Similar results were obtained for TYMS 28-bp tandem repeat (rs34743033), where the 3R/3R genotype was associated with a protective effect against HNSCC development when comparing the C group by the recessive model (OR = 0.51; 95% CI = 0.30–0.85; p = 0.009). The gene discussed is TYMS; the disease is head and neck squamous cell carcinoma.
