Cost-effective HLA-Cw06:02 typing in a Caucasian population.

Considering the clinical and genetic heterogeneity of psoriasis which may translate into distinct disease pathology and treatment response, correct typing of the main candidate gene HLA-C is critical but not trivial. To facilitate genotyping, we compared established techniques with our newly developed tool. Here, we propose that typing of four single nucleotide polymorphic markers within the HLA-C region correctly determines HLA-Cw*06:02 genotypes in psoriatic cases and healthy controls in a population of Caucasian origin. Typing of the SNPs presented herein proved to be precise, reliable, time and cost effective, and requiring low amount of DNA.
