We identified three KEGG pathways enriched in the set of genes that are co-expressed with TAAR1 in CTC, for which the enrichment core (the leading subset of genes that contribute most to the enrichment score) includes cytochromes, i.e., “Oxidative phosphorylation”, “Diabetic cardiomyopathy”, and “Prion diseases”. The gene discussed is TAAR1; the disease is prion disease.
