LLM Analysis

Numerator Metabolite Explanation:

Fatty acid metabolism/oxidation, Carnitine shuttle.3[1], 4[2]

Denominator Metabolite Explanation:

Fatty acid omega-oxidation.5[1]

Ratio Explanation:

Increased stearoylcarnitine, a saturated acylcarnitine, relative to decadienedioic acid suggests altered fatty acid metabolism, potentially reflecting decreased SCD activity and subsequent shunting toward omega-oxidation.

Ratio Evidence:

metabolites not in a pathway but enzyme catalyzes one metabolite

Gene Ratio Phenotype Relationship:

Reduced SCD activity is associated with hypercholesterolemia and coronary artery disease.6[1], 7[2], 8[3] The elevated ratio of stearoylcarnitine to decadienedioic acid may reflect this decreased desaturase activity, providing a metabolic link to the observed cardiovascular phenotypes.

Phenotype Driver:

Gene-centric:SCD
