Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Although the Registry is closed to new enrollment, it is still maintained in order to provide information related to understanding the diagnosis, pathophysiology, and treatment of ichthyoses. Support for studies continues and inquiries from investigators are welcomed.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participants enrolled in the Registry by contacting the registry officials. All participants participated in a phone interview with the study research nurse. Participants were asked about diagnostic testing, treatments, birth history, medical history, degree and type of involvement, current physical condition, and other family members with skin disorders. A quality of life index was embedded in the interview. Participants also indicated whether they would like to be contacted about participating in clinical research. This information was complemented by an enrollment form from the enrollee's caregiver.
Diagnosis was confirmed by specific criteria based on clinical involvement, review of histology, and where appropriate, serum cholesterol sulfate determination or DNA analysis.
