HLA-B and toxic epidermal necrolysis: However, an HLA analysis showed that HLA-A*33:03 (80 patients, 50 controls; OR = 3.4, p = 2.7 × 10–3), HLA-B*44:03 (80 patients, 50 controls; OR = 12.2, p = 7.3 × 10–9), and HLA-C*07:01 (80 patients, 50 controls; OR = 6.5, p = 4.4 × 10–6) were risk alleles, and haplotypes comprising HLA-B*44:03 and HLA-C*07:01 were strongly associated with SJS/TEN with SOC in the Indian population (80 patients, 50 controls; OR = 11.0, p = 1.1 × 10–7) (Kannabiran et al., 2017).
