In brief: Not inherited
Patau syndrome, or trisomy 13, is not inherited, in that a baby does not "get it" from either parent.
It is usually caused when the egg does not divide properly at the time of fertilization. This accident causes a baby to get an extra number 13 chromosome in every one of its cells. Trisomy 13 is rare, but a very serious condition. Most babies with it die before birth or shortly after birth.
