LLM Analysis

Numerator Metabolite Explanation:

Ether lipid (plasmalogen) synthesis.4[1], 5[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism, PUFA synthesis.6[1], 7[2]

Ratio Explanation:

This ratio reflects the balance between ether lipid synthesis incorporating saturated fatty acids and phospholipid synthesis incorporating polyunsaturated fatty acids, modulated by FADS activity.

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

FADS1/FADS2 gene variants alter desaturase activity, affecting the balance of saturated ether lipids to polyunsaturated phospholipids.1[1], 8[2] This imbalance in lipid metabolism is associated with an increased risk for hypercholesterolemia, cholelithiasis, and inflammatory conditions like phlebitis and pulmonary embolism.9[3], 10[4], 11[5], 12[6]

Phenotype Driver:

Gene-centric:FADS1/FADS2
