In brief: Chromosome error
Humans have 23 pairs of chromosomes(c) making up our dna.
When the egg or sperm form, the (c) pairs are supposed to split up with 1 (c) of each pair going to the egg or sperm.If the 13 (c) does not split & both go into an egg, fertilization will add a 3rd from dad & a trisomy 13 will begin to form. The imbalanced (c) causes malformations, miscarriage or early death.

In brief: Lethal DNA anomaly.
An extra chromosome 13 confers lethality to affected individuals, as well as cleft lip/palate, holoprosencephaly, cardiac anomalies and omphalocele (all midline defects).
