Ataxia-ocular apraxia 2 (AOA2) was recently identified as a new autosomal
recessive ataxia. We have now identified causative mutations in 15 families,
which allows us to clinically define this entity by onset between 10 and 22
years, cerebellar atrophy, axonal sensorimotor neuropathy, oculomotor apraxia and
elevated alpha-fetoprotein (AFP). Ten of the fifteen mutations cause premature
termination of a large DEAxQ-box helicase, the human ortholog of yeast Sen1p,
involved in RNA maturation and termination.
