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

Table 6

Frequency distribution of IL4 −590 (C>T) genotypes in asthma patients and controls.

Gene	Genotype	Asthma patients number (%)	Controls number (%)	OR (95% CI)	value
IL-4 −590 (C>T)	CC	42 (87.5)	8 (32)	14.88 (IC = 4.57−48.45)	2.5 × 10^−6
	EF	0.816
	CT	5 (10.42)	13 (52)	0.11 (IC = 0.03−0.35)	3.1 × 10^−4
	PF	0.464
	TT	1 (2.08)	4 (16)	0.11 (IC = 0.01−1.03)	0.044
	PF	0.142

OR = odds ratio, CI = confidence intervals, EF = etiological fraction, and PF = preventive fraction.
