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]

The p.S761L variant (also known as c.2282C>T), located in coding exon 8 of the SETX gene, results from a C to T substitution at nucleotide position 2282. The serine at codon 761 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the supporting evidence, this variant is unlikely to be causative of juvenile amyotrophic lateral sclerosis 4; however, its contribution to the development of spinocerebellar ataxia with axonal neuropathy 2 is uncertain. -
