We detected increased expression of lncRNA RABGAP1L-DT-206 in NAFLD and NASH cases, with optimal cutoff values that could differentiate NAFLD/NASH cases from controls; and also to discriminate NAFLD/NASH without suspicion of advanced fibrosis from NAFLD/NASH with suspicion of advanced fibrosis cases (Figure 6). Here, RABGAP1L is linked to fibrosis.
