A study in primates demonstrated that the SNAR-H is a small non-coding RNA located on chromosome 2, derived from a major duplication pathway and retaining 5DX flanking sequence [Parrott et al. DOI:10.4161/mge.18478]. Research in human genomic analysis found the SNAR-H is present in the human genome, though its transcription status was not determined experimentally [Parrott et al. DOI:10.1093/nar/gkq856].
