The SNP rs7216389, which tags the 3' flanking region of ORMDL3 at 17q21 and has been associated with childhood asthma, was correlated with increased glioma risk (OR = 1.10; 95% CI: 1.01-1.19).
Here we reveal the function in sphingolipid metabolism of the ORM genes (known as ORMDL genes in humans)-a conserved gene family that includes ORMDL3, which has recently been identified as a potential risk factor for childhood asthma.
The first genome wide association study (GWAS) for childhood asthma identified a novel major susceptibility locus on chromosome 17q21 harboring the ORMDL3 gene, but the role of previous asthma candidate genes was not specifically analyzed in this GWAS.
The 6 loci (IL-13C-1112T, IL-13C1923T, IL-4 C-590T, IL-4RA 175V, FcER1B E237G and 12-ADR Q27E) make little contribution to the development of asthma in children of Chinese Han nationality.
We examined whether polymorphisms in ORMDL3 and the adjacent gasdermin-like (GSDML) gene associated with asthma in the genome-wide association study are related to childhood asthma and atopy in a Mexico City population.
Only recently a new asthma susceptibility gene (ORMDL3) has been identified by a whole genome association study, considered to be a major determinant for childhood asthma.
A common C/T polymorphism at a locus controlling ORMDL3 gene expression (rs7216389) was significantly associated with the risk of childhood asthma (P = 1.73 x 10(-12)), with a single copy of the T allele conferring an odds ratio of 1.50 (95% CI, 1.24-1.81) and 2 copies of the T allele conferring an odds ratio of 2.11 (95% CI, 1.71-2.61), respectively.
Genes located on chromosome 5q (ADRB2, IL13 and IL4) and the recently identified ORMDL3, on chromosome 17, seem to be determinants of childhood asthma.
These data indicate that only the combined analyses of genetic alterations in the IL-4/IL-13 pathway reveal its actual significance to the development of atopy and childhood asthma.
Here, we investigated the evolutionary history of a common polymorphism resulting in a T529 versus C529 change in the Cadherin-Related Family Member 3 (CDHR3) receptor which underlies variable susceptibility to rhinovirus-C infection and is associated with severe childhood asthma.
Polymorphisms in <i>CDHR3</i> rs6967330 locus (G→A) that were previously associated with childhood asthma were related to differences in CDHR3 expression and epithelial cell function.
Experimental evidence suggests that CDHR3 (cadherin-related family member 3) is a receptor for rhinovirus (RV)-C, and a missense variant in this gene (rs6967330) is associated with childhood asthma with severe exacerbations.
