However, the results regarding the association of TNF rs1800629 with biomarker levels differ among studies: TNF rs1800629 was previously associated with AD CSF Aβ42 and P-tau231 in some studies [61,62], while no association was observed in other studies [60,102], similarly to our results, suggesting further studies are needed to evaluate the association of this polymorphism with AD biomarkers. The gene discussed is TNF; the disease is Alzheimer disease.
