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.G1006R variant (also known as c.3016G>A), located in coding exon 8 of the SETX gene, results from a G to A substitution at nucleotide position 3016. The glycine at codon 1006 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species, and arginine is the reference amino acid in other vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the supporting evidence, this variant is unlikely to be causative of juvenile amyotrophic lateral sclerosis 4 (ALS4); however, its contribution to the development of spinocerebellar ataxia with axonal neuropathy 2 (SCAN2) is uncertain. -
