The authors suggest, p14ARF and CDKN2B‐AS1 might share a promoter, a fact supported by their discovery of a significant correlation in transcript levels of CDKN2B‐AS1 with those of p14ARF, p16INK4a, and CDKN2B in healthy tissue as well as breast tumor samples and NF1‐associated tumor samples. This evidence concerns the gene CDKN2B and neoplasm.
