The single- nucleotide polymorphism rs5848 increases the risk of Alzheimers disease AD. We explored the association between alleles of rs5848 and the risk of AD in the Taiwanese population. The frequency of the homozygous TT genotype 16.4 vs. 10.0% increased in AD subjects by an odds ratio OR of 1 .87 p = 0.03 corrected for APOE epsilon 4, age and gender. Interaction between age and homozygous TT genotype accentuated the risk of AD OR 4.44, p < 0.001. The homozygous TT genotype of rs5848 may play a role in the genetic risk of AD development, especially in the elderly.en-USAlzheimers diseaseProgranulinrs5848 gene variantDementiarisk factor
