Overview


Incontinentia pigmenti (IP) is a genetic condition affecting the skin and other body systems. Skin symptoms change with time, beginning with a blistering rash in infancy, followed by wart-like skin growths, which then become swirled grey or brown patches in childhood, to swirled light patches in adulthood. Other signs and symptoms may include hair loss, small or missing teeth, eye abnormalities that can lead to vision loss, and lined or pitted fingernails and toenails. Most people with incontinentia pigmenti have normal intelligence, however some have delayed development, intellectual disability, seizures, or other neurological problems. IP is caused by mutations in the IKBKG gene. It is inherited in an X-linked dominant fashion.[1]
