title: The analysis of clinical manifestations and genetic mutations in Chinese boys with primary adrenal insufficiency.
abstract: OBJECTIVE
  To analyze the clinical manifestations of primary adrenal insufficiency in Chinese boys, to investigate the prevalence of DAX1 and SF1 gene mutations, and to explore the association between gene mutations and clinical manifestations.
  
  
  METHODS
  A total of 25 boys with primary adrenal insufficiency were enrolled. Mutational analysis of the DAX1 and SF1 genes was done by direct sequencing.
  
  
  RESULTS
  DAX1 gene mutations were found in 40% (10 of 25) of 46,XY phenotypic boys referred with adrenal insufficiency, and six of these were novel. One SF1 gene mutation was identified. These patients demonstrated diverse clinical presentations. There was no definite association between clinical manifestations and genetic mutations.
  
  
  CONCLUSIONS
  DAX1 gene mutations are a relatively frequent cause of primary adrenal insufficiency. In contrast, mutation in the SF1 gene is seldom found. There is no definite relationship between gene mutations and clinical manifestations.
