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 c.3968G>A (p.R1323Q) alteration is located in exon 10 (coding exon 8) of the SETX gene. This alteration results from a G to A substitution at nucleotide position 3968, causing the arginine (R) at amino acid position 1323 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The SETX c.3968G>A variant is predicted to result in the amino acid substitution p.Arg1323Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.025% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/9-135203017-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
