Doubling of Y Chromosome Linked to Increased Autism Risk in Males

Oct 18, 2024, 10:19 AM

Researchers have discovered a significant link between the Y chromosome and an increased risk of autism, particularly in males. A study conducted by Geisinger Health and published in Nature Communications found that individuals with an additional Y chromosome are twice as likely to be diagnosed with autism. This finding may explain the higher prevalence of Autism Spectrum Disorder (ASD) in males. The doubling of the Y chromosome doubles the risk of autism.
