Ten PSA variants from unconditional analyses were either the same SNP—or correlated (r2>0.3) with a SNP—previously reported to be associated with PSA levels and/or PCa: rs4951018 (SLC45A3), rs37004 (TERT-CLPTM1L), rs10993994 (MSMB), rs12285347 (MMP7), and rs11263761 (HNF1B), as well as rs266849, rs266868, rs17632542, rs11665748 and rs6070 (KLK3–KLK2). The gene discussed is KLK2; the disease is posterior cortical atrophy.
