Table 3. Significance of association of candidate genes with disease was examined by Student's t-test.

	Student's t-test (P-value)
Genes/Function	GC vs. PUD	GC vs. NUD
Membrane Protein GC26_77	0.000**	0.390
Hypothetical ATPase Protein GC26_69	0.000**	0.000**
Hypothetical protein GC26_73	0.000**	0.000**
Outer membrane protein GC26_66 (type 1)	0.282	0.005**
Phospho-2-Dehydro-3-Deoxyheptonate Aldolase	0.308	0.000**
Hypothetical protein GC26_33	0.022*	0.000**

*. P-value <0.05 is considered significant.

**. P-value <0.01 is considered highly significant.
