Research Registry for Inherited Disorders of Keratinization

The purpose of this registry is to support studies aimed at determining the cause of the ichthyoses and treating them more effectively. The Registry offers blinded information about well-characterized groups of individuals with specific diagnoses for study by skin biologists, pharmacologists, and others. The Registry also provides information about research projects to those that have enrolled in the Registry and expressed an interest in participating in studies. 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.
