What is trisomy 13?

Also known as: Patau syndrome

Trisomy 13 is a chromosome disorder that is present at birth. Patients with the condition have a third copy of chromosome 13 in their cells, which leads to a variety of lifelong symptoms ranging from intellectual disability to heart defects, spine abnormalities, cleft palate and more. Some people only have some cells with an extra chromosome 13, which is known as mosaic trisomy 13.
