The GSE21610 dataset identified CCND1 (AUC = 0.954) and NAP1L3 (AUC = 0.877) as biomarkers with effective values for diagnosing HF, as shown in Fig. 7A. Similarly, the genes CCND1 and NAP1L3 showed robust predictive capacity for IPF (Fig. 7B). This evidence concerns the gene CCND1 and hydrops fetalis.
