Genotyping of IL-4 −590 (C>T) Gene in Iraqi Asthma Patients

Table 5

Allele frequencies of IL4 −590 (C>T) in asthma patients and controls.

Gene position	Allele	Asthma patients number (%)	Controls number (%)	OR (95% CI)	value
IL-4 −590 (C>T)		(92.71) 89	(58) 29	9.21 (IC = 3.58−23.71)
	EF	0.826
		(7.29) 7	(42) 21	0.11 (IC = 0.04−0.28)
	PF	0.374

OR = odds ratio, CI = confidence intervals, EF = etiological fraction, and PF = preventive fraction. differences at level by using Fisher’s test.
