}}[[rs9574]] is a SNP that can indicate haplotype H1 of the [[PROCR]] gene. The protein product of the [[PROCR]] gene activates a part of the anticoagulation pathway. While the [[rs9574]](G) allele could indicate haplotypes H2, H3 or H4, the [[rs9574]](C) allele distinctly tags (identifies) the H1 haplotype.{{PMID|17849044}}

The H1 haplotype (and thus [[rs9574]](C)) has been reported to be associated with a reduced risk of [[venous thromboembolism]] (VTE), with an odds ratio of 0.59, CI: 0.41â€“0.84.{{PMID|15116250}} Two other groups have not found this association to be statistically valid in the populations they studied.[PMID 14576048, PMID 15304035]
