Also it only contains "recognisable patterns" so not all of the rarer trisomies are included as they don't have an identified "pattern" (as yet, usually due to small a number of reported cases). What it does have is T-21, T-18, T-13, T-8, T-9 mosaic, Triploid, Diploid/ Triploid, and mixploidy syndromes, 3q duplication, 4p duplication, 9p duplication, 10q duplication, 15q duplication, cat eye syndrome (interstitial duplication of 22q11)XXY, XYY, XXXY, XXXXY, XXX, XXXX, and XXXXX. Thats about it for duplications. Lots of deletions and a zillion other conditions as well (eg Russell-Silver syndrome, Miller Syndrome, Larsen syndrome) - the book is 800 pages long. **************Ideas to please picky eaters.
