7. Characteristics whose genes increase the risk of ADHD
A large-scale genetic study found several complex traits, the genetic causes of which mean a higher risk of 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).
