REZENDE, Patrícia Almeida de  and  ARRUDA, Walter Oleschko. Genetic aspects in multiple sclerosis: HLA system. Arq. Neuro-Psiquiatr. [online]. 1996, vol.54, n.3, pp.439-450. ISSN 0004-282X.

Review of studies about HLA antigens and multiple sclerosis (MS). The HLA system, in special class II antigens, subregions DR and DQ, is probably involved in the immunopathogenesis of MS. Haplotype DRB1*1501.DQA1*0102.DQB1*0602, corresponding to phenotype DR2.Dw2.DQ6, is positively associated with MS in several caucasoid populations. Clinical heterogeneity of MS, as well as different diagnostic criteria adopted by investigators are potential sources of confusion and may lead to discrepant results. A better standardization of clinical and laboratorial methodology, appropriate subdivision of patients with different clinical forms of MS, may allow a more accurate evaluation of the role of genetic factors in the pathogenesis of MS.
