Table 3 MHC2TA genotype and allele frequencies in the Austrian and Swedish study populations

From: The MHC2TA-168A>G gene polymorphism is not associated with rheumatoid arthritis in Austrian patients

  Austrian cohort Swedish cohort [12]
  RA patients (n = 362) Matched controls (n = 351) Additional controls (n = 1,709) RA patients (n = 1262) Matched controls (n = 704) Additional controls (n = 1,599)
MHC2TA -168 AA genotype 184 (50.8)* 172 (49.0) 894 (52.3) 728 (57.7) 449 (63.8) 989 (61.9)
MHC2TA -168 AG genotype 155 (42.8) 142 (40.5) 669 (39.1) 451 (35.7) 221 (31.4) 528 (33.0)
MHC2TA -168 GG genotype 23 (6.4) 37 (10.5) 146 (8.5) 83 (6.6) 34 (4.8) 82 (5.1)
MHC2TA -168G allele frequency 0.278 0.308 0.281 0.244 0.205 0.216
  1. The MHC2TA genotype and allele frequencies of the present study population and the primary report by Swanberg and colleagues [12]. Carriers of a -168G allele were less frequent in the Austrian cohort compared with the Swedish cohort. *Austrian rheumatoid arthritis (RA) patients versus Swedish RA patients, P = 0.02, Austrian matched controls versus Swedish matched controls, P < 0.001, Austrian additional controls versus Swedish additional controls, P < 0.001.
