Genes affected

SCGB3A2 (HGNC:18391): (secretoglobin family 3A member 2) The protein encoded by this gene is a secreted lung surfactant protein and a downstream target of thyroid transcription factor. A single nucleotide polymorphism in the promoter of this gene results in susceptibility to asthma.[provided by RefSeq, Mar 2010]
