Disorders of nucleotide excision repair [DS:H00403]
Description
UV-sensitive syndrome (UV(S)S) is an autosomal recessive disorder characterized by mild photosensitivity in sun-exposed areas of the skin, with freckling and telangiectasia, but without the high propensity to skin cancer. UV(S)S and Cockayne syndrome [DS:H00076] are deficient in transcription-coupled nucleotide excision repair (TC-NER), a subpathway of nucleotide-excision repair (NER) that rapidly removes transcription-blocking DNA damage. The cellular and biochemical responses of UV(S)S and Cockayne syndrome cells to UV light are indistinguishable. Some UV(S)S cases carry mutations in the Cockayne syndrome genes ERCC8 or ERCC6 (also known as CSA and CSB, respectively).
