PCAT7 and posterior cortical atrophy: We retained several contigs embedded into already annotated PCa associated lncRNA genes, such as CTBP1-AS (ctg_25348, P10), PCAT7 (ctg_111158, P6), and PCAT1 (ctg_105149, P18), or lncRNAs referenced elsewhere as ctg_104447 (P11) mapped into LOC283177, ctg_123090 (P5) into AC004066.3, and ctg_73782 (P8) into LINC01006. It should be noted that the GENCODE referenced genes enclosing these new subsequences also showed differential expression when counting on the whole gene annotation (Fig S3B).
