A previous GWAS in Chinese population firstly identified a susceptibility locus for BA on 10q24.2 with rs17095355 as the lead single nucleotide polymorphism (SNP), which is located in the intergenic region between the X-prolyl aminopeptidase 1 (XPNPEP1) and ADD3 genes [9]. Here, XPNPEP1 is linked to breast angiosarcoma.
