ATP6V0A2 and neoplasm: Bioinformatics analysis of the Cancer Genome Atlas (TCGA) patient data from different OVCA tumor grades (FIGO grade 1 = 2.1%, n = 42; grade 2 = 22.6%, n = 435; grade 3 = 75.1%, n = 1445) indicate that the expression of the ATP6V0A2 gene correlates with OVCA grade (G1 vs G3, P = 2.02e‐07; Fig. 1B).
