What are the long-term health effects for a child with patau syndrome?

Confusing question. This syndrome results when an egg with a pair of chromosome 13 (instead of 1) joins with the male's 13 at conception leading to a trisomy 13.This distorts the information in each cell of the body so many complex organs do not form properly (heart,brain defects,etc.).It cannot be fixed.These kids do not live very long.
