High frequency of primary hereditary ichthyoses in the North-East region of Cairo, Egypt.

Introduction: Inherited ichthyoses are caused by mutations in various genes important for keratinocyte differentiation and epidermal barrier function. Although ichthyoses are rare disorders, they require costly long-term medical management, and thus there is a need for efficient preventive and therapeutic strategies.

Aim: We performed a retrospective study to determine the frequency, types, clinical presentation and associated genomic errors of primary hereditary ichthyoses in Egyptian patients and their relatives consulting the Genetics Clinic, Pediatric Hospital, Ain Shams University.
