Table 2. SNP allele frequencies.

SNP	Gene	HD (n = 50)	CD (n = 58)	p-value
rs1800795	IL6	0.35	0.32	0.6410
rs1800797	IL6	0.35	0.32	0.6421
rs1800796	IL6	0.07	0.06	0.7660
rs4537545	IL6R	0.33	0.49	0.0175
rs2228145	IL6R	0.30	0.42	0.0679
rs10940495	gp130	0.32	0.21	0.0658
rs715180	gp130	0.09	0.09	1.0

Minor allele frequencies for each of the SNPs tested are depicted for HD and CD patients. IL6 SNPs rs1800795 and rs1800797 are in LD as are the two IL6R SNPs. There is a significant difference between the minor allele frequencies of the IL6R SNP rs4537545 for HD and CD patients (p = 0.0175).
