WebApr 15, 2024 · Aneuploidy (AN-yuh-ploy-dee) happens when a baby has too few or too many chromosomes. This can cause a chromosome disorder like Down syndrome. Aneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. It does not include a difference of one or more complete sets of chromosomes. A cell with any number of complete chromosome sets is called a euploid cell. An extra or missing chromosome is a common cause of some genetic disorders. …
