Summary:  Purpose: We attempted to confirm recent findings of Kanemoto et al. that demonstrated a positive association (p < 0.017) between a polymorphism in the promoter region of the interleukin 1-β (IL-1β) gene and the clinical phenotype of temporal lobe epilepsy with hippocampal sclerosis (TLE+HS).

Methods: We determined the frequency of this polymorphism in a group of 61 TLE+HS patients of European ancestry and compared it with that found in 119 ethnically matched control subjects.

Results: Analysis of genotype and allele frequencies showed no statistically significant difference in the distribution of the polymorphism between the two groups (p = 0.10).

Conclusions: These data suggest that this IL-1β promoter polymorphism does not act as a strong susceptibility factor for TLE+HS in a population of individuals of European ancestry.
