LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism.4[1], 5[2], 6[3]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism.7[1], 8[2]

Ratio Explanation:

This ratio may reflect the balance between sphingolipid and glycerophospholipid synthesis, which is likely modulated by GCKR-regulated hepatic de novo lipogenesis.9[1], 10[2], 11[3]

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

GCKR variants modulate hepatic glucose metabolism and de novo lipogenesis, altering the SM/PC ratio, which is associated with dyslipidemia, liver steatosis (cirrhosis, NAS), and cardiometabolic diseases like T2D and IHD.1[1], 10[2], 12[3], 13[4]

Phenotype Driver:

Gene-centric:GCKR
