XPC (Q01831) variants and mutations

XPC (also known as Q01831) is a human protein-coding gene encoding a DNA repair protein complementing XP-C cells protein. It detects helix-distorting lesions throughout the genome and initiates global-genome nucleotide-excision repair. Biallelic loss-of-function variants cause xeroderma pigmentosum group C with severe ultraviolet sensitivity and greatly increased skin-cancer risk. This analysis covers 1,468 XPC variants and mutations. Of these, 72% have computational variant effect predictions. Disease context includes Xeroderma pigmentosum complementation group C, xeroderma pigmentosum group C, and xeroderma pigmentosum. Example XPC variants include M1K, M1L, and M1R.
