6. Traits whose genes increase ADHD risk


6. Traits whose genes increase ADHD risk

A large-scale genetic study found several complex traits whose genetic causes put people at higher risk for ADHD:1

GCP : Genetical causal proportion.
Negative values mean that the trait is a causal risk for ADHD (the lower the negative value, the stronger). Positive values mean that the trait is a causal consequence of ADHD (the higher the positive value, the stronger).
