Table 6. Frequencies of haplotypes representing the different ABO antigen alleles in ACS patients and controls.

ABO allele	SNPs			Frequency
	rs8176746	rs687289	rs507666	Patients	Controls
A1	C	A	A	0.223	0.223
A2	C	A	G	0.084	0.091
B	A	A	G	0.074	0.083
O	C	G	G	0.618	0.601

The table shows the combination of alleles at three different SNPs that represent the four major ABO antigens. The frequency for inferred antigen is shown for ACS patients and controls separately. No difference in frequency were seen between ACS patients and controls for any of the antigens (P>0.05).
