Immunogenetics of Multiple Sclerosis in Romanian Patients: Preliminary Data

Multiple sclerosis (MS) is a chronic autoimmune disease characterized by the immune system attacking the central nervous system, leading to demyelination and neurodegeneration. This work investigates the relationship between specific human leukocyte antigen (HLA) polymorphisms and MS, aiming to reveal the immunogenetic background of this disease for more individualized management approaches. This study employed a case-control design, analyzing HLA allele frequencies in 179 MS patients and 200 control subjects using next-generation sequencing, The key findings indicate significant associations between several HLA Class I and II alleles and MS, including HLA-B*35:03:01:03, HLA-C*04:01:01:14, HLA-DRB1*15:01:01:26, and HLA-DQA1*05:05:01:02. These findings emphasize the critical role of HLA molecules in MS Romanian patients.
