The analysis results showed that the prognostic outcomes of HLH patients with TT, TC, and CC genotypes at rs385076 of the NLRC4 gene (Figure 1(a)) and the prognostic outcomes of HLH patients with CC, CG, and GG genotypes at rs479333 (Figure 1(b)) were significantly different (p < 0.01). The gene discussed is NLRC4; the disease is hemophagocytic syndrome.
