What is Phelan-McDermid Syndrome?

Phelan-McDermid syndrome (PMS) is a rare genetic condition that causes developmental and speech delays, behavioral problems and a weakened or no ability to feel pain or sweat. Phelan-McDermid syndrome is a congenital condition (condition that is present at birth) that can affect people of all genders.

What Causes PMS?

PMS is caused by a mutation (change) or deletion of theSHANK3 gene (piece of genetic material). In most cases, PMS happens at random. It is not anyone’s fault.

How Can a Person Develop PMS?

There are 4 different ways that a person can develop PMS:

• Simple deletion. This is the most common type of PMS. It is when a piece of chromosome 22(piece of genetic material) on the SHANK3 gene gets lost. This usually happens at random.

• Ring chromosome. This is when chromosome 22 on the SHANK3 gene forms a circle instead of the typical X-shape.

• Unbalanced translocation. This can happen when parents do not know that one or both parents carry the chromosome for PMS.
• Mutation in the DNA sequence (order) of the SHANK3 gene. This usually happens at random.

What Are the Signs of PMS?

Most children with PMS show signs in early childhood. Other children show signs as early as their first 6 months of life. Signs can be different in every person with PMS.

PMS signs can affect development, behavior and physical appearance.
