Full trisomy 9 is a rare and fatal chromosomal disorder caused by having three copies of chromosome number 9.It can be a viable condition if the trisomic component affects only part of the cells of the body or in cases of partial trisomy of the short arm (trisomy 9p) in which cells have a normal set of two entire chromosomes 9 plus part of a third copy of the short arm ("p") of the chromosome.
Trisomy 9; Trisomy 8 (Warkany syndrome 2) Of these, Trisomy 21 and Trisomy 18 are the most common. In rare cases, a fetus with Trisomy 13 can survive, giving rise to Patau syndrome.

Trisomy 18 (Edwards syndrome) affects 1 in 6,000 births, and trisomy 13 (Patau syndrome) affects 1 in 10,000 births. 10% of infants with trisomy 18 or 13 reach 1 year of age. [ 9 ] Changes in chromosome number may not necessarily be present in all cells in an individual.
