As an example, enrichment analysis on the first 100 genes returned by the "Obesity" query linked this disease to biological processes such as "fat cell differentiation" (20 genes, multiple-test adjusted enrichment p-value (adjp) = 5.27e-28), "lipid metabolic process" (39 genes, adjp = 5.05e-20) and "response to insulin stimulus" (17 genes, adjp = 4.99e-18). The gene discussed is INS; the disease is obesity due to melanocortin 4 receptor deficiency.
