We next extended this SL analysis to identify also co‐addiction partners of other major cancer driver genes that are also frequently mutated in specific cell contexts, and in doing so, we identified a previously reported SL interaction between ARID1A and ARID1B (Helming et al,2014), suggesting that the approach is able to recapitulate many confirmed SL interaction partners (Dataset EV14). The gene discussed is ARID1A; the disease is cancer.
