Multiple sclerosis (MS) is a common neurological disease caused by genetic and environmental factors. Previous genetic analyses have suggested that theMHC/HLA region on chromosome 6p21 contains an MS-predisposing component. Which of the many genes present in this region is primarily responsible for disease susceptibility is still an open issue. In this study, we evaluated, in a large cohort of ...
Mechanisms for observed associations within the major histocompatibility complex (MHC) and autoimmune diseases including multiple sclerosis (MS) remain uncertain. Genotyping of the HLA Class II DRB1 locus in 4347 individuals from 873 multiplex families with MS highlights the genetic complexity of this locus. Excess allele sharing in sibling pair families lacking DRB1*15 and DRB1*17 (58.5% shari...
Background Lupus nephritis (LN) is one of the main clinical challenges in systemic lupus erythematosus (SLE) and a cause significant morbidity mortality. Genetic contribution to SLE pathogenesis important, genetic profiling through polygenic risk scores has been shown useful stratify patients according dominating molecular disease mechanism. [1] This not, however, investigated for specific mani...
Autoimmune diseases (AIDs) are characterized by a multifactorial aetiology and a complex genetic background, with the MHC region playing a major role. We genotyped for HLA-DRB1 locus 1228 patients with AIDs-213 with Systemic Lupus Erythematosus (SLE), 166 with Psoriasis or Psoriatic Arthritis (Ps + PsA), 153 with Rheumatoid Arthritis (RA), 67 with Systemic Sclerosis (SSc), 536 with Multiple Scl...
Multiple sclerosis (MS) susceptibility demonstrates a complex pattern of inheritance. Haplotypes containing HLA-DRB1*1501 carry most of the genetic risk. Epidemiological evidence implicating epigenetic factors includes complex distortion of disease transmission seen in aunt/uncle-niece/nephew (AUNN) pairs. Unexpectedly, in AUNN families we found that allele frequencies for HLA-DRB1*1501 were di...
INTRODUCTION Both genetic and environmental factors contribute to rheumatoid arthritis (RA), a common and complex autoimmune disease. As well as the major susceptibility gene HLA-DRB1, recent genome-wide and candidate-gene studies reported additional evidence for association of single nucleotide polymorphism (SNP) markers in the PTPN22, STAT4, OLIG3/TNFAIP3 and TRAF1/C5 loci with RA. This study...
OBJECTIVE Five loci-the shared epitope (SE) of HLA--DRB1, the PTPN22 gene, a locus on 6q23, the STAT4 gene and a locus mapping to the TRAF1/C5 genetic region--have now been unequivocally confirmed as conferring susceptibility to RA. The largest single effect is conferred by SE. We hypothesized that combinations of susceptibility alleles may increase risk over and above that of any individual lo...
26 Background. The frequency of autoantibodies against glutamic acid decarboxylase-65 27 (GAD65), and ICA512/IA2 (IA2) are a function of the specific human leukocyte antigen 28 (HLA) in type 1 diabetes mellitus (T1D). We investigated the association of HLA class II 29 (DR, DQ) alleles and haplotypes with the presence of GAD and IA-2 autoantibodies in T1D. 30 Methods. Autoantibodies were tested ...
Genome-wide association and candidate gene studies implicate different genetic variants within the 6p21 chromosomal region with different non-Hodgkin lymphoma (NHL) subtypes. Complementing these efforts, we conducted human leukocyte antigen (HLA) class I and class II genotyping among 610 NHL cases and 555 controls of non-Hispanic white descent from a US multicenter study. Allele-disease associa...
