In our study, rs72725879 (in region 2) appeared to be the leading SNP that affected the serum p2PSA level in the identified locus, 8q24.21, and it was located in the exon region of a non-coding RNA gene known as PCa-associated non-coding RNA 1 (PRNCR1). The gene discussed is PRNCR1; the disease is posterior cortical atrophy.
