A study in humans demonstrated that the miR-7-2-3p was not among the 28 evaluated body fluid-specific miRNA markers used to construct a multi-class support vector machine classification model for forensic body fluid identification [Li et al. DOI:10.1016/j.fsigen.2024.103180]. A study in humans demonstrated that the miR-7-2-3p was 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].
