"Uncovering Ancient Cases of Down Syndrome Through DNA Analysis"

Researchers have identified cases of trisomy 21 (Down syndrome) and trisomy 18 (Edwards syndrome) in ancient and prehistoric individuals through genetic analysis of 9,855 human genomes. The study reveals six cases of Down syndrome and one case of Edwards syndrome, with evidence of skeletal abnormalities consistent with these genetic disorders. The findings suggest that these individuals were cared for and buried with respect, indicating compassionate community attitudes towards those with genetic disorders in the past. The study highlights the potential of integrating genetic, anthropological, and archaeological data to gain insights into the prevalence and societal perceptions of genetic disorders in ancient populations.
