title: [Possible association between 278C/A single nucleotide polymorphism of FKBP6 and idiopathic azoospermia].
abstract: OBJECTIVE
  To investigate 2 polymorphism sites in exon 3 and intron 2 of FKBP6 in Chinese population, while screening the gene mutations and polymorphisms in exons 3, 4 of FKBP6, and the association of these polymorphisms with azoospermia.
  
  
  METHODS
  Possible variations of exons 3, 4 and genotypes and frequencies of 2 polymorphic loci were examined by denaturing high-performance liquid chromatography(DHPLC) and PCR-restriction fragment length polymorphism(PCR-RFLP) technique in 177 azoospermia patients and 231 control individuals.
  
  
  RESULTS
  The observed allele frequencies conformed well to Hardy-Weinberg equilibrium. The frequency of 278A allele was significantly higher in controls than that in patients (P<0.05). C/T(s7797242) polymorphism was not found in either group and variations in exons 3, 4 were not detected.
  
  
  CONCLUSIONS
  278A polymorphism of FKBP6 gene was associated with idiopathic azoospermia, while C/T, 370G/A, 430G/C, 467T/C, 468G/A polymorphisms might be very rare in Chinese population.
