Patau Syndrome is a trisomy of chromosome 13 due to a nondisjunction during meiosis. Patau Syndrome can also result from a Robertsonian translocation, a section of chromosome 13 attaches to another chromosome. This results in cell containing 2 intact copies of chromosome 13 and an extra partial copy. Patau Syndrome has a prevalence of around 1 in every 10,000 live births[1] .
Signs and Symptoms of Trisomy 13
Infants ususally have a normal birth weight, a tiny head and a titlted forehead. [2]
