Short RNA molecules were considered to be junk for decades, but in recent years they have been shown to have important functional roles. MicroRNAs (miRNAs) in particular have attracted much attention. They have been assumed to be highly conserved in humans and other species; however, a recent study published in Genome Medicine reveals an unexpected level of variability in human miRNAs, including variations within the seed region. This challenges the current view of miRNAs, and may explain previous reports of pathogenic mutations in miRNAs.See research article http://genomemedicine.com/content/4/8/62/abstract. © 2012 BioMed Central Ltd.
