Summary

Story summary

Researchers identify a genetic basis across eight psychiatric conditions, autism and ADHD.
They identify brain-development variants influencing multiple disorders.
About 70% of individuals with autism or ADHD have the other condition.
The study examined nearly 18,000 gene variations, revealing 683 regulatory variants in neurons.
The study, published in Cell, finds pleiotropic variants interact broadly across brain cells.
