USF2 and breast angiosarcoma: In the present study, we evaluated the replication results of USF2 rs916145 polymorphism in a larger case–control population with 506 cases and 1473 controls, compared with the same study conducted by Huang et al. [23] in 2008, which demonstrated that C allele and CC allele of rs916145 in USF2 gene had more frequency for developing BA in 52 BA patients and 96 healthy controls.
