One of the genes involved in the pathogenesis and clinical presentation of asthma is the NR3C1 gene [(official symbol: NR3C1 provided by the HUGO Gene Nomenclature Committee (HGNC); official full name: nuclear receptor subfamily 3, group C, member 1 (glucocorticoid receptor) provided by HGNC)], which encodes the glucocorticoid (GC) receptor (GCR) (5). Here, NR3C1 is linked to asthma.
