X-Linked Ichthyosis is a genetic skin disorder caused by a mutation in the STSL gene, which is located on the X chromosome. This condition primarily affects males, as they have only one X chromosome. Individuals with X-Linked Ichthyosis experience dry, scaly skin, particularly on the arms, legs, and torso, due to a deficiency in an enzyme that helps maintain skin moisture. The severity of symptoms can vary, but the condition is usually diagnosed in early childhood. While there is no cure, treatments such as moisturizers and topical therapies can help manage the skin's appearance and improve comfort. Regular dermatological care is recommended for those affected.
