When someone has three copies of chromosome 13 in all of their cells, they have complete trisomy 13. Around 95% of children with a diagnosis of trisomy 13 are thought to have complete trisomy 13. The other 5% have mosaic trisomy 13. This means that some of their cells have the normal 2 copies of chromosome 13, and other cells have 3 copies of chromosome 13.
