LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism, Omega-3 fatty acid metabolism.3[1], 4[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism, Omega-6 fatty acid metabolism.5[1]

Ratio Explanation:

The ratio reflects FADS enzyme activity, comparing a downstream product (DHA, 22:6) to a precursor (linoleic acid, 18:2) in polyunsaturated fatty acid synthesis.6[1], 7[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

FADS1/FADS2 variants alter polyunsaturated fatty acid synthesis, affecting the balance of pro- and anti-inflammatory molecules.8[1], 9[2] This dysregulation is linked to inflammatory and metabolic conditions like cholelithiasis, type 2 diabetes, and hypercholesterolemia, which are common among the associated phenotypes.9[3], 10[4], 11[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
