|Abstract: ||Stroke is a major cause of morbidity in developed countries and therefore finding adequate treatments to promote patient’s recovery is a priority task, requiring the elucidation of the molecular pathways influencing brain recovery. Few studies, however, have assessed the role of genes in stroke outcome. This study describes a pilot genome-wide association study (GWAS) to identify genetic factors contributing to patient’s outcome, using a DNA pooling design.
Methods: Patient’s outcome was assessed using the modified Rankin Scale (mRS) three months after stroke. Using the 250K Affymetrix GeneChip Mapping Assay® – Nsp I, we compared SNP allele frequencies in a pool of non-disabled stroke patients (N=87, mRS=0), with a pool of severely disabled or deceased patients (N=100, mRS>=3). The 100 most interesting SNPs were selected for validation by individual genotyping.
Results: 36 SNPs were validated, showing significant differences between patients with extremely good and extremely poor outcome at three months (1.7x10-4 ).|
