Xeroderma Pigmentosum in Children: Report of 4 Cases

Xeroderma pigmentosum: a case report.

This paper presents a case study of a child with xeroderma pigmentosum (XP). The disease results in sensitivity to UV radiation as a result of reduced activity in a defective enzyme responsible for DNA repair. Affected individuals have a variety of clinical symptoms, which may include problems of the skin and oral mucosa, ocular manifestations, and neurologic impairment. A number of precautions...

ERCC 4 ( xeroderma pigmentosum , complementation group F )

Xeroderma pigmentosum group F complementing factor; DNA-repair protein complementing XPF cells 905 amino acids; form a stable complex with the ERCC1 protein; The XPF protein and the ERCC1 protein form a complex that exhibits structure specific endonuclease activity that is responsible for the 5' incision during the NER reaction. XPF-ERCC1 also binds to XPA (through ERCC1) and to RPA (through XP...

Xeroderma pigmentosum.

Seven cases of XP seen during a relatively short period of time, possibly indicate a high frequency of this gene in this part of the country. The gene frequency in the general population has been reported to be 1 in 200 million and the frequency of the disorder, 4 in 1 million(3). Countries like Libya, Egypt, Israel and Japan, with a high degree of consanguinity, have a high incidence of this d...
