Nuclear factor (NF)-κB essential modifier (NEMO), also known as IκB kinase subunit-γ (IKKγ), is a pivotal molecule in the NF-κB signaling pathway. Mutations of NEMO cause incontinentia pigmenti and X-linked ectodermal dysplasia with immunodeficiency. Mendelian susceptibility to mycobacterial diseases (MSMD), which confers an almost selective predisposition to mycobacterial infection, is also caused by NEMO mutations. Read More

Incontinentia pigmenti (IP) is a rare X-linked dominant disorder that can cause retinal nonperfusion, neovascularization, and retinal detachment. Evaluation of the peripheral retinal vasculature and appropriate treatment can reduce the risk of blindness. The authors report the use of a handheld prototype optical coherence tomography angiography (OCTA) and ultra-widefield OCT (UWF-OCT) during exam under anesthesia of a 2-year-old with a history of severe early onset IP.

Incontinentia pigmenti (IP) is a rare X-linked multisystem disorder that mainly affects females and is usually lethal to males in utero. Mutations in the NEMO gene on chromosome Xq28 (IKBKG, inhibitor of kB kinase gamma) have been shown to cause IP. Approximately 35% of patients have ophthalmic manifestations, and 20% develop vision-threatening diseases. Read More

Importance: Incontinentia pigmenti (IP) is a rare, X-linked dominant disease with potentially severe ocular complications that predominantly affect the peripheral retina. However, little is known about its effects on the macula.

We describe a new mutation in exon 4 of IKBKG, encoding nuclear factor-kappa B in a patient with incontinentia pigmenti. The patient had a severe cholestatic liver disease with features of a ciliopathy and underwent liver transplantation. We cannot establish a link between incontinentia pigmenti, a very rare disease, and hepatic ciliopathy, but we suggest that hepatic evaluation should be considered in patients with incontinentia pigmenti.

Incontinentia pigmenti (IP) is a rare X-linked dominant disease that affects the ectodermal tissues. It is associated with a whorled pattern of scarring alopecia, which is possibly underreported. This scarring alopecia could be used as a marker to identify adult women affected with IP as older patients may have minimal cutaneous manifestations. Read More

Purpose Of Review: This article presents an up-to-date summary of the genetic etiology, diagnostic criteria, clinical features, and current management recommendations for the most common neurocutaneous disorders encountered in clinical adult and pediatric neurology practices.
Recent Findings: The phakomatoses are a phenotypically and genetically diverse group of multisystem disorders that primarily affect the skin and central nervous system. A greater understanding of the genetic and biological underpinnings of numerous neurocutaneous disorders has led to better clinical characterization, more refined diagnostic criteria, and improved treatments in neurofibromatosis type 1, Legius syndrome, neurofibromatosis type 2, Noonan syndrome with multiple lentigines, tuberous sclerosis complex, Sturge-Weber syndrome, and incontinentia pigmenti.

Background: Incontinentia pigmenti (IP) is a rare inherited genodermatosis that usually involves the skin, and also teeth, oral cavity, central nervous system, eyes, blood with eosinophilia, and rarely skeletal system, breast, heart, and lungs. Skin lesions usually appear early, at birth or within the first 2 weeks of life, with four different phases tending to follow Blaschko lines that may overlap.
Case Report: We report a rare case of a neonate with transient reversible pulmonary hypertension that presented at day 9 of life. Read More

Incontinentia pigmenti (IP) is a genetic disorder caused by mutations in IKBKG, leading to functional loss of nuclear factor kappa B (NF-ĸB). We report the case of a 6-month-old female child with IP who presented with unilateral nystagmus and was found to have a pilocytic astrocytoma with leptomeningeal spread. Enhanced understanding of the relationship between NF-ĸB, along with its upstream regulators, and tumorigenesis may shed light on whether a subset of patients with IP may be at increased risk for neoplasia.

The nuclear factor (NF)-κB essential modulator (NEMO) is a key regulator in NF-κB-mediated signaling. By transmitting extracellular or intracellular signals, NEMO can control NF-κB-regulated genes. NEMO dysfunction is associated with inherited diseases such as incontinentia pigmenti (IP), ectodermal dysplasia, anhidrotic, with immunodeficiency (EDA-ID), and some cancers. Read More

Incontinentia pigmenti (IP) is a rare X-linked dominant disorder, in which skin lesions distributed along Blaschko's lines appear shortly after birth. Early lesions which are erythematous/bullous evolve over time into warty lesions, hyperpigmented swirls/macules, and atrophic hypopigmented streaks. Clinical features are heterogeneous. Read More

Background: Incontinentia pigmenti is a rare X-linked dominant syndrome caused by mutation in the NEMO/IKKgamma gene, and characterized by a spectrum of cutaneous, ocular, neurologic and dental abnormalities. In the eye, findings include retinal vascular non-perfusion, occasionally with traction retinal detachment, retinal fibrosis, and retinal pigment epithelium defects. These findings can resemble retinoblastoma, especially when vitreoretinal fibrosis produces leukocoria. Read More

Incontinentia pigmenti (IP; Online Mendelian Inheritance in Man catalog #308300) is an X-linked dominant ectodermal disorder caused by mutations of the inhibitor of κ polypeptide gene enchancer in B cells, kinase γ ()/ nuclear factor κB, essential modulator () gene. Hemizygous loss-of-function (LoF) mutations are lethal in males, thus patients are female, and the disease is always transmitted from an IP-affected mother to her daughter. We present 2 families with father-to-daughter transmission of IP and provide for the first time molecular evidence that the combination of somatic and germ-line mosaicism for loss of function mutations in IP males resulted in the transmission of the disease to a female child.

Incontinentia pigmenti (IP) is an X-linked genodermatosis affecting the skin and other sites, including the teeth, nails, hair, eyes and nervous system defects in female patients. Generally lethal in males, there are only a few known cases of males surviving this condition. Nuclear factor (NF)-κB essential modulator (NEMO), also known as inhibitor of kappa light polypeptide gene enhancer in B cells, kinase gamma (IKBKG), constitutes an essential activator of NF-κB.

Incontinentia Pigmenti (IP) is a skin disorder with neurological impairment in 30% of cases. The most common disease causing mutation is a deletion of exons 4-10 of the IKBKG gene, located on chromosome Xq28, with skewed X-chromosome inactivation in females, but few cases of random X-inactivation have been reported. We have correlated brain anomalies with X-chromosome inactivation status determined on leucocytes circulating DNA. Read More

Purpose: Anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID) is caused by mutations in the NF-κB essential modulator (NEMO) or NF-κB inhibitor, alpha (IKBA) genes. A heterozygous NEMO mutation causes incontinentia pigmenti (IP) in females, while a hemizygous hypomorphic mutation of NEMO causes EDA-ID in males. In general, immunodeficiency is not shown in IP patients. Read More

Background: Incontinentia pigmenti (IP; MIM308300) is a severe, male-lethal, X-linked, dominant genodermatosis resulting from loss-of-function mutations in the IKBKG gene encoding nuclear factor κB (NF-κB) essential modulator (NEMO; the regulatory subunit of the IκB kinase [IKK] complex). In 80% of cases of IP, the deletion of exons 4 to 10 leads to the absence of NEMO and total inhibition of NF-κB signaling. Here we describe a new IKBKG mutation responsible for IP resulting in an inactive truncated form of NEMO. Read More

The NF-κB pathway has critical roles in cancer, immunity and inflammatory responses. Understanding the mechanism(s) by which mutations in genes involved in the pathway cause disease has provided valuable insight into its regulation, yet many aspects remain unexplained. Several lines of evidence have led to the hypothesis that the regulatory/sensor protein NEMO acts as a biological binary switch. Read More

Sweating is regulated by various neurohormonal mechanisms. A disorder in any part of the sweating regulatory pathways, such as the thermal center, neurotransmitters in the central to peripheral nerve, innervation of periglandular neurotransmission, and sweat secretion in the sweat gland itself, induces dyshidrosis. Therefore, hereditary disorders with dyshidrosis result from a variety of causes. Read More
