Genes affected

AOX1 (HGNC:553): (aldehyde oxidase 1) Aldehyde oxidase produces hydrogen peroxide and, under certain conditions, can catalyze the formation of superoxide. Aldehyde oxidase is a candidate gene for amyotrophic lateral sclerosis. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.758

Collection Method: clinical testing

The c.1135C>T (p.L379F) alteration is located in exon 12 (coding exon 12) of the AOX1 gene. This alteration results from a C to T substitution at nucleotide position 1135, causing the leucine (L) at amino acid position 379 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
