Abstract
Objective: Prevalence of vitamin D receptor gene polymorphism in children suffering from pneumonia in Lahore, Pakistan.
Methodology: This cross-sectional study included 189 children aged 6-24 months. We analyzed four single nucleotide polymorphisms of vitamin D receptor: rs2228570 (Fokl), rs1544410 (Bsml), rs7975232 (Apal) and rs731236 (Taql) for their association with pneumonia using RFLP-PCR.
Results: The results showed that frequency of AC genotype of Apal (rs7975232) (OR=3.65, p=0.002) and AG genotype of Fokl (rs2228570) (OR=2.90, p=0.03) were approximately three times more common in malnourished children suffering from pneumonia.
Conclusion: The association of Apal and Fokl polymorphisms in malnourished children indicated an alteration in the functioning of the immune system, thereby increasing the susceptibility to pneumonia. These findings suggest robust treatment for these children to overcome this deficiency.

Key words: VDR – vitamin D receptor, SNPs – single nucleotide polymorphisms, pneumonia, malnourishment.
