LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism.4[1]

Denominator Metabolite Explanation:

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

Ratio Explanation:

An elevated ratio may indicate a shift from de novo sphingomyelin synthesis to other pathways, potentially influenced by ESR2's role in lipid metabolism.

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

ESR2's role in regulating lipid metabolism and adipocyte differentiation likely influences sphingolipid pathways, contributing to dyslipidemia, a phenotype characterized by abnormal lipid levels, including triglycerides.1[1], 2[2], 3[3], 7[4] This alteration in sphingolipid metabolism is also linked to changes in HbA1c.8[5], 9[6], 10[7]

Phenotype Driver:

Gene-centric:ESR2
