Another prevalent fusion PSMB7::SCAI (52 tumor cells) detected mostly by long reads and with four fusion splicing isoforms involves suppressor of cancer cell invasion gene SCAI. The reciprocal fusion SCAI::PSMB7 was previously detected in serous ovarian cancer cell line COV504_OVARY of the Cancer Cell Line Encyclopedia (Barretina et al. 2012), further implicating this rearrangement as of particular interest to this cancer type. Here, SCAI is linked to ovarian serous adenocarcinoma.
