miR-30 microRNA precursor is a small non-coding RNA that regulates gene expression. Animal microRNAs are transcribed as pri-miRNA (primary miRNA) of varying length which in turn are processed in the nucleus by Drosha into ~70 nucleotide stem-loop precursor called pre-miRNA (precursor miRNA) and subsequently processed by the Dicer enzyme to give a mature ~22 nucleotide product. In this case the mature sequence comes from both the 3' (miR-30) [1] and 5' (mir-97-6) [2] arms of the precursor. The products are thought to have regulatory roles through complementarity to mRNA.

A screen of 17 miRNAs that have been predicted to regulate a number of breast cancer associated genes found variations in the microRNAs miR-17 and miR-30c-1, these patients were noncarriers of BRCA1 or BRCA2 mutations, lending the possibility that familial breast cancer may be caused by variation in these miRNAs.

Members of the miR-30 family have been found to be highly expressed in heart cells. [5]
