UNDERSTANDING SMS
What is Smith-Magenis Syndrome?
Smith-Magenis syndrome (SMS) is a rare neurobehavioral disorder characterized by a recognizable pattern of physical, behavioral, and developmental features. SMS is caused by a deletion or mutation of genetic material on chromosomal region 17p11.2, which contains the RAI1 gene.
What is the Incidence of Smith-Magenis Syndrome?
SMS occurs in between 1 out of every 15,000 to 25,000 births. Although the number of individuals diagnosed with SMS has increased in recent years due to better diagnostic tools, the syndrome likely remains under diagnosed. PRISMS has a Patient Registry that allows us to continue learning about this rare condition, helping researchers, clinicians, and parents better address the challenges of SMS.
How is Smith-Magenis Syndrome Diagnosed?
The diagnosis of Smith-Magenis syndrome is usually confirmed through a clinical blood test called a chromosome analysis. Diagnosis can also be made through a chromosome microarray analysis (CGH), a cytogenetic test, or FISH (fluorescence in situ hybridization). Once a diagnosis is confirmed, caregivers and physicians can use the Medical Management Guidelines to guide care. PRISMS currently has nine SMS Clinics around the country that provide specialized care for those with SMS.
WORK THAT CHANGES LIVES
What Treatment is Available?
There are no medications that can cure Smith-Magenis syndrome or eliminate the core symptoms. However, there are medications that can help people with Smith-Magenis syndrome lead healthier lives. For example, medication might help manage behavioral challenges, sleep difficulties, gastrointestinal issues, inability to focus, or seizures.
