Given that the expression level of SFT2D2‐TBX19 was significantly lower than that of TBX19, and TBX19 itself was observed to promote prostate cancer development, we speculated that the SFT2D2‐TBX19 lncRNA may possess distinct molecular functions beyond encoding TBX19‐202. The gene discussed is SFT2D2; the disease is prostate carcinoma.
