Transcriptomics has been characterised by the development of new techniques which have redefined what is possible every decade or so and rendered previous technologies obsolete. The first attempt at capturing a partial human transcriptome was published in 1991 and reported 609 mRNA sequences from the human brain.[1] In 2008, two human transcriptomes, composed of millions of transcript-derived sequences covering 16,000 genes, were published,[3][4] and by 2015 transcriptomes had been published for hundreds of individuals.[5][6] Transcriptomes of different disease states, tissues, or even single cells are now routinely generated.[6][7][8] This explosion in transcriptomics has been driven by the rapid development of new technologies with improved sensitivity and economy.[9][10][11][12]
