Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 1P and 4B. PP3 BS1

The NM_015046.7(SETX):​c.1391C>T​(p.Ser464Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00048 in 1,572,286 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely benign in ClinVar. Synonymous variant affecting the same amino acid position (i.e. S464S) has been classified as Likely benign.

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]

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.776
• BS1: Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.00051 (724/1420108) while in subpopulation NFE AF = 0.00065 (709/1090982). AF 95% confidence interval is 0.00061. There are 0 homozygotes in GnomAdExome4. There are 359 alleles in the male GnomAdExome4 subpopulation. Median coverage is 35. This position passed quality control check.
