For 9 of the 12 PLAG1-altered samples, we either acquired FFPE tumor tissue to perform RNA sequencing (n = 6) or molecular data from the respective collaborating institution (n = 2) or the literature (n = 1) [26] to confirm a gene fusion between either exons 4 or 5 of PLAG1 as the 3’ partner and the 5’ UTR or the initial 5’ exons of various other genes (ASAP1, ADGRG1, TMEM68, NCALD, HNRNPK, CHD7, TCF4, LOC105378102) as the 5’ fusion partner (Figure 2a, b, supplementary Figure 1). The gene discussed is ADGRG1; the disease is neoplasm.
