CDKN2B and breast neoplasm: 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.
