An environmental epigenetic study of <i><scp>ADRB</scp>2</i> 5′‐<scp>UTR</scp> methylation and childhood asthma severity

Abstract

These findings support the potential use of ADRB2 5'-UTR methylation as a biomarker of both asthma severity and risk for NO (2) -associated asthma exacerbations in children, and present the first evidence of an epigenetic link between an important environmental exposure and childhood asthma severity.
