Table 3.
Distribution of genotype and allele frequencies of −1082 (G/A) SNP in MCIs that remain stable, progressed to AD (MCI→AD), and progressed to VD (MCI→VD).
| GG (H) | GA (M) | AA (L) | G | A | |
|---|---|---|---|---|---|
| MCI stable | 8 (28.6%) | 12 (42.8%) | 8 (28.6%) | 28 (50%) | 28 (50%) |
| MCI→AD | 2 (8.3%) | 12 (50%) | 10 (41.7%) | 16 (33.3%) | 32 (66.7%) |
| MCI→VD | 5 (22.7%) | 11 (50%) | 6 (27.3%) | 21 (47.7%) | 23 (52.3%) |
Genotype distribution compared percentages: χ 2 15.604, d.f. 4; P = .004.
Allele distributions compared percentages: χ 2 6.661, d.f. 2; P < .05.
