What is the cause of PAtau syndrome?

Patau syndrome is the result of unique distribution of chromosomal pair of three in place of two.

Explanation:

A chromosomal disorder resulting in physical and intellectual disabilities of a child is widely known as Trisomy 13 or Patau syndrome. The symptoms include - defect in heart, abnor-mality in brain and spine, poor development of eyes, unusual number of fingers, a cleft lip or cleft palate and hypotonic or weakness in muscle.

The extra pair of chromosome, the pair of three, either in every cell or in few cells of the body is the main cause of this disease. However, it can also occur if the chromosomes are translocated.
