ADHD up to 15x more likely with 3 gene variants

Study identifies 3 gene variants increasing ADHD risk by up to 15x.

Why it matters

  • First identification of specific high-risk genes for ADHD.
  • Provides biological insight into ADHD's genetic basis.

By the numbers

  • Study analyzed 9,000 with ADHD, 54,000 without.
  • 15x increased risk with three gene variants.
  • Genes involved: MAP1A, ANO8, ANK2.

The big picture

  • Findings suggest brain development disturbances central to ADHD.
  • Protein network implicated in other neurodevelopmental disorders.
  • Potential for improved diagnostics and treatments.

What they're saying

  • Hope for more research on treatments, not just diagnosis.
  • Concerns about treatment impacts on personality.

Caveats

  • Study focused on Danish population.
  • More gene variants yet to be discovered.

What’s next

  • Larger studies to identify more rare causal variants.
  • Research into new therapeutic targets.
