Aims:
The purpose of the study was to develop a new assay for genotyping nine single nucleotide polymorphisms (SNPs) that are known to be associated with melanoma.
Methods:
Two-stage single tube polymerase chain reaction (PCR) followed by hybridization on a biochip was developed and applied in the study.
Results:
A total of nine SNPs were selected from five genes: MC1R (rs1805006, rs1805007, rs1805009, rs11547464), HERC2 (rs12913832), OCA2 (rs1800407), SLC45A2 (rs16891982), TYR (rs1393350), and a SNP from the intergenic locus rs12896399 were used for the synthesis of ssDNAs via a single-stage PCR process. The assays were performed on a biochip-based platform that is capable of SNP genotyping via a single reaction-tube PCR, followed by on chip hybridization. We tested 69 DNAs obtained from healthy persons and demonstrated the assays' ability to discriminate all three genotypes for almost all of the SNPs.
Conclusions:
The developed approach proved robust, suggesting that it might be useful for the personalized genotyping of large cohorts of patients.
