Answer:
Patau's syndrome
Explanation:
Patau's syndrome is a genetic disorder caused by one additional chromosome 13, and therefore it is an aneuploidy caused by an extra chromosome (i.e., a trisomy). Individuals with Patau's syndrome have 47 chromosomes instead of 46 in some or all their somatic cells. This syndrome seriously affects fetal development, usually resulting in miscarriage, stillbirth or in neonatal death. The incidence of this syndrome is around 1/5,000 births.
