LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism, Phosphatidylcholine biosynthesis6[1], 7[2], 8[3], 9[4]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism, Phospholipid Metabolism7[1], 10[2], 11[3]

Ratio Explanation:

This ratio reflects the balance between two types of phosphatidylcholines, with the FADS1/FADS2 genes being pivotal in the synthesis of the long-chain fatty acids they contain.1[1], 2[2], 3[3], 12[4]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Variants in the FADS1/FADS2 gene cluster alter the efficiency of PUFA synthesis, which can influence lipid profiles, including cholesterol levels, and are associated with an increased risk for pure hypercholesterolemia.13[1], 14[2], 15[3], 16[4] This altered lipid metabolism may also contribute to inflammatory conditions like asthma.13[5], 17[6]

Phenotype Driver:

Gene-centric:FADS1/FADS2
