Down syndrome, also known as trisomy 21, is the most frequent form of cognitive disability caused by a microscopically demonstrable chromosomal aberration. It is caused by a third copy (trisomy) of all or a critical portion of chromosome 21. Down syndrome is characterized by physical growth delays, dysmorphic facial features, heart and gastrointestinal disorders, and mild to moderate cognitive disability. [provided by RefSeq, Jul 2017]
