Very rare...: Harlequin ichthyosis is a severe genetic disorder that mainly affects the skin. Infants with this condition are born with very hard, thick skin covering most of their bodies. Harlequin ichthyosis is very rare; its exact incidence is unknown. Mutations in the abca12 gene cause this disease. The abca12 gene provides instructions for making a protein that is essential for normal skin development.
