The set of physical, mental, and functional abnormalities that result from trisomy 21, the presence in the genome of three (rather than the normal two) chromosomes 21. Down syndrome is one of the most frequent genetic causes of intellectual disability (formerly known as mental retardation). The genetic aberration that causes Down syndrome is trisomy 21, in which an individual has a full or partial extra copy of chromosome 21 |
