Similar to other studies which reported them as risk factors for both LOMG in Italian populations [15,16] and MuSK+MG in Caucasian and non-Caucasian populations [18,19,23,38,39,40], DRB1*16 (specifically DRB1*16:01) and DRB1*14 (specifically DRB1*14:54) were positively associated with MG in our analysis. The gene discussed is HLA-DRB1; the disease is myasthenia gravis.
