A nested sequence-specific primer-polymerase chain reaction for the detection of HLA-B*15:02

In this study, we reported a new technique in detecting HLA-B*15:02 by using a nested sequence-specific primer-polymerase chain reaction (SSP-PCR) that can be used on genomic DNA and whole blood for carbamazepine hypersensitivity prediction. We tested a total of 200 blind samples with known human leukocyte antigen (HLA)-B allelic types (44 positive for HLA-B*15:02 and 156 negative for HLA-B*15:02) with this new nested SSP-PCR technique and compared its efficacy to that of commercial sequence-specific oligonucleotide probe-polymerase chain reaction (SSOP-PCR). Using starting materials from DNA and whole blood, we were able to detect HLA-B*15:02 in 44 of our samples correctly. The test is very sensitive and is highly reproducible.
