In a recent work, Rotunno et al. [63] showed that the GTAATC haplotype in RNASEN, coding for Drosha, connected with lung cancer-specific reduced survival; moreover, a variant allele of rs640831 was significantly associated with RNASEN reduced mRNA expression and with changes in the levels of particular microRNAs only in adenocarcinomas but not in SqCC samples. Here, DROSHA is linked to adenocarcinoma.
