Investigation of genetic risk factors for chronic adult diseases for association with preterm birth
AssociationN=1,792Nadia Falah et al.(2013)· Human Genetics

Case-control study of 673 preterm birth (PTB) cases vs 1,119 controls across four maternal cohorts testing 35 SNPs in cardiovascular, inflammatory, and metabolic disease genes. Found 13 statistically significant associations with PTB (P<0.05), more than expected by chance (binomial P=0.02). Most significant was HLA-DQA1 rs9272346 G allele protective effect in US White mothers (P=0.02, OR=0.65, 95% CI 0.46-0.94), which nominally replicated in Danish cohort (P=0.02, OR=0.85, 95% CI 0.75-0.97) but lost significance after correction for multiple testing.

Genetic association analyses of atopic illness and proinflammatory cytokine genes with type 1 diabetes
AssociationN=10,320Nada M. Saleh et al.(2011)· Diabetes/Metabolism Research and Reviews

This candidate gene association study examined genetic variants in atopic disease and proinflammatory cytokine genes for association with type 1 diabetes in 6,743-10,320 cases and 7,864-9,354 controls. The FLG R501X/rs61816761 (p=0.82), SELS -105/rs28665122 (p=0.08), and IL18 SNPs showed no association with T1D. However, four loci previously associated with asthma also showed significant association with T1D: HLA, GSDMB/ORMDL3/GSDMA (rs2305480, rs3894194, p≤1.2×10⁻⁶), and IL2RB (rs2284033, p=0.005), suggesting shared genetic susceptibility between atopic and autoimmune diseases.

About HLA-DQB1

HLA-DQB1 belongs to the HLA class II beta chain paralogs. This class II molecule is a heterodimer consisting of an alpha (DQA) and a beta chain (DQB), both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa and it contains six exons. Exon 1 encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and exon 5 encodes the cytoplasmic tail. Within the DQ molecule both the alpha chain and the beta chain contain the polymorphisms specifying the peptide binding specificities, resulting in up to four different molecules. Typing for these polymorphisms is routinely done for bone marrow transplantation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]
