Further, when we compared mean mRNA expression ratio of VDR/GAPDH between non-reaction (NR) and T1R/T2R groups of leprosy, it was noted that the ratio is not significantly different between the groups (NR vs T1R 0.5894 vs 1.044, p = 0.05; NR vs T2R 0.5894 vs 5.62, p = 0.9529). The gene discussed is GAPDH; the disease is leprosy.
