“…Unsurprisingly, a number of contradictory results have been reported. Recently, higher prevalence of HLA-DQB1*0201/ 0302 genotype has been suggested in patients with severe retinopathy compared with those free of retinopathy [8], and the presence of HLA-A24 has also been suggested to be a risk factor for early onset retinopathy, possibly due to more rapid loss of beta-cell function associated with this allele. Whilst hyperglycaemia is important in the pathogenesis of nephropathy, early beta-cell failure is probably not a major influence on the development of nephropathy as patients with nephropathy appear to be more insulin resistant than their non-nephropathic counterparts.…”

“…This locus contains the HLA-DQ genes and other MHC-encoding genes that contribute to risk of Type 1 diabetes depending on the ethnic population investigated. This HLA region, that is located on 6p21, has also been implicated as a genomic region of interest for susceptibility to retinopathy in both Type 1 [23][24][25][26][27] and Type 2 27,28 diabetes. However, the results appear to vary based on retinopathy classification (see Table 1) and ethnicity, and could be clarified by replication in large samples of adult patients.…”

“…No entanto, não foram realizados até o presente momento, estudos de agregação familiar de RD. Além disto, os estudos que avaliam a associação de RD com etnia (89) e com o sistema HLA (90)(91)(92) , têm resultados conflitantes. De uma maneira geral os genes candidatos a serem associados à RD estão relacionados aos fatores de risco ou a prováveis mecanismos patogênicos relacionados às complicações microvasculares do DM.…”
