Objective was to investigate whether the two single nucleotide polymorphism (rs4559 and rs324011) in STAT6 gene are associated with non-atopic asthma risk in Pakistani population.
In conclusion, our meta-analyses suggest that short GT repeats of rs71802646 in STAT6 contribute to higher risk for asthma, while rs324015 may have a protective effect on atopic asthma.
There was weak evidence to implicate the following: IL13, IFNGR2, EDN1, and VDR in asthma; IL18, TBXA2R, IFNGR2, and VDR in atopy; TLR9, TBXA2R, VDR, NOD2, and STAT6 in airway hyperresponsiveness; TLR10, IFNGR2, STAT6, VDR, and NPSR1 in atopic asthma.
For example, significant associations between markers in certain candidate genes (eg, STAT6, ADRB2, and IFNGR1) for traits such as high total IgE levels observed in resistance to extracellular parasitic disease in one population and atopic asthma in another supports the common disease/common variant model for disease.
Recently, we reported that the polymorphism of the STAT6 gene exon 1 was associated with allergic diseases, while another group studied the G2964A variant of the STAT6 gene's association with atopic asthma.
