Research: very early developmental changes caused by Trisomy 21 are identified

Scientists have revealed the earliest developmental changes that lead to Down's syndrome.

The team from Barts and the Royal London (Hospitals) say the changes to embryonic stem cells are caused by the presence of an extra copy of chromosome 21.

The study, in the American Journal of Human Genetics, says the extra chromosome sets off a chain of genetic changes in the developing embryo.
