Key Fact
Genetic testing is used to confirm a diagnosis of Smith-Magenis syndrome.

Diagnosis of Smith-Magenis Syndrome


Diagnosis of Smith-Magenis syndrome is confirmed through genetic testing after initial clinical findings (i.e. physical characteristics).

 

Cytogenetic testing (analysis of the number and structure of chromosomes) is used to detect the deletion and molecular genetic testing is used to determine whether there is a deletion on chromosome 17p11.2 including RAI1 or a mutation of the RAI1 gene.
