SETX(redirected from amyotrophic lateral sclerosis 4)
SETXA gene on chromosome 9q34 that encodes a protein homolous to fungal Sen1p protein which has RNA helicase activity, and which is thought to be involved in RNA and DNA processing and repairing breaks in double-stranded DNA caused by oxidative damage.
SETX mutations have been linked to ataxia-ocular apraxia-2 (AOA2) and an autosomal dominant form of juvenile amyotrophic lateral sclerosis (ALS4).
