LLM Analysis

Numerator Metabolite Explanation:

Fatty acid biosynthesis/metabolism.5[1], 6[2], 7[3], 8[4]

Denominator Metabolite Explanation:

Carnitine shuttle, fatty acid metabolism.9[1], 10[2], 11[3], 12[4]

Ratio Explanation:

The ratio reflects carnitine-dependent fatty acid metabolism; reduced SLC22A5 function can impair acetylcarnitine formation, increasing the ratio of fatty acids to carnitine species.

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Genetic variants in SLC22A5 alter carnitine transport, impacting the EPA/acetylcarnitine ratio and cellular energy metabolism, which plausibly influences immune cell counts and inflammatory phenotypes.13[1], 14[2]

Phenotype Driver:

Gene-centric:SLC22A5
