A single-tube multiplex real-time PCR for genotype by detecting highly specific SNPs.

is closely related to carbimazole/methimazole-induced agranulocytosis. This study aimed to develop and validate a rapid and economical method for genotyping. A single-tube multiplex real-time PCR detection system comprising amplification refractory mutation system primers and TaqMan probes was established for genotyping. Sequence-based typing was applied to validate the accuracy of the assay. The accuracy of the assay was 100% for genotyping. The detection limit of the new method was 0.05 ng DNA. The positive rate of in the Han (8%, n = 100), Bouyei (17.8%, n = 90) and Tibetan (12.7%, n = 110) populations was significantly higher than that in the Uighur population (1%, n = 100) (p < 0.05). The proposed method is rapid and reliable for screening in a clinical setting.
