[ Bioluminescent assay to detect melanocortin-1 receptor (MC1R) polymorphisms (R160W, R151C, and D294H)].

Several polymorphisms in melanocortin-1 receptor (MC1R) gene are shown to have associations with melanoma risk. In particular, rs1805007, rs1805008, and rs1805009 mutations causing the corresponding R151C, R160W, and D294H changes and associated with the phenotype ("red-hair mutations") are connected with melanoma and non-melanoma skin cancer risks. The work describes the approach to detect these polymorphisms based on primer extension reaction with the following dual bioluminescent assay. Model plasmids with polymorphic MC1R fragments as well as several clinical DNA samples were tested using the developed technique. The results were in good correlation with those obtained by Sanger sequencing.
