Down syndrome

Down syndrome encompasses a number of genetic disorders, of which trisomy 21 (a nondisjunction) is the most representative, causing highly variable degrees of learning difficulties as well as physical disabilities. It is named for John Langdon-Down, the British doctor who first described it in the late 19th century.
