Genes affected
SETX (HGNC:445): (senataxin) This gene encodes a protein named for its homology to the Sen1p protein of fungi which has RNA helicase activity encoded by a domain at the C-terminal end of the protein. The protein encoded by this gene contains a DNA/RNA helicase domain at its C-terminal end which suggests that it may be involved in both DNA and RNA processing. Mutations in this gene have been associated with ataxia-ocular apraxia-2 (AOA2) and an autosomal dominant form of juvenile amyotrophic lateral sclerosis (ALS4). [provided by RefSeq, Jul 2008]

In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Observed in apparent homozygous state in two siblings with ataxia with peripheral neuropathy and increased serum AFP in published literature; however the affected siblings were also apparently homozygous for another SETX variant and unaffected siblings were heterozygous for both SETX variants (Asaka et al., 2006); This variant is associated with the following publications: (PMID: 23566282, 23129421, 16717225) -
