Association between polymorphisms in HLA-Ⅱ genes and multiple sclerosis in Guizhou Province / 中华神经科杂志

ABSTRACT

Objective To discussed the relationship between multiple sclerosis(MS)and the genepolymorphism of HLA hoping that these results would be useful for further pathogeny studies,diagnoses,therapy and prognosis estimation of MS.Methods HLA-Ⅱ alleles in 32 patients with MS,36 nonimmunological neurological disease controls and 30 healthy controls,were identified by polymerase chain reaction-specific sequence primers(PCR-SSP)methods.Results The gene frequency of HLA-DR16 (7/32,1/36,0/30),DR11(7/32,3/36,1/30)and DQB1*0502(10/32,6/36,4/30)in patients with MS were higher than those in the 2 control groups.The gene frequency of DQB1*0601(8/32,12/36,17/30)in the patients with MS was lower than the controls.However,only the HLA-DR16 had significant difference (χ2=7.398,RR=17.94,P=0.011;χ2=5.52,RR=9.8,P=0.022).Conclusion HLA-DR16 alleles may be associated with the susceptibility to MS in Guizhou Province.
