Those children who do survive past 1 year of life are typically severely disabled with intellectual disability, seizures, and psychomotor issues. Children with the mosaic variation are usually affected to a lesser extent. [9] In a retrospective Canadian study of 174 children with trisomy 13, median survival time was 12.5 days.
Trisomy 13 (Patau syndrome), trisomy 18 (Edwards syndrome) Triploid syndrome , also called triploidy , is a chromosomal disorder in which a fetus has three copies of every chromosome instead of the normal two.

Trisomy 13 can also result from an extra copy of chromosome 13 in only some of the body's cells (mosaic trisomy 13).

Although many children with holoprosencephaly have normal chromosomes, specific chromosomal abnormalities have been identified in some patients (trisomy of chromosome 13, also known as Patau syndrome).
