title: [Polymorphisms of (CAG)n and(GGN)n repeats of androgen receptor gene among ethnic Hui and Han Chinese from Ningxia].
abstract: OBJECTIVE
  To compare the distribution of (CAG)n and (GGN)n repeats polymorphisms of androgen receptor (AR) gene between Hui and Han ethnic Chinese from Ningxia.
  
  
  METHODS
  Genotypes of above repeats were determined with DNA sequencing method.
  
  
  RESULTS
  The distribution of (GGN)n repeats was significantly different between the two ethnic groups (P< 0.01), though no such difference was detected with (CAG)n repeats (P> 0.05). Particularly, Han Chinese women carrying 23 GGN repeats were significantly fewer (48.4%) than Hui women (64.7%, P=0.01).
  
  
  CONCLUSIONS
  The distribution of GGN repeat is significantly differently among Hui and Han Chinese ethnics from Ningxia.
