Considering mothers carrying the ADH1B*2/*2 genotype, children whose mothers consumed alcohol during pregnancy had an increased risk of developmental delay in communication skills when compared with those whose mothers did not drink alcohol (cOR, 7.27; 95% CI, 2.22–23.80; aOR, 7.05; 95% CI, 2.10–23.70). Here, ADH1B is linked to Global developmental delay.
