LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism

Denominator Metabolite Explanation:

Glycerophospholipid metabolism

Ratio Explanation:

This ratio reflects the balance between sphingomyelin, a key component of cell membranes and lipoproteins, and a specific phosphatidylcholine, indicating potential shifts in lipid metabolism.4[1], 5[2]

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Lower APOA1 levels are associated with reduced HDL, impaired cholesterol efflux, and an increased risk of cardiovascular diseases, including atherosclerosis, myocardial infarction, and hypercholesterolemia.1[1], 6[2], 7[3], 8[4] The altered sphingomyelin to phosphatidylcholine ratio may reflect dysregulated lipid metabolism contributing to these conditions.

Phenotype Driver:

Gene-centric:APOA1
