Genes affected

ERCC5 (HGNC:3437): (ERCC excision repair 5, endonuclease) This gene encodes a single-strand specific DNA endonuclease that makes the 3' incision in DNA excision repair following UV-induced damage. The protein may also function in other cellular processes, including RNA polymerase II transcription, and transcription-coupled DNA repair. Mutations in this gene cause xeroderma pigmentosum complementation group G (XP-G), which is also referred to as xeroderma pigmentosum VII (XP7), a skin disorder characterized by hypersensitivity to UV light and increased susceptibility for skin cancer development following UV exposure. Some patients also develop Cockayne syndrome, which is characterized by severe growth defects, cognitive disability, and cachexia. Read-through transcription exists between this gene and the neighboring upstream BIVM (basic, immunoglobulin-like variable motif containing) gene. [provided by RefSeq, Feb 2011]

ERCC5 links:

BIVM-ERCC5 (HGNC:43690): (BIVM-ERCC5 readthrough) This locus represents naturally occurring read-through transcription between the neighboring BIVM (basic, immunoglobulin-like variable motif containing) and ERCC5 (excision repair cross-complementing rodent repair deficiency, complementation group 5) genes on chromosome 13. The read-through transcript encodes a fusion protein that shares sequence identity with the products of each individual gene. [provided by RefSeq, Feb 2011]
