The ST18 -497-65050 T > C polymorphisms (rs17315309) exhibit a very strong association in the pathogenesis of Pemphigus Vulgaris (PV) and could represent a new potential molecular target for the treatment of disease. The present study aimed to establish a low-cost, sensitive and reliable assay using high-resolution melting curve analysis (HRMA) on magnetic induction rotor-based platform, the Magnetic Induction Cycler (MIC) (Bio molecular Systems). HRMA assay was able to identify easily and unambiguously the c.-497-65050 T > C genotypes evaluating melting curve shape and melting temperature (Tm). The results of HRMA were validated by direct DNA sequencing. The HRMA is rapid, sensitive, low-cost and high-throughput assay to screen the rs17315309 variant and could be used in clinical diagnostic laboratories.
