First common risk genes discovered for autism

genes discovered for autism-1

Researchers from the iPSYCH project and the Broad Institute have made a groundbreaking discovery by identifying the first common risk genes for autism. These genes increase the risk of developing autism and provide insights that could lead to better treatment options in the future. The study, published in Nature Genetics, analyzed the genomes of 20,415 individuals with autism and 174,280 healthy control subjects. By comparing these genomes, the researchers were able to identify five genetic variants that contribute to the risk of autism.

Autism is a complex disorder with a strong genetic component. Previous research has shown that up to 80% of autism cases have a hereditary factor. However, until now, common genetic risk variants for autism had not been identified. This study represents a significant step forward in our understanding of the genetic basis of autism.

The genetic risk variants for autism identified in this study play a crucial role in brain development, particularly in the cerebral cortex. Interestingly, there is also a significant overlap between the genetic background for autism and other mental disorders, such as schizophrenia and depression. Moreover, the study found a positive correlation between genes associated with autism and educational attainment and IQ. This suggests that there may be a genetic link between autism and certain cognitive abilities.

One of the important findings of the study is that different diagnostic subgroups of autism have genetic differences. This could allow for more precise diagnosis and tailored advice for individuals with autism. Additionally, the genetic variations discovered in this study have the potential to pave the way for the development of targeted treatments or preventive measures for autism spectrum disorder.

Overall, this study represents a major breakthrough in autism research. The identification of common genetic risk variants for autism provides valuable insights into the underlying genetics of the disorder and opens up new possibilities for improving diagnosis and treatment in the future.
