Xeroderma pigmentosum, which is commonly known as XP, is an inherited condition characterized by an extreme sensitivity to ultraviolet (UV) rays from sunlight. This condition mostly affects the eyes and areas of skin exposed to the sun

Xeroderma pigmentosum Genetic and Rare Diseases

A-Z OF SKIN Xeroderma Pigmentosum BACK TO A-Z SEARC Xeroderma pigmentosum (XP) is a rare, autosomal recessive disorder. There is an impairment of the skin's ability to repair damage from ultraviolet (UV) light, leading to early skin changes, early sunburn, dry skin and a vastly increased tendency to develop skin tumours and eye damage from UV light Xeroderma pigmentosum (XP) is a rare, autosomal-recessive inherited disease that is found worldwide at a frequency of approximately 1:250,000. XP is caused by a deficiency in either nucleotide excision repair (NER) or postreplication repair (PRR), and is characterized by severe actinic changes leadi . Xeroderma pigmentosum: beyond skin cancer Xeroderma pigmentosum (XP) was first described in 1874 by Hebra and Kaposi. In 1882, Kaposi coined the term xeroderma pigmentosum for the condition, referring to its characteristic dry, pigmented skin. Xeroderma pigmentosum is a rare disorder transmitted in an autosomal recessive manner

Xeroderma pigmentosum (XP) is a rare inherited skin disorder characterized by a heightened sensitivity to the DNA damaging effects of ultraviolet radiation (UV). The main source of UV is the sun. XP is an autosomal recessive genetic condition caused by alterations (mutations) in nine different genes. Eight of the genes make up the. From OMIM Xeroderma pigmentosum is an autosomal recessive disorder characterized by sun sensitivity and increased skin sensitivity to UV light, as well as an increased risk of skin cancer associated with a defect in nucleotide excision repair (NER). The XPF form of XP is usually relatively mild compared to other forms. Patients with XPF tend to have later onset of skin cancer Xeroderma pigmentosum is an autosomally recessive inherited disease, which means that a faulty xeroderma pigmentosum gene comes from each parent. Carriers of the xeroderma pigmentosum trait have one xeroderma pigmentosum gene and one normal gene and do not show signs or symptoms of the disease Xeroderma pigmentosum is an autosomal recessive condition that is characterized by marked photosensitivity with the development of hyperpigmented and hypopigmented lesions, atrophy, xerosis (dry skin), telangiectasia (dilated vessels), and actinic keratoses, especially on sunexposed skin Xeroderma pigmentosum is inherited in an autosomal recessive pattern. It affects both men and women of all ethnic backgrounds. XP is estimated to occur in 1 in 1,000,000 individuals in the United States.

This means a person with xeroderma pigmentosum would need to inherit one copy of the xeroderma pigmentosum gene from each parent. The parents are known as carriers as they only carry one copy of the xeroderma pigmentosum gene and therefore do not themselves have xeroderma pigmentosum. Xeroderma pigmentosum is a genetically heterogeneous autosomal recessive disorder characterized by increased sensitivity to sunlight with the development of carcinomas at an early age. Some patients develop neurologic symptoms or a more severe clinical phenotype known as de Sanctis-Cacchione syndrome (278800) (Satokata et al., 1992)

Xeroderma Pigmentosum is a rare autosomal recessive disease affecting about 1 in 250,000 people in Europe which greatly reduces the quality of life of its sufferer. XP patients have a much greater chance of developing skin neoplasms, internal organs neoplasms or even neurological disorder due to a defective Nucleotide Excision Repair (NER) pathway xeroderma pigmentosum autosomal recessive disease that is characterized by a deficiency in the ability to repair ultraviolet damage that has material basis in autosomal recessive inheritance of DNA repair.
