A dissertation submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in fulfdment of the requirements for the degree of Doctor of Philosophy / Asthma is a complex syndrome which has a significant inflammatory basis which results from the complex interactions between heterogenous genetic and environmental factors. Although the environmental allergens are fairly well known, little information concerning the genetic differences between atopic and non-atopic individuals is available. Alpha-1 antitrypsin is the archetypal member of the serine proteinase inhibitor or serpin superfamily and the most important proteinase inhibitor in the lung with specificity to neutrophil elastase. Genetic deficiency of the protein is classically associated with early onset emphysema, bronchiecstasis, panniculitis, rheumatoid arthritis and glomerulonephritis. The S(E264V), Z(E342K), Ml (213 Ala) and M2 (R101H) variants of alpha-1 antitrypsin have been implicated in the pathogenesis of asthma. A novel finding was the identification of 2 new variants, the M1E(JOhannesburg) and the M IN(johannesburg) associated with asthma in individuals from South Africa / IT2018
