In fine-mapping analysis of PFH and SP, we identified a total of 11 independent variants, of which eight variants (C∗06:02, C∗07:04, C∗01:02, HLA-B amino acid positions 67, 116, HLA-A amino acid position 95, DPB1∗05:01, and BTNL2:R281K) were reported to be associated with psoriasis by previous studies [18, 26–28]. The gene discussed is BTNL2; the disease is psoriasis.
