This is a triallelic SNP - note that the sidebar (currently) only shows 3 of the 6 possible genotypes.
[PMID 18829218] claims that this SNP does not affect the serum concentration of CRP, while older resources seem to disagree. However, they do report an association between CRP levels and risk of abdominal aortic aneurysm (AAA).
