While Down syndrome is listed in many dictionaries with both popular spellings (with or without an apostrophe s), the preferred usage in the United States is Down syndrome. Adjustments are made to take account of this. Down syndrome (also called trisomy 21 or trisomy of chromosome 21), is the most common chromosome abnormality in newborns. 0000015986 00000 n Down syndrome mosaicism presumably results from nondisjunction (when chromosomes fail to pass to separate cells) during cell division in the embryo. 0000021446 00000 n A person who has Down syndrome is born with an extra copy of the 21st chromosome.
