LLM Analysis

Numerator Metabolite Explanation:

Phosphatidylcholine biosynthesis, glycerophospholipid metabolism.3[1], 4[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism, fatty acid metabolism.5[1], 6[2]

Ratio Explanation:

The ratio reflects FADS gene cluster activity, comparing a phosphatidylcholine with DHA (22:6) to a lysophosphatidylcholine with linoleic acid (18:2), a precursor.1[1], 7[2], 8[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Variants in the FADS gene cluster alter the efficiency of fatty acid desaturation, influencing the balance of omega-3 and omega-6 fatty acids.9[1], 7[2] This dysregulation is linked to altered blood lipid profiles, including cholesterol, connecting the gene to the 'Pure hypercholesterolaemia' phenotype.10[3], 11[4]

Phenotype Driver:

Gene-centric:FADS1/FADS2
