directions except downwards, lateral rotatory nystagmus and slight upbeat nystagmus in upward gaze, but no saccades. She had facial muscle weakness, dysarthria and slight proximal muscle weakness. She had glove and stockinglike hypoesthesia, distally impaired vibration sense, absent ankle reflexes and weak other tendon reflexes, as well as mild dysmetria. Her gait was broad-based, with further impairment with eyes closed. Tandem gait was impaired. deltoid muscle showed myopathic features, structurally abnormal mitochondria with para-crystalline inclusions, | | | 20 | 46 | n/a | Luoma et al, 2005; [view data] | | 507 | R627Q5
