A study in humans identified the mir-4674 as downregulated in whole blood of patients with recurrent myocardial infarction after percutaneous coronary intervention, with this differential expression remaining significant after false-discovery rate correction [Onuoha et al. DOI:10.1111/cts.13307]. Another human study analyzing monozygotic twins found the mir-4674 to be differentially expressed and shared across two pairs of twins, indicating its potential as a biomarker for distinguishing genetically identical individuals in forensic identification [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003].
