Table 3

Genotype and allele frequencies of the Asp905Tyr polymorphism of regulatory subunit 3 of protein phosphatase 1 (PPP1R3) resulting from the 2713-G/T base substitution in 202 patients with AD and 160 age matched controls for the total population and after stratification by apolipoprotein E ε4 allele. Results from logistic regression analysis are also presented
