Relationship of lmp2 and DR3 genes with susceptibility to type I diabetes mellitus in south China Han population

Table 1 Comparison of frequencies of lmp2 genotypes and DR3 gene between I-DM patients and controls in random subjects

	n	DR3	lmp2
			R/R	R/H	H/H
1-DM	68	32(0.47)a	29(0.43)b	36(0.53)c	3(0.04)
Controls	71	15(0.21)	43(0.61)	20(0.28)	8(0.11)

Compared with controls:

^ax² = 10.44, ψ = 3.32, P < 0.0 05;

^bx² = 4.47, ψ= 0.48, P < 0.05;

^cx² = 8.86, ψ = 2.87, P < 0.005.
