Frequency of detectable IL-4 levels was more common in cases with year round allergy as compared to patients with seasonal allergy (OR = 0.5, P = 0.01), in cases with other co-morbidities (P = 0.02) and patients with all the differential diagnosis of Atopy (P = 0.03) (Table 3). The gene discussed is IL4; the disease is Allergy.
