With Down Syndrome, a person's cells contain a third copy of chromosome 21 -- hence the disorder's scientific name, trisomy 21. Kanako was born in captivity in 1992 at a Japanese wildlife facility.

Triple X syndrome, also known as 47, XXX, Triple X, Triplo-X, or trisomy x is a sex chromosome aneuploidy, or chromosome abnormality, in which females have an additional X chromosome. The number ...

Down syndrome, a genetic disorder characterized by an extra copy of the 21st chromosome (trisomy 21), affects around one in every 1,000 individuals and raises the chance of developing pediatric ...

This paper reports a rare case of complicated karyotype :45,X/47,XY,+18,−19,+der (19),t (Y;19) (q12;p13.3). The culture of skin fibroblasts, however, showed only 45,X cells. The patient, 14-year ...
