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]

Spinocerebellar ataxia, autosomal recessive, with axonal neuropathy 2;C1865409:Amyotrophic lateral sclerosis type 4 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJul 19, 2021This sequence change replaces glutamine with glutamic acid at codon 1349 of the SETX protein (p.Gln1349Glu). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and glutamic acid. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with SETX-related disease. This variant is not present in population databases (ExAC no frequency). -
