title: Secretor status and ankylosing spondylitis.
abstract: OBJECTIVE
  To assess the genetic association between secretor status and ankylosing spondylitis (AS).
  
  
  METHODS
  A restriction digest method for determining secretor status was developed; 166 patients with AS and 216 healthy British white controls were typed for secretor status using this method.
  
  
  RESULTS
  The frequency of nonsecretors among patients with AS (47/166, 28%) was not significantly different from controls (72/216, 33%).
  
  
  CONCLUSIONS
  Secretor status does not influence susceptibility to AS.
