What condition is associated with ACOX1 p.Ala117= (c.351G>A)?

ACOX1 p.Ala117= (c.351G>A) is associated with peroxisomal acyl-CoA oxidase deficiency (ClinVar).

How common is ACOX1 p.Ala117= (c.351G>A) in the general population?

ACOX1 p.Ala117= (c.351G>A) is very rare (popmax 0.00659%, sas) (gnomAD).

How is Peroxisomal acyl-CoA oxidase deficiency inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
