The analysis of inflammatory gene expression in RNA-seq database GTEx of healthy skin exposed to sunlight revealed that nine genes (PTGS1, DRD4, CSF3, PAFAH2, KLK13, BDKRB1, HRH3, LTB4R2, and KLK2) present the same expression profiles as for XP patients. This evidence concerns the gene PTGS1 and xeroderma pigmentosum.
