"Uncovering Ancient Down Syndrome Cases Through Genetic Signatures"

Scientists have identified the genetic signature of Down syndrome in ancient bones of seven infants, some dating back 5,500 years, shedding light on how prehistoric societies may have treated individuals with rare conditions. The method, published in Nature Communications, may provide insight into the historical prevalence and treatment of Down syndrome, which is caused by an extra copy of chromosome 21 and can result in various health challenges. This discovery challenges the difficulty of confidently diagnosing ancient skeletons with Down syndrome due to its variable nature.
