Ancient DNA Reveals Trisomy 13 in 1,600-Year-Old Peruvian Infant

Archaeologists in southern Peru have discovered the remains of two infants buried together in a single ceramic vessel. Genetic analysis revealed that one of the infants exhibited cyclopia caused by trisomy 13, a rare chromosomal condition. Researchers noted that this physical condition did not result in unusual treatment during the infant's life or death. The discovery provides valuable insights into both ancient funerary practices and the historical presence of congenital differences in human populations.
