Ichthyosis prematurity syndrome (IPS) is a rare form of autosomal recessive congenital ichthyosis caused by mutations in SLC27A4 (OMIM: 604194) encoding fatty acid transport protein 4 (FATP4) that affect keratinocyte differentiation and skin barrier formation. It is characterized by prematurity, thick caseous desquamating epidermis, and perinatal respiratory asphyxia. Despite its well-described clinical features and major perinatal mortality risk, IPS is still rarely recognized, and only a few cases have been reported.
