Forensic Context

A study in humans demonstrated that the mir-4731-5p is a differentially expressed microRNA shared across three pairs of monozygotic twins, as identified through miRNA microarray analysis of blood samples and validated by qRT-PCR, indicating its potential role in distinguishing genetically identical individuals for forensic identification [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003].
