What condition is associated with ACADS p.Ser193= (c.579G>A)?

ACADS p.Ser193= (c.579G>A) is associated with short chain acyl-CoA dehydrogenase deficiency (ClinVar).

How common is ACADS p.Ser193= (c.579G>A) in the general population?

ACADS p.Ser193= (c.579G>A) is ultra-rare (popmax 0.0165%, mid) (gnomAD).

How is Short chain acyl-CoA dehydrogenase 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.
