LLM Analysis

Numerator Metabolite Explanation:

Fatty acid omega-oxidation.4[1], 5[2]

Denominator Metabolite Explanation:

Fatty acid biosynthesis and metabolism.6[1], 7[2]

Ratio Explanation:

An increased ratio suggests enhanced omega-oxidation creating octadecanedioate relative to available eicosenoate, an effect potentially driven by altered CYP4F2 activity.4[1], 3[2]

Ratio Evidence:

metabolites not in a pathway but enzyme catalyzes one metabolite

Gene Ratio Phenotype Relationship:

The CYP4F2 variant likely alters fatty acid and eicosanoid metabolism, including this ratio, contributing to the pro-inflammatory and vasoconstrictive states that underlie coronary atherosclerosis and ischemic heart disease.8[1], 9[2], 10[3]

Phenotype Driver:

Gene-centric:CYP4F2
