Aim: To construct a simple, low-cost typing method for the surrogate marker of HLA-A∗31:01, a risk factor for carbamazepine (CBZ) related Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). Materials and methods: DNAs from Japanese SJS/TEN patients were used for genotyping and developing the assay. Results: HLA-A∗31:01 was confirmed to be significantly associated with definite/probable cases of CBZ-related SJS/TEN (p = 0.0040). Three single nucleotide polymorphisms, rs1150738, rs3869066 and rs259945, were in absolute linkage disequilibrium with HLA-A∗31:01 in 210 Japanese SJS/TEN patients. Robust genotyping of rs3869066 in ZNRD1-AS1 was developed using polymerase chain reaction-restriction fragment length polymorphism assays. Conclusion: Single nucleotide polymorphism genotyping is less time consuming and cheaper than conventional HLA typing, and would be useful for identifying Japanese patients at risk of CBZ-related SJS/TEN.
