TERT and chronic myelogenous leukemia, BCR-ABL1 positive: Additional correlation analysis conducted on CML CD34+ cells showed a statistically significant correlation between DKC1 expression and the BCR::ABL1 gene (r = 0.68 p < 0.0001) (Fig. 2g), and, interestingly, such significance was not found for TERC or TERT genes (Fig. 2e, f).
