NINDS:42 Incontinentia pigmenti (IP) is an inherited disorder of skin pigmentation that is also associated with abnormalities of the teeth, skeletal system, eyes, and central nervous system. It is one of a group of gene-linked diseases known as neurocutaneous disorders. In most cases, IP is caused by mutations in a gene called NEMO (NF-kappaB essential modulator). Males are more severely affected than females. Discolored skin is caused by excessive deposits of melanin (normal skin pigment). Most newborns with IP will develop discolored skin within the first two weeks. The pigmentation involves the trunk and extremities, is slate-grey, blue or brown, and is distributed in irregular marbled or wavy lines. The discoloration fades with age. Neurological problems include loss of brain tissue (known as cerebral atrophy), the formation of small cavities in the central white matter of the brain, and the loss of neurons in the cerebellar cortex. About 20% of children with IP will have slow motor development, muscle weakness in one or both sides of the body, mental retardation, and seizures. They are also likely to have visual problems, including crossed eyes, cataracts, and severe visual loss. Dental problems are also common, including missing or peg-shaped teeth. A related disorder, incontinentia pigmenti achromians, features skin patterns of light, unpigmented swirls and streaks that are the reverse of IP. Associated neurological problems are similar.
MalaCards based summary: Incontinentia Pigmenti, Type Ii, also known as incontinentia pigmenti, is related to incontinentia pigmenti achromians and ectodermal dysplasia, and has symptoms including skin rash, hypopigmented skin patches and abnormality of the fingernails. An important gene associated with Incontinentia Pigmenti, Type Ii is IKBKG (inhibitor of kappa light polypeptide gene enhancer in B-cells, kinase gamma). Affiliated tissues include skin, eye and brain.
NIH Rare Diseases:41 Incontinentia pigmenti (ip) is a genetic condition that affects the skin and other body systems. skin symptoms change with time and begin with a blistering rash in infancy, followed by wart-like skin growths. the growths become swirled grey or brown patches in childhood, and then 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 nails. most people with ip have normal intelligence, but some have developmental delay, intellectual disability, seizures, and/or other neurological problems. ip is caused by mutations in the ikbkg gene and is inherited in an x-linked dominant manner. last updated: 7/29/2014
Genetics Home Reference:21 Incontinentia pigmenti is a condition that can affect many body systems, particularly the skin. This condition occurs much more often in females than in males.
