Autism, a neurodevelopmental disorder, affects communication, behavior, and social interaction. According to the Centers for Disease Control and Prevention (CDC), one in 59 children in the United States is on the autism spectrum.

While the exact cause of autism is still uncertain, a recent study has identified 18 new genes linked to the disorder.

Study Overview

The study, which was conducted by the Autism Sequencing Consortium, was the largest genetic study of autism to date with over 35,000 participants.

The researchers analyzed the genes of individuals with autism and compared them with the genes of individuals without the disorder.

New Genes Linked to Autism

The researchers found that 102 genes were linked to autism, 18 of which had not been previously identified.

The study found that many of these genes are involved in the development and function of the brain’s synapses, the junctions that allow neurons to communicate with each other.

Implications of the Study

The study sheds light on the biology of autism and provides new potential targets for future treatments.

Many of the genes identified in the study are involved in the development and function of synapses, suggesting that disruptions in synapse function may play a role in autism.

Challenges Ahead

While the study has provided new insights into the genetics of autism, much work remains to be done.

The researchers note that the genes identified in the study only account for a small percentage of the risk for autism and that there are likely many other genes involved. Furthermore, environmental factors may also play a role in the disorder.

Conclusion

The discovery of 18 new genes linked to autism is an important step forward in understanding the disorder.

While there is much work to be done, the study provides new potential targets for future treatments and a deeper understanding of the biology of autism.
