IPEX (immune dysregulation, polyendocrinopathy, enteropathy, X-linked) is an X-linked recessive syndrome involving aggressive autoimmunity.

Diagnosis of IPEX syndrome is suggested by clinical features and confirmed by genetic analysis. Genetic counseling and targeted genetic testing for siblings and offspring should be considered.
