X-linked ichthyosis (XLI) is characterized by abnormal desquamation, presenting with dry and scaly skin. It is caused by a deficiency of the steroid sulfatase enzyme, encoded by the steroid sulfatase (STS) (Xp22.3) gene. Steroid sulfatase cleaves sulfate groups from multiple steroid hormones, affecting their bioavailability. With an incidence of 1 in 2500 to 1 in 6000 males, XLI is the second most common type of ichthyosis, following ichthyosis vulgaris. These patients may have extracutaneous comorbidities, including cryptorchidism, corneal opacities, Dupuytren’s contracture, cardiac arrhythmias, bleeding disorders, and neurodevelopmental and psychiatric conditions. This case report describes an adolescent with an STS deletion identified after a sudden cardiac arrest.
