PDE4DIP and mastocytosis: Four of the SNPs were more frequently found in mastocytosis patients compared to controls: rs80138802 in ABCA2 (OR = 5.739, (95% CI; 4.156–7.925), p = 1.98 × 10−27), rs11845537 in OTX2-AS1 (OR = 5.625, (95% CI; 3.859–8.199), p = 1.60 × 10−18), rs1611207 in HLA-V (OR = 2.105, (95% CI; 1.717–2.581), p = 7.25 × 10−8), and rs1778155 in PDE4DIP (OR = 2.032, (95% CI; 1.649–2.504), p = 3.26 × 10−6) genes (Table 1, Figure 1).
