title: Beta-2-Adrenergic Receptor Methylation Influences Asthma Phenotype in The School Inner City Asthma Study.
abstract: Asthma is the most common chronic illness of childhood and inner city residents suffer a disproportionately high rate of asthma diagnosis and asthma morbidity. The School Inner City Asthma Study investigates the school classroom based environmental exposures that may lead to asthma morbidity in inner city school children with asthma. Within this cohort, we investigated the role of methylation at the promoter region of the beta-2-adrenergic receptor in relation to asthma morbidity. We found that high levels of methylation in the region studied was significantly associated with decreased report of dyspnea and trended towards significance for lower levels of asthma symptoms and airway obstruction. This Research Highlight discusses the findings of the recent study and the investigators' active research endeavors.
