A 40-bp VNTR polymorphism in the 3′-untranslated region of DAT1/SLC6A3 is associated with ADHD but not with alcoholism

Table 1 Genotype distribution of 40-bp VNTR polymorphism in ADHD and controls

Genotype	9/9	9/10	10/10	Atypical/rare genotypes	Total	p
ADHD	6	81	125	6	218	0,0079
controls	17	101	135	0	253

The statistical difference between genotype frequencies was calculated using Fisher’s exact test
