In brief: Trisomy 13

Patau syndrome is also called trisomy 13.
It occurs when a baby has 3 copies of the number 13 chromosome instead of the usual 2 copies. It causes severe physical problems and most babies with trisomy 13 die before birth or within the first year after birth. It usually happens because of an accident which occurs when the egg is fertilized, and occurs more commonly as mothers get older.
