摘要: Abstract Background Spinocerebellar ataxia type 2 is a neurodegenerative disorder caused by CAG repeat expansion in ATXN2 gene. There high clinical variability among affected patients suggesting the occurring of modifier genes influencing phenotype. Objective The objective to assess association GSTO1 rs4925 and GSTO2 rs2297235 SNPs on phenotype SCA2 patients. Methods A case-control study was performed sample 120 Cuban 100 healthy subjects. Age at onset, 60° Maximal Saccade Velocity SARA score were used as markers. determined PCR/RFLP. Results Distribution alleles genotypes nearly equal between control group not associated markers "G" allele "AG" genotype differed significantly controls. Symptomatic individuals had 2.29-fold higher chance carrying least one than controls (OR=2.29, 95% CI: 1.29–4.04). age onset (p=0.037) but or Conclusion polymorphism SCA2. Meanwhile, failed show any with markers, exception potential disease onset.
