Conditional analysis results show that rs2078371 is driving the differential expression results for both TSPAN2 and NGF, as when conditioned on rs2078371, the differential expression p values for these genes drop from 1.95 × 10–13 to 0.674 and 9.35 × 10–8 to 0.839, respectively (i.e., they were no longer significantly differentially expressed with migraine). The gene discussed is NGF; the disease is migraine disorder.
