A potential candidate gene that could contribute to the education process i
s the apolipoprotein E (apo E) gene that has been shown to correlate with m
emory function and memory decline, We measured apo E polymorphism in groups
of probands with different levels of education selected from a population
sample. In the group of probands with higher education (n = 82), 24.4% had
the e4 allele, compared with 7.3% who had the e2 allele, A reverse associat
ion was found in the group that left school aged 15 (n = 36) - 8.3% had the
e4 allele and 13.9% had the e2 allele. Eighty-seven percent of the proband
s with the allele e4 reached higher education, compared to only 54.5% with
the allele e2, The difference between the groups is statistically significa
nt (p = 0.039), and this may indicate some role for the apo E polymorphism
in subjects' intelligence or ability to learn. Copyright (C) 2001 S. Karger
