| Identified Mutation |
(CAG)n EXPANSION; DRPLA is caused by expansion of a trinucleotide repeat (CAG)n. The repeat size varies from 7 to 23 in normal individuals and shows an expansion to approximately 49 to 75 (and occasionally even more) in patients. As with other disorders caused by expanded trinucleotide repeats, expansion is usually associated with paternal transmission. The repeat size correlates inversely with age-of-onset of symptoms and with disease severity. |

| Remarks |
Hyperactivity & short attention span at age 7; at age 8 showed developmental & cognitive regression; significantly demented at age 12; recurrent generalized tonic-clonic seizures; DRPLA CAG expansion repeat alleles are 16 and 68 |
