Table 4 Genotypes of IL1B -31C>T and TNFA -308G>A in Thai malaria patients.

From: A functional polymorphism in the IL1B gene promoter, IL1B -31C>T, is not associated with cerebral malaria in Thailand

  TNFA -308G>A
  G/G G/A A/A
Mild malaria (n = 192)    
IL1B -31C>T    
C/Cb 48 (0.250) 7 (0.036) 0 (0.000)
C/T 85 (0.443) 6 (0.031) 0 (0.000)
T/T 43 (0.224) 3 (0.016) 0 (0.000)
Cerebralmalaria (n = 105)    
IL1B -31C>T    
C/C 25 (0.238) 2 (0.019) 0 (0.000)
C/T 41 (0.390) 8 (0.076) 0 (0.000)
T/T 25 (0.238) 3 (0.029) 1 (0.009)
  1. Frequencies are in parentheses.
  2. There was no significant difference in each genotype frequency between mild and cerebral malaria by the Fisher's exact test based on 2 × 2 contingency table where all the other genotypes are combined.
