Hypohidrotic ectodermal dysplasia with immune deficiency

Hypohidrotic ectodermal dysplasia (HED; 305100), a congenital disorder of teeth, hair, and eccrine sweat glands, is usually inherited as an X-linked recessive trait, although rarer autosomal dominant (129490) and autosomal recessive (224900) forms exist. [from OMIM]

Familial atypical mycobacteriosis, type 1, X-linked

IMD33 results from X-linked recessive NEMO deficiency, which is associated with various other diseases, including immunodeficiency with hypohidrotic ectodermal dysplasia (300291), together with osteopetrosis and lymphedema (300301) in some patients, and immunodeficiency without ectodermal dysplasia (300584). In contrast with patients with these other forms of X-linked recessive NEMO deficiency, who display a broad susceptibility to infections, infections in IMD33 patients are mostly limited to mycobacterial disease, with M. avium complex being the most common cause. Furthermore, IMD33 patients lack developmental features suggestive of hypohidrotic ectodermal dysplasia. Monocytes from IMD33 patients have intrinsic defects in T cell-dependent IL12 (see 161561) production, resulting in impaired IFNG (147570) production. The prognosis of IMD33 patients is variable (review by Al-Muhsen and Casanova, 2008). [from OMIM]

Ectodermal dysplasia, anhidrotic, with immunodeficiency, osteopetrosis, and lymphedema

Osteopetrosis is a bone disease that makes bones abnormally dense and prone to breakage (fracture). Researchers have described several major types of osteopetrosis, which are usually distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked. The different types of the disorder can also be distinguished by the severity of their signs and symptoms.Autosomal dominant osteopetrosis (ADO), which is also called Albers-Schönberg disease, is typically the mildest type of the disorder. Some affected individuals have no symptoms. In these people, the unusually dense bones may be discovered by accident when an x-ray is done for another reason. In affected individuals who develop signs and symptoms, the major features of the condition include multiple bone fractures, abnormal side-to-side curvature of the spine (scoliosis) or other spinal abnormalities, arthritis in the hips, and a bone infection called osteomyelitis. These problems usually become apparent in late childhood or adolescence.Autosomal recessive osteopetrosis (ARO) is a more severe form of the disorder that becomes apparent in early infancy. Affected individuals have a high risk of bone fracture resulting from seemingly minor bumps and falls. Their abnormally dense skull bones pinch nerves in the head and face (cranial nerves), often resulting in vision loss, hearing loss, and paralysis of facial muscles. Dense bones can also impair the function of bone marrow, preventing it from producing new blood cells and immune system cells. As a result, people with severe osteopetrosis are at risk of abnormal bleeding, a shortage of red blood cells (anemia), and recurrent infections. In the most severe cases, these bone marrow abnormalities can be life-threatening in infancy or early childhood.Other features of autosomal recessive osteopetrosis can include slow growth and short stature, dental abnormalities, and an enlarged liver and spleen (hepatosplenomegaly). Depending on the genetic changes involved, people with severe osteopetrosis can also have brain abnormalities, intellectual disability, or recurrent seizures (epilepsy).A few individuals have been diagnosed with intermediate autosomal osteopetrosis (IAO), a form of the disorder that can have either an autosomal dominant or an autosomal recessive pattern of inheritance. The signs and symptoms of this condition become noticeable in childhood and include an increased risk of bone fracture and anemia. People with this form of the disorder typically do not have life-threatening bone marrow abnormalities. However, some affected individuals have had abnormal calcium deposits (calcifications) in the brain, intellectual disability, and a form of kidney disease called renal tubular acidosis.Rarely, osteopetrosis can have an X-linked pattern of inheritance. In addition to abnormally dense bones, the X-linked form of the disorder is characterized by abnormal swelling caused by a buildup of fluid (lymphedema) and a condition called anhydrotic ectodermal dysplasia that affects the skin, hair, teeth, and sweat glands. Affected individuals also have a malfunctioning immune system (immunodeficiency), which allows severe, recurrent infections to develop. Researchers often refer to this condition as OL-EDA-ID, an acronym derived from each of the major features of the disorder.

Incontinentia pigmenti syndrome

Incontinentia pigmenti (IP) is a disorder that affects the skin, hair, teeth, nails, eyes, and central nervous system. Characteristic skin lesions evolve through four stages: I. Blistering (birth to age ~4 months). II. Wart-like rash (for several months). III. Swirling macular hyperpigmentation (age ~6 months into adulthood) . IV. Linear hypopigmentation. Alopecia, hypodontia, abnormal tooth shape, and dystrophic nails are observed. Neovascularization of the retina, present in some individuals, predisposes to retinal detachment. Neurologic findings including cognitive delays/intellectual disability and learning disability are occasionally seen. [from GeneReviews]
