trisomía 21

trisomía 21

A genetically inherited form of mental retardation usually resulting from the inheritance of an extra autosome 21. Down syndrome individuals also typically are short and stocky in build with short appendages. They usually have broad round faces, saddle-shaped nose profiles, and thick tongues that are often stuck out of their mouths. The incidence of Down syndrome children goes up rapidly with the age of the mother, particularly after 40.
