Overview

X-linked Ichthyosis is a hereditary skin condition characterized by dry, thick, and scaly skin. It is caused by a deficiency of the enzyme steroid sulfatase, which affects normal skin shedding.

This condition primarily affects males and usually becomes noticeable in infancy or early childhood. While it is not life-threatening, it requires long-term skin care and management.
