Abstract

We have previously described linkage/association between reelin gene polymorphisms and autistic disorder. APOE also participates in the Reelin signaling pathway, by competitively antagonizing Reelin binding to APOE receptor 2 and to very-low-density lipoprotein receptors. The APOE2 protein variant displays the lowest receptor binding affinity compared with APOE3 and APOE4. In this study, we assess linkage/association between primary autism and APOE alleles in 223 complete trios, from 119 simplex Italian families and 44 simplex and 29 multiplex Caucasian-American families. Statistically significant disequilibrium favors the transmission of ε2 alleles to autistic offspring, over ε3 and ε4 (allele-wise transmission/ disequilibrium test [TDT], χ2 = 6.16, 2 degrees of freedom [d.f.], P2 = 10.68, 3 d.f., P2 = 1.83, 2 d.f., P
