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]

Submissions by phenotype
SETX-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Feb 07, 2023 | The SETX c.93A>G variant is not predicted to result in an amino acid change (p.=). This variant is predicted to generate a cryptic splice acceptor site within exon 3 (Alamut Visual Plus v1.6.1); however, in silico predictions are imperfect and not equivalent to functional evidence. To our knowledge, this variant has not been reported in the literature. It is reported in 0.0080% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/9-135224723-T-C). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. - |
Inborn genetic diseases Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 11, 2019 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
