How Is "Simpson-Golabi-Behmel Syndrome" Diagnosed?

The diagnosis is made clinically by an expert with experience in syndromes. The detection of a mutation in GPC3 or GPC4 confirms the diagnosis.

What Is the Risk of Cancer?

It is estimated that 8% of children develop a kidney tumor (Wilms’ tumor). However, this is a rough estimate. For the other tumors, the risk is even less known.

What Is Known About the Development of "Simpson-Golabi-Behmel Syndrome"?

Simpsom-Golabi-Behmel syndrome is caused by a mutation, i.e., a genetic change in the GPC3 or GPC4 gene. Both genes are located on the X chromosome. These genes control important biological processes crucial during mental and physical development. There are patients with SGBS in whom no mutations are found. In this case, an as-yet-unknown disease gene may be affected.

Is There Any Form of Treatment Available?

Caring for children requires an expert multi-professional team that works closely with the family concerned.
