MIR3667HG and cutaneous mastocytosis: Among the seven statistically significant RNAs, the higher the expression levels of hsa-miR-17-5p and TBC1D2 were, the greater the risk of death of CM patients (HR > 1, p < 0.05); the higher the expression levels of HLA-DQB1-AS1, C9orf139, C22orf34, SUCO and BTN3A1 were, the lower the risk of death of CM patients (HR < 1, p < 0.05; Table 2).
