Additionally, the association of the missense variant p.Gly209Ser (rs1799958) in ACADS (Fig. 5b) to ethylmalonate levels (concurrently reported15) is of clinical implication due to the association of the mutated allele with mild SCAD deficiency (MIM: 606885.0007). The gene discussed is ACADS; the disease is short chain acyl-CoA dehydrogenase deficiency.
