LLM Analysis

Numerator Metabolite Explanation:

Omega-3 fatty acid metabolism.3[1]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism.4[1]

Ratio Explanation:

The ratio reflects the efficiency of FADS-mediated conversion of fatty acid precursors into long-chain polyunsaturated fatty acids like eicosapentaenoate (EPA).3[1], 2[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in the FADS cluster alters the balance of pro- and anti-inflammatory polyunsaturated fatty acids.5[1], 6[2] This dysregulation of lipid metabolism and inflammation is linked to associated phenotypes like cholelithiasis, hypercholesterolemia, and inflammatory conditions such as asthma and dermatitis.5[3], 7[4], 1[5], 8[6]

Phenotype Driver:

Gene-centric:FADS1/FADS2
