LLM Analysis

Numerator Metabolite Explanation:

Plasmalogen biosynthesis, Glycerophospholipid metabolism.5[1], 6[2]

Denominator Metabolite Explanation:

Sphingolipid metabolism.7[1], 8[2], 9[3]

Ratio Explanation:

The ratio likely reflects lipoprotein particle composition and overall lipid transport efficiency, which is modulated by the function of APOE and APOC1 proteins.

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Altered APOE/APOC1 function disrupts lipoprotein metabolism, as indicated by the metabolite ratio, contributing to dyslipidemia, a known cause of the associated cardiovascular phenotypes like coronary atherosclerosis and myocardial infarction.3[1], 10[2], 4[3]

Phenotype Driver:

Gene-centric:APOE
