A study published in Nature Medicine in 2026 analyzed the genetic data of more than 15,000 people from America, including people with autism and their families. The research focused on identifying genetic variations associated with autism. The analysis defined the genetic landscape of autism in Latin American populations. It was found that there is a significant overlap of deleterious genetic variation associated with autism between different ancestries. These findings contribute to a better understanding of the genetic basis of autism in different ethnic groups. The study confirms that the genetic risks of autism are not limited to one ethnic group.
