YR 2019 UL http://smj.org.sa/content/40/8/774.abstract AB Objectives: To investigate the relationship of 3 single nucleotide polymorphism (SNP) variants of ADAM33 with asthma susceptibility in patients from Northern and Central Punjab, Punjab, Pakistan.Methods: In this case-control study, healthy and asthmatic participants were recruited between 2015 and 2017. The SNPs of ADAM33 gene, rs2280089, rs2280090, and rs2280091 were analyzed in 296 asthma patients and 343 healthy controls, as well as linkage disequilibrium and haplotype analysis.Results: The non-significant differences were observed in allele and genotype frequencies of the SNPs in asthmatic and healthy persons even after population stratification based on age, caste, gender, family history, and environment. Although these SNPs were non-significant for disease susceptibility among children and adults, a fixed unique pattern of inheritance was nevertheless observed for the studied SNPs. Linkage disequilibrium analysis presented a very strong linkage between the SNP variants to predict their co-inheritance in study population. However, none of the haplotypes were found to be associated with asthma disease development.Conclusion: The studied SNPs of ADAM33 appeared to be non-significant for asthma susceptibility in Northern and Central Punjabi population. The fixed allele combination inheritance pattern was a unique observation contrary to findings in other global populations.
