NOD2 and thyroid cancer, nonmedullary, 2: Among the identified NOD2 rs2066842 SNPs, differentiated PTC from FTC and the c.802 T allele were more common in patients with follicular thyroid cancer than in patients with papillary thyroid cancer (additive model: p = 0.02, OR = 1.65 ± SE 0.40–2.89; dominant model: p = 0.031, OR = 2.00 ± SE 0.62–3.38).
