Summary

Story summary

Pennsylvania State University researchers show autism and developmental delays involve multiple genetic changes.
They outline a 'multi-hit' model where secondary variants modify primary variants.
In 442 individuals with a specific chromosome deletion, outcomes vary by variant type.
Findings support personalized treatment considering both primary and secondary variants; National Institutes of Health (NIH) funded the work.
