The prevalence of the HLA A2 allele was investigated in a group of Italian patients with sporadic and early‐onset familial Alzheimer's disease (AD and FAD) to analyze the potential association of this allele with early age of onset of the disease. The possible interaction between the HLA A2 allele and apolipoprotein E ε4 allele was analyzed. Our data suggest that A2 and ε4 alleles may have additive effects on AD onset, and that A2 may play an important role in determining or contributing to a very early age at onset. These findings further support the hypothesis of the involvement of an immune/inflammatory mechanism in the pathogenesis of AD. Ann Neurol 1999;45:397–400
