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.F458L variant (also known as c.1374T>G), located in coding exon 8 of the SETX gene, results from a T to G substitution at nucleotide position 1374. The phenylalanine at codon 458 is replaced by leucine, an amino acid with highly similar properties. This variant has been previously reported in one ALS patient; however, other clinical or variant details have not been provided (Müller K et al. J. Neurol. Neurosurg. Psychiatry, 2018 Aug;89:817-827). 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 autosomal dominant juvenile amyotrophic lateral sclerosis 4 (ALS4); however, its contribution to the development of autosomal recessive spinocerebellar ataxia with axonal neuropathy 2 (SCAN2) is uncertain. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
