In the HGSOC data set, the mtSNVs were called in most cancer and noncancer cells, and some fusion calls were expressed in most clones or subclones (P2: IGF2BP2::TESPA1, P1: SMG7::CH507-513H4.1, etc.), making them ideal variations for cell type reannotation and clustering. The gene discussed is TESPA1; the disease is cancer.
