HLA-B*07, HLA-DRB1*07, HLA-DRB1*12, and HLA-C*03:02 Strongly Associate With BMI: Data From 1.3 Million Healthy Chinese Adults.

Project description:Strong associations between HLA alleles and infectious and autoimmune diseases are well established. Although obesity is also associated with these diseases, the relationship between HLA and obesity has not been systematically investigated in a large cohort. In the current study, we analyzed the association of HLA alleles with BMI using data from 1.3 million healthy adult donors from the Chinese Marrow Donor Program (CMDP). We found 23 HLA alleles, including 12 low-resolution and 11 high-resolution alleles, were significantly associated with BMI after correction for multiple testing. Alleles associated with high BMI were enriched in haplotypes that were common in both Chinese and European populations, whereas the alleles associated with low BMI were enriched in haplotypes common only in Asians. Alleles B*07, DRB1*07, DRB1*12, and C*03:02 provided the strongest associations with BMI (P = 6.89 × 10-10, 1.32 × 10-9, 1.52 × 10-9, and 4.45 × 10-8, respectively), where B*07 and DRB1*07 also had evidence for sex-specific effects (Pheterogeneity = 0.0067 and 0.00058, respectively). These results, which identify associations between alleles of HLA-B, DRB1, and C with BMI in Chinese young adults, implicate a novel biological connection between HLA alleles and obesity.

HLA-B*07:02 and HLA-C*07:02 are associated with trimethoprim-sulfamethoxazole respiratory failure.

Project description:We have identified an underrecognized severe adverse drug reaction (ADR) of trimethoprim-sulfamethoxazole (TMP-SMX) associated respiratory failure in previously healthy children and young adults. We investigated potential genetic risk factors associated with TMP-SMX induced respiratory failure in a cohort of seven patients. We explored whole genome sequence among seven patients representing nearly half of all reported cases worldwide and 63 unrelated control individuals in two stages: (1) human leukocyte antigen (HLA) locus variation as several other ADRs have been associated HLA genetic variants and (2) coding variation to catalog and explore potential rare variants contributing to this devastating reaction. All cases were either heterozygous (carriers) or homozygous for the common HLA-B*07:02-HLA-C*07:02 haplotype. Despite the small sample size, this observation is statistically significant both in conservative comparison to maximum reported population frequencies (binomial P = 0.00017 for HLA-B and P = 0.00028 for HLA-C) and to our control population assessed by same HLA genotyping approach (binomial P = 0.000001 for HLA-B and P = 0.000018 for HLA-C). No gene elsewhere in the genome harnessed shared rare case enriched coding variation. Our results suggests that HLA-B*07:02 and HLA-C*07:02 are necessary for a patient to develop respiratory failure due to TMP-SMX.

HLA-DRB1*07:01 and *08:02 Alleles Confer a Protective Effect Against ACPA-Positive Rheumatoid Arthritis in a Latin American Admixed Population.

Project description:HLA-DRB1 shared epitope (SE) alleles are important genetic contributors for the risk of developing anti-citrullinated protein antibodies (ACPA)-positive rheumatoid arthritis (RA), particularly in Caucasians. We aimed to analyze the contribution of HLA-DRB1 alleles and single nucleotide polymorphisms (SNPs) within the major histocompatibility complex (MHC) region to the susceptibility to develop ACPA-positive RA in a Latin American (LA) population with admixed ancestry. A total of 289 ACPA-positive RA patients and 510 controls were enrolled in this study. The presence of HLA-DRB1*04:01, *09:01 and *10:01 was increased in ACPA-positive RA patients compared with healthy controls (p < 0.0001, p < 0.001 and p < 0.01, respectively), whereas DRB1*07:01 and *08:02 was associated with a decreased risk of ACPA-positive RA (p < 0.001 and p < 0.01, respectively). These results showed a strong correlation with estimates from studies in Asians but not in Caucasian populations. The present study describes the protective effects of the HLA-DRB1*07:01 and *08:02 alleles in ACPA-positive RA patients in a LA population for the first time. Identifying relationships between HLA-DRB1 alleles and RA is important for identifying disease associations in different ethnic groups in order to reach a better understanding of RA worldwide.
