Remarks

XPH96TMA; Turkish; obligate heterozygote; affected son is GM14867 Fibroblast and affected daughter is GM14868A; see GM15707 Fibroblast; donor subject is heterozygous for a C>T nonsense mutation in exon 8 at nucleotide 1840 (1840C>T) which converts the CGA codon of arginine at amino acid 579 to a UGA stop codon resulting in marked truncation at codon 940 in the XPC gene

613208.0007; XERODERMA PIGMENTOSUM, COMPLEMENTATION GROUP C

Identified Mutation

ARG579TER; Gozukara et al. (J. Invest. Derm. 117: 197-204, 2001) found a C-to-T transition at nucleotide 1840 in XPC exon 8, which converted arginine-579 to a stop codon (R579X). This change leads to a truncation of the XPC protein at amino acid 579 rather than at its full length of 940 amino acids.
