Approximately 25% of affected individuals have neurologic manifestations (acquired microcephaly, diminished or absent deep tendon stretch reflexes, progressive sensorineural hearing loss, progressive cognitive impairment, and ataxia). The most common causes of death are skin cancer, neurologic degeneration, and internal cancer. The median age at death in persons with XP with neurodegeneration (29 years) was found to be younger than that in persons with XP without neurodegeneration (37 years)." /><meta name="robots" content="index,nofollow,noarchive" />

Approximately 25% of affected individuals have neurologic manifestations (acquired microcephaly, diminished or absent deep tendon stretch reflexes, progressive sensorineural hearing loss, progressive cognitive impairment, and ataxia). The most common causes of death are skin cancer, neurologic degeneration, and internal cancer. The median age at death in persons with XP with neurodegeneration (29 years) was found to be younger than that in persons with XP without neurodegeneration (37 years). [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1397#xp.Summary" target="NBK1397">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.Diagnosis" target="NBK1397">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.Clinical_Characteristics" target="NBK1397">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.Genetically_Related_Allelic_Disorders" target="NBK1397">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.Differential_Diagnosis" target="NBK1397">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.Management" target="NBK1397">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.Genetic_Counseling" target="NBK1397">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.Resources" target="NBK1397">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.Molecular_Genetics" target="NBK1397">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.Chapter_Notes" target="NBK1397">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1397#xp.References" target="NBK1397">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />For a general description of xeroderma pigmentosum, see XPA (278700), and of Cockayne syndrome, see CSA (216400). Complementation group G has one of the smallest series of cases (Arlett et al., 1980).  <a target="_blank" href="http://www.omim.org/entry/278780">http://www.omim.org/entry/278780</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Researchers have identified at least eight genetic forms of xeroderma pigmentosum: complementation group A (XP-A) through complementation group G (XP-G), plus a variant type (XP-V). The types are distinguished by their genetic cause. All of the types increase the risk of skin cancer, although some are more likely than others to be associated with neurological abnormalities.<br /><br />About 30 percent of people with xeroderma pigmentosum develop progressive neurological abnormalities in addition to problems involving the skin and eyes. These abnormalities can include hearing loss, poor coordination, difficulty walking, movement problems, loss of intellectual function, difficulty swallowing and talking, and seizures. When these neurological problems occur, they tend to worsen with time.<br /><br />The eyes of people with xeroderma pigmentosum may be painfully sensitive to UVR (photophobia). If the eyes are not protected from UVR, they may become bloodshot and irritated, and the clear front covering of the eyes (the cornea) may become cloudy. In some people, the eyelashes fall out and the eyelids may be thin and turn abnormally inward or outward. In addition to an increased risk of cancer on the surface of the eye, xeroderma pigmentosum is associated with noncancerous growths on the eye. Many of these eye abnormalities can impair vision.<br /><br />Individuals with xeroderma pigmentosum may experience early menopause.<br /><br />Without protection from the sun and other sources of UVR, most people with xeroderma pigmentosum develop multiple skin cancers during their lifetime. These cancers occur most often on  portions of the body that are exposed to the sun, including the face, the lips, the eyelids, the surface of the eyes, the scalp, and the tip of the tongue. Studies suggest that people with xeroderma pigmentosum may also have an increased risk of some internal cancers, including brain tumors, thyroid cancer, and blood cancers. Additionally, affected individuals who smoke cigarettes have a significantly increased risk of lung cancer.<br /><br />People with xeroderma pigmentosum are 10,000 times more likely to develop non-melanoma skin cancer and up to 2,000 times more likely to  develop melanoma skin cancer compared to individuals without this condition. The types of skin cancer that can develop include basal cell carcinoma, squamous cell carcinoma, and melanoma. Most commonly, the first skin cancer appears in affected individuals before age 10. <br /><br />By age 2, almost all children with xeroderma pigmentosum develop freckling of the skin in sun-exposed areas (such as the face, arms, and lips); this type of freckling rarely occurs in young children without the disorder. In affected individuals, exposure to sunlight often causes dry skin (xeroderma) and changes in skin coloring (pigmentation). This combination of features gives the condition its name.<br /><br />The signs of xeroderma pigmentosum usually appear in infancy or early childhood. About half of affected children develop a severe sunburn after spending just a few minutes in the sun. The sunburn causes redness and blistering that can last for weeks. However, some children with xeroderma pigmentosum can tan normally. <br /><br />Xeroderma pigmentosum, commonly known as XP, is an inherited condition characterized by an extreme sensitivity to ultraviolet radiation (UVR), which is present in sunlight and may also be found in some types of artificial lighting. This condition mostly affects the eyes and areas of skin exposed to the sun. Xeroderma pigmentosum is associated with an increased risk of UVR-induced cancers. People with this condition often experience premature aging. Some affected individuals also have problems involving the nervous system.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/xeroderma-pigmentosum">https://medlineplus.gov/genetics/condition/xeroderma-pigmentosum</a></div></div>

<div class="spaceAbove">Microphthalmia is an eye abnormality that arises before birth. In this condition, one or both eyeballs are abnormally small. In some affected individuals, the eyeball may appear to be completely missing; however, even in these cases some remaining eye tissue is generally present. Such severe microphthalmia should be distinguished from another condition called anophthalmia, in which no eyeball forms at all. However, the terms anophthalmia and severe microphthalmia are often used interchangeably. Microphthalmia may or may not result in significant vision loss.\n\nPeople with microphthalmia may also have a condition called coloboma. Colobomas are missing pieces of tissue in structures that form the eye. They may appear as notches or gaps in the colored part of the eye called the iris; the retina, which is the specialized light-sensitive tissue that lines the back of the eye; the blood vessel layer under the retina called the choroid; or in the optic nerves, which carry information from the eyes to the brain. Colobomas may be present in one or both eyes and, depending on their size and location, can affect a person's vision.\n\nPeople with microphthalmia may also have other eye abnormalities, including clouding of the lens of the eye (cataract) and a narrowed opening of the eye (narrowed palpebral fissure). Additionally, affected individuals may have an abnormality called microcornea, in which the clear front covering of the eye (cornea) is small and abnormally curved.\n\nBetween one-third and one-half of affected individuals have microphthalmia as part of a syndrome that affects other organs and tissues in the body. These forms of the condition are described as syndromic. When microphthalmia occurs by itself, it is described as nonsyndromic or isolated.</div>
