Abstract
- Objective To study the HLA of class 1and 2 in a multiple sclerosis (MS) population to verify the susceptibility for the disease in the Southern Brazil. Methods We analyzed patients with MS and controls, by direct sequencing of the genes related to HLA DRB1, DQB1, DPB1, A, B and C alleles with high resolution techniques. Results We found a lower frequency of all HLA alleles class 1 and 2 in MS and controls comparing to the European population. Several alleles had statistical correlation, but after Bonferroni correction, the only allele with significance was the HLA-DQB1*02:03, which has a positive association with MS. Conclusions Our data have different frequency of HLA-alleles than the previous published papers in the Southeast Brazil and European population, possible due to several ethnic backgrounds. RESUMO Objetivo Estudo do HLA classes 1 e 2 em pacientes com esclerose múltipla (EM) a fim de verificar a susceptibilidade para a doença em uma população do Sul do Brasil. Métodos Foram analisados por sequenciamento direto de alta resolução os genes relacionados com os HLA DRB1, DQB1, DPB1, A, B e C em casos de EM comparados com uma população controle normal. Resultados Foi encontrado uma frequência menor dos alelos dos HLA classe 1 e 2 nos casos de EM e controles quando comparado com a população Europeia. Diversos alelos mostraram correlação estatística, mas depois da correção de Bonferroni, somente o alelo do HLA-DQB1*02:03 foi positivo para a EM. Conclusões Encontramos frequência diferente dos alelos do HLA relatados previamente nos Sudeste do Brasil e Europeus, possivelmente devido a origem étnica diferente da população estuda.
