SPTA1 and hepatocellular carcinoma: The genomic landscape of Mongolian HCC, derived from 76 patients with HCC-associated with HBV, HCV, and HDV [72], showed previously known common driver mutations, such as TP53 and CTNNB1, but also a series of unique driver genes, most notably GTF2IRD2B, PNRC2 and SPTA1, that were not previously reported, as well as complex mutation signatures linked to Mongolian liver tumors.
