Can gene mutations lead to different ADHD presentations?

ByMy Patient Advice

Yes, specific gene mutations may play a role in how ADHD presents differently across individuals. While most cases of ADHD stem from a combination of genetic and environmental factors, rare or impactful gene mutations in ADHD can influence how the condition presents, whether predominantly inattentive, hyperactive-impulsive, or combined. These mutations can affect brain development, neurotransmitter regulation, or cognitive processing, all of which help shape specific symptom patterns. 

This explains why two people with ADHD may have vastly different experiences and support needs.

Genetics and ADHD diversity 

Here’s how gene differences relate to variations in ADHD. 

ADHD subtypes 

Mutations in genes linked to dopamine, serotonin, or norepinephrine can lead to differences in focus, energy, and impulse control, aligning with distinct ADHD subtypes. For example, dopamine-related mutations are more commonly seen in individuals with hyperactive traits. 

Genetic presentation 

Genetic presentation refers to how a person’s unique genetic makeup influences their ADHD symptoms. A child with a rare mutation affecting executive function may struggle more with planning and organisation, while another with a different mutation might show mood-related challenges. 

By studying gene mutations in ADHD, clinicians can develop more individualised interventions. Visit providers like ADHD Certify to explore advanced assessments and personalised care strategies based on genetic insights.
