A study in humans demonstrated that the mir-1260a was selected as a candidate from microarray and literature for semen identification [Sauer et al. DOI:10.1016/j.fsigen.2016.01.018]. In a separate human study, the mir-1260a was found to be differentially expressed and shared across two pairs of monozygotic twins, suggesting a role in distinguishing genetically identical individuals [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003].
