  1. TSC1 mutation was detected in 6 patients and TSC2 mutation in 15 patients
  2. Presented are numbers of patients who underwent genetic testing
  3. *Statistical analysis had been performed to determine correlations between genotype (TSC1 or TSC2) and phenotype (examined parameter) in consideration of the number of patients in which the examined parameter is not present. Fisher’s Exact Test was used to determine significance (p < 0.05)
  4. †Since all patients who underwent genetic testing had cortical tubers, no statistical analysis could be performed
