Autism may include distinct genetic subtypes, study shows autism traits follow two paths
Source: scitechdaily.com Key Points: Autism has two genetically based paths. Genetics largely shapes the diagnosis age. Subtypes can guide better care. The age at which children are diagnosed with autism appears to be shaped by genetic factors, suggesting that autism may consist of multiple, genetically distinct subtypes, or autism genetic subtypes. Researchers found that children diagnosed earlier or later in life followed different developmental paths, which were linked to variations in their DNA. Autism is a neurodevelopmental condition marked by challenges in social interaction, communication, and restricted or repetitive behaviors. According to the World Health Organization, about one in 127 people worldwide is autistic. Findings on diagnosis patterns The study, led by Varun Warrier at the University of Cambridge, analyzed data from children diagnosed with autism between the ages of 5 and 17. Caregivers completed questionnaires about social, emotional, and behavioral develop...
