Furthermore, the absence of deregulated genes at the Bonferroni-adjusted level (except for males vs. females) between different tumor characteristics (e.g., homogeneous, heterogeneous or cystic; schwannomas from NF2 patients and sporadic; and different tumor sizes) indicate that, at least at the mRNA expression level, there are no significant differences among vestibular schwannomas based on our experiments. The gene discussed is NF2; the disease is neoplasm.
