There are several effective ways to diagnose the syndrome. First of all, the guesses of any parent are based on the unusual appearance and learning abilities. It is not that easy to tell that something’s wrong with the heart or kidneys. If you take the child to the corresponding health care provider, he will most probably conduct a fluorescent in situ hybridization (FISH) to approve or disapprove your guesses.

The aim is to analyze DNA consistency as the disorder is passed on the genetic level. If the particular gene is absent, the diagnosis is confirmed. The doctors also recommend doing a kidney ultrasound and examine blood pressure.
