The highest incidence of LOH and MI was found on chromosome 14q. Mean immunoglobulin E and blood eosinophil levels were significantly higher in asthmatics with three or more genetic alterations. A high incidence of genetic alterations in the deoxyribonucleic acid of the sputum cells was found in asthmatic patients. Further studies are needed to identify the role of loss of heterozygosity and microsatellite instability in the investigation of genetic susceptibility of asthma and thus, in its pathogenesis.}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/22/6/951}, eprint = {//www.qdcxjkg.com/content/22/6/951.full.pdf}, journal = {European Respiratory Journal} }
