An association study was performed between apolipoprotein E (apoE) polymorphism and the common structural polymorphism Glu/Asp at codon 298 of the nitric oxide synthase (NOS3) gene in late-onset sporadic Alzheimer's dementia probands (LOAD), diffuse Lewy body dementia cases (DLBD) and controls in a Hungarian sample. The frequency of individuals who carried the apoE epsilon4 allele was significantly more common in both dementia groups (LOAD, 20%; DLBD, 27%; control, 8%; control versus DLBD, chi2=13.264, degrees of freedom=2, P<0.001; control versus LOAD, chi2=6.628, degrees of freedom=2, P<0.036). However, there were no significant differences in the NOS3 genotype and allele distributions between the LOAD, DLBD and control groups. The apoE status has been found to be independent from the NOS3 codon 298 polymorphism in the examined cohort. Despite the facts that NOS3 is associated with neuritic sprouting, and aberrant neuronal and glial expression of the same molecule has been found in neurodegenerative diseases, it is unlikely that the polymorphism Glu/Asp of the NOS3 gene is involved in the development of LOAD and DLBD.
