They also found that the EcoRV allele with the EcoRV site present and MAOA uVNTR’s 3R allele significantly correlated with depression in males better than any of the polymorphic alleles alone (p = 0.008; OR = 2.5, OR CI = 1.3–4.8) and with higher insomnia scores compared to other haplotype carriers (HAM-D clusters compared by unpaired Student t-test, t = 2.7, p = 0.008), even after correction for multiple testing (p = 0.048 in both cases) [23]. Here, MAOA is linked to insomnia measurement.
