UVDR
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.

Forensic Context
A study in a Chinese Han population demonstrated that the ERCC5 level in peripheral blood, quantified via SYBR qPCR, declined with individual age with a strong negative correlation (r = -0.8), enabling the establishment of an age estimation model (Y = -31.352X + 14.436 ± 10.28) with an accuracy of approximately 73.33% and a mean absolute difference of 8.22 years [Deng et al. DOI:10.1016/j.legalmed.2021.101912]. In a separate study in C57BL mice, microarray analysis identified the ERCC5 as one of several DNA repair genes previously reported to be upregulated in radiation-resistant cell lines, though its specific expression change was not measured in this irradiation experiment [Dai et al. DOI:10.1080/09553000600857389].
