Polymorphisms and haplotypes of the chromosome locus 17q12-17q21.1 contribute to adult asthma susceptibility in Slovenian patients.

One of the major asthma susceptibility loci is 17q12-17q21.1, but the relationship between this locus and adult asthma is unclear. Association analysis of 13 single nucleotide polymorphisms (SNPs) and haplotypes from 17q12-17q21.

Let-7a is differentially expressed in bronchial biopsies of patients with severe asthma.

Asthma is a chronic inflammatory disease. Around 5 to 10% of patients classified as having severe asthma can-not be adequately controlled despite the use of all currently available therapeutic approaches. Previous studies have revealed the potential important role of miRNAs in the regulation of a variety of inflammatory processes, including asthma.

Asthma treatment outcome in adults is associated with rs9910408 in TBX21 gene.

Inhaled corticosteroids (ICS) are one of the most commonly used asthma therapies and have highly variable treatment success. Polymorphisms in TBX21, a gene important for the biological action of corticosteroids, could be associated with treatment response in asthmatics. We genotyped for rs9910408 in TBX21 in 208 adult asthmatic patients, treated at least 3 years with ICS.
