X-linked ichthyosis (abbreviated XLI) is a skin condition caused by the hereditary deficiency of the steroid sulfatase (STS) enzyme that affects 1 in 2000 to 1 in 6000 males.[2] XLI manifests with dry, scaly skin[3] and is due to deletions[4][5] or mutations[6] in the STS gene. XLI can also occur in the context of larger deletions causing contiguous gene syndromes.[4] Treatment is largely aimed at alleviating the skin symptoms.[7] The term is from the Ancient Greek 'ichthys' meaning 'fish'.
