Abstract | BACKGROUND: OBJECTIVE: A case-control study was performed to further explore the possible involvement of the STH Q7R polymorphism and the extended TAU haplotype in AD, FTD or PD. METHODS: Patients with AD (n = 398), FTD (n = 96) and PD (n = 105), and controls (n = 186) were genotyped for the STH polymorphism and/or the TAU haplotype. Genotype data were related to levels of total-tau, phospho-tau and Abeta(1-42) in cerebral spinal fluid (CSF) in more than 300 AD patients and to an amount of senile plaques and neurofibrillary tangles in the frontal cortex and hippocampus in patients with autopsy-confirmed AD. RESULTS: The STH Q7R polymorphism and the TAU haplotype were in complete linkage disequilibrium in all patients (AD and FTD) and controls investigated for both genes. There were no significant differences in genotype or allele distributions in AD, FTD or PD cases compared to controls. Neither TAU haplotype nor STH influenced CSF levels of total-tau, phospho-tau and Abeta(1-42) significantly. In AD patients with neuropathological scores of plaque and tangles, no associations with TAU haplotype and STH were found. CONCLUSION: We found no evidence that could support a major pathogenic role of STH and TAU haplotype in AD, FTD or PD.
