Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Recent studies suggested a role for pro-inflammatory mediators in frontotemporal lobar degeneration (FTLD). The objective of this study was to evaluate the association of functionally active polymorphisms in pro-inflammatory cytokine genes with the occurrence and the clinical features of the disease.', 'Using a case-control study, we compared allelic and genotypic frequencies of several polymorphisms in the interleukin (IL)-1alpha, interleukin (IL)-1beta, interleukin (IL)-6 and tumor necrosis factor (TNF)-alpha genes between 110 FTLD patients and 119 healthy controls.', 'No significant association between the examined polymorphisms and the disease was found. However, in comparison with remaining genotypes, patients carrying the T/T genotype of the IL-1beta gene showed a significantly lower age at onset of the disease. In addition, scores of the Frontal Assessment Battery were significantly modified by the IL-6 -174G>C polymorphism.
Output:
Do pro-inflammatory cytokine genes influence the clinical features of frontotemporal lobar degeneration?
