<jats:title>Abstract</jats:title><jats:p>Identification of cell fate-controlling lncRNAs is essential to our understanding of molecular cell biology. Here we present a human genome-scale forward-genetics approach for the identification of lncRNAs based on gene function. This approach can identify genes that play a causal role, and immediately distinguish them from those that are differentially expressed but do not affect cell function. Our genome-scale library plus next-generation-sequencing and bioinformatic approach, radically upscales the breadth and rate of functional ncRNA discovery. Human gDNA was digested to produce a lentiviral expression library containing inserts in both sense and anti-sense orientation. The library was used to transduce human Jurkat T-leukaemic cells. Cell populations were selected using continuous culture ± anti-FAS IgM, and sequencing used to identify sequences controlling cell proliferation. This strategy resulted in the identification of thousands of new sequences based solely on their function including many ncRNAs previously identified as being able to modulate cell survival or to act as key cancer regulators such as <jats:italic>AC084816.1</jats:italic>*, <jats:italic>AC097103.2</jats:italic>, <jats:italic>AC087473.1</jats:italic>, <jats:italic>CASC15*</jats:italic>, <jats:italic>DLEU1</jats:italic>*, <jats:italic>ENTPD1-AS1</jats:italic>*, <jats:italic>HULC</jats:italic>*, <jats:italic>MIRLET7BHG</jats:italic>*, <jats:italic>PCAT-1</jats:italic>, <jats:italic>SChLAP1</jats:italic>, and <jats:italic>TP53TG1</jats:italic>. Independent validation confirmed 4 out of 5 sequences that were identified by this strategy, conferred a striking resistance to anti-FAS IgM-induced apoptosis.</jats:p>
