What Causes Patau Syndrome?

Causes.

Patau syndrome is the result of trisomy 13, meaning each cell in the body has three copies of chromosome 13 instead of the usual two.

A small percentage of cases occur when only some of the body’s cells have an extra copy; such cases are called mosaic Patau.

What are the causes of Trisomy 13?

Most cases of trisomy 13 are caused by random events during the formation of eggs or sperm in healthy parents (prior to conception). Trisomy 13 is typically due to having three full copies of chromosome 13 in each cell in the body, instead of the usual two copies.

What is the life expectancy of a person with Patau syndrome?

The median life expectancy of Patau syndrome is 7–10 days, and 90% die in the first year of life. Survival is often attributed to mosaicism and the severity of associated malformations.

How is Patau syndrome diagnosed?

Due to the presence of several life-threatening medical problems, many infants with trisomy 13 die within their first days or weeks of life.

Do babies with Trisomy 13 suffer?
