Only eight markers were found to be polymorphic. rs6323 "G" allele showed higher frequencies in ADHD (P = 0.0023), ADHD + CD (P = 0.03) and ADHD + ODD (P = 0.01) as compared to controls.
In interaction analysis, the FOXP2-TCGC (rs12531289-rs1350135-rs10230087-rs2061183) diplotype and MAOA-TCG (rs6323-rs1801291-rs3027407) haplotype were significantly associated with autism spectrum disorder in males.

We identified a c.797_798delinsTT (p.C266F) missense mutation in MAOA in a boy with autism spectrum disorder, attention deficit and autoaggressive behavior.

These findings suggest that the low activity-related C allele of MAOA rs1137070 is associated with an increase in the sensitivity to heroin addiction and the damaging effects of heroin abuse on cognition and the salience network.
Heroin addiction and the rs1137070 variant interactively altered measures of GMV in the anterior cingulate cortex, orbital frontal cortex, temporal pole, and insula, which were correlated with cognitive function.
We also found that MAOA enzyme activity by rs1137070 allele was associated with hyperuricemia and gout (P for trend = 1.53 x 10(-6) vs. wild-type allele).
Quantitative real-time polymerase chain reaction analysis showed that overall relative quantity of MAOA messenger RNA was significantly higher in patients with MDD than in control subjects (fold change = 5.28, p = 1.7 × 10⁻⁷) and that in the male subjects carrying the VNTR-L, rs1465107-A, rs6323-G, rs2072743-A, or rs1137070-T alleles, expression of MAOA messenger RNA was significantly higher in the patient group than in the control group.
We identified a synonymous SNP rs1137070 showing significant associations with major depressive disorder (p = 0.00067, OR = 1.263 for T allele) and schizophrenia (p = 0.0039, OR = 1.225 for T allele) as well as a broad spectrum of psychiatric phenotype (p = 0.000066, OR = 1.218 for T allele) in both males and females.
Among the females, an association was found between MAOA polymorphisms and severe MDD (P=0.041 for uVNTR and 0.017 for EcoRV (rs1137070), respectively).
