LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism.4[1], 5[2]

Denominator Metabolite Explanation:

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

Ratio Explanation:

An elevated ratio suggests FADS1 activity may favor sphingolipid pathways over plasmalogen synthesis, potentially impacting membrane composition and downstream signaling.6[1], 4[2], 8[3]

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Reduced FADS1 activity, indicated by the altered metabolite ratio, is linked to an increased risk of cholelithiasis and type 2 diabetes.9[1], 10[2], 11[3], 12[4], 13[5] This may be due to altered lipid mediator balance, impacting inflammation and metabolic processes.11[6]

Phenotype Driver:

Gene-centric:FADS1
