Scientific Definition

Phelan-McDermid Syndrome (PMS) is a rare genetic disorder. It’s caused by a loss or change in the SHANK3 gene located at the end of chromosome 22. This gene plays a critical role in brain development. PMS often leads to intellectual disabilities, delayed or absent speech, and autism-like behaviors. Additionally, it can cause physical characteristics such as low muscle tone and minor facial differences. Although PMS presents challenges, with the right support, individuals with PMS can lead enriched and fulfilling lives.
