A 5-lncRNA prognostic signature (AC018645.2, LINC02454, ERICD, DSCR9, AL031770.1) was developed for STS and showed superior predictive accuracy specifically in LMS patients compared to other STS subtypes, though no individual lncRNA emerged as particularly of interest for ULMS [98]. Here, DSCR9 is linked to telomere syndrome.
