Table 1.

ApoE genotype and allele frequencies for patients with AD, bvFTD, and healthy controls

Subjects ApoE genotype
Allele frequency, %
ε4 carriers, %
ε2/ε2 ε2/ε3 ε2/ε4 ε3/ε3 ε3/ε4 ε4/ε4 ε2 ε3 ε4
AD (51 subjects) 0 1* 0 20* 26** 4** 1.0* 65.7 33.3** 58.8
bvFTD (31 subjects) 0 3 0 20 8 0 4.8 82.3 12.9 25.8
Controls (56 subjects) 1 10 2 35 8 0 12.5 78.6 8.9 17.9

Differences among the groups in apoE genotypes and allele frequencies were tested by using the Pearson χ2 test.

*Significantly lower than controls (P < 0.05).

**Significantly higher than controls (P < 0.05).
