BACKGROUND AND PURPOSE: Genes associated with the inflammatory response and cytostructural integrity may influence recovery following a brain injury. To examine this in the setting of spontaneous intracerebral hemorrhage (ICH), selected single nucleotide polymorphisms (SNPs) were assessed for associations with patient outcome. METHODS: A cohort of 54 patients with supratentorial ICH were enrolled. Based on known involvement with neuroinflammation and cytostructural integrity, 10 preselected SNPs from 6 candidate genes were tested for associations with 6-month functional outcome (modified Rankin Scale [mRS] ≥ 3), mortality, and in-hospital deterioration (Glasgow Coma Scale decrease by >2 within 7 days of admission) following ICH. Fisher's exact test and logistic regression with adjustment for race and ICH score were performed. RESULTS: SNP rs10940495 (gp130 G/A) within the gp130 gene was the only SNP significantly associated with lower odds of an unfavorable 6-month functional outcome (odds ratio = .16 for mRS ≥ 3; 95% confidence interval, .03-.87, P = .03). Compared with major allele (A) homozygotes, minor allele (G) carriers in the IL6 signal transducer gene (gp130) locus were 84% less likely to have a poor outcome (mRS ≥ 3) at 6 months following spontaneous ICH. The SNP rs10940495 (gp130 G/A) and SNP rs3219119 (PARP-1 A/T) were associated with 6-month mortality (P = .02 and .04, respectively) only on univariate analysis. None of the SNPs examined were associated with in-hospital deterioration. CONCLUSION: In this exploratory study, SNP rs10940495 in the gp130 locus was associated with functional outcome at 6 months following spontaneous ICH. These findings, which should be validated through a larger study, suggest that inflammation plays an important role in mediating outcomes after ICH.
