title: [Human leucocyte antigen-DPA1 polymorphism distribution in Chengdu Chinese families with intrahepatic cholestasis of pregnancy].
abstract: OBJECTIVE
  To investigate the relationship between human leucocyte antigen (HLA)-DPA1 region gene polymorphism and intrahepatic cholestasis of pregnancy (ICP).
  
  
  METHODS
  The HLA-DPA1 alleles of 25 ICP families and 25 normal control group families were analysed by polymerase chain reaction-sequence specific primers(PCR-SSP) method.
  
  
  RESULTS
  The analysis of the frequencies and feto-maternal or couples sharing of the DPA1 alleles showed that no statistically significant difference was observed between the two study groups.
  
  
  CONCLUSIONS
  It is unlikely that an HLA-DPA1 allele is primarily associated with susceptibility or resistance to ICP.
