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]

Variant summary: SETX c.4828C>T (p.Leu1610Phe) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4.8e-05 in 251418 control chromosomes, predominantly at a frequency of 0.00011 within the Non-Finnish European subpopulation in the gnomAD database. This frequency is not significantly higher than estimated for a pathogenic variant in SETX causing Spinocerebellar ataxia, autosomal recessive, with axonal neuropathy 2 (4.8e-05 vs 0.0012), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.4828C>T in individuals affected with Spinocerebellar ataxia, autosomal recessive, with axonal neuropathy 2 and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 574888). Based on the evidence outlined above, the variant was classified as uncertain significance.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.4828C>T (p.L1610F) alteration is located in exon 10 (coding exon 8) of the SETX gene. This alteration results from a C to T substitution at nucleotide position 4828, causing the leucine (L) at amino acid position 1610 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
