LLM Analysis

Numerator Metabolite Explanation:

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

Denominator Metabolite Explanation:

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

Ratio Explanation:

This ratio reflects the balance of different sphingomyelin species. ISM1's role in lipid metabolism suggests it may influence the synthesis or turnover of these lipids.

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

ISM1 dysregulation alters lipid metabolism, including sphingomyelins and cholesterol. This metabolic shift is linked to increased LDL cholesterol and a higher risk of cholelithiasis (gallstones).7[1], 8[2], 9[3], 10[4]

Phenotype Driver:

Gene-centric:ISM1
