AB Guillain-Barre Syndrome (GBS) is considered a complex disorder with significant environmental effect and genetic susceptibility. Genetic polymorphisms in CD1E, CD1A, IL-17 and/or ICAM-1 genes had been proposed as susceptibility genetic variants for GBS mainly in Caucasian population. This study explores the association between selected polymorphisms in these genes and GBS susceptibility in confirmed GBS cases reported in mestizo population from northern Peru during the most recent GBS outbreak of May 2018. A total of 9 non-related cases and 11 controls were sequenced for the polymorphic regions of CD1A, CD1E, IL-17 and ICAM-1 genes. We found a significant protective association between heterozygous GA genotype in ICAM-1 gene (241Gly / Arg) and GBS (p <0.047). IL-17 was monomorphic in both controls and patients. No significant differences were found in the frequency of SNPs in CD1A and CD1E between the group with GBS patients and healthy controls. Further studies with larger sample size will be required to validate these findings.
