Objective To search for the genetic and molecular immunity basis of CXCR-1 associated pathogenesis in ankylosing spondylitis (AS) patients. Methods Sequencing analysis was used to detect mutation in the exonic, junctional and promoter sequences of CXCR-1 which might be related with ankylosing spondylitis; the hydrophobicity, conservation and evolutionary distance of the mutated amino acids were also analyzed. Results Six affected individuals in the family were detected with a novel mutation Arg192Gly. The glycine at 192 codon was highly conserved in different species. Arginine and glycine had quite distinct hydrophobicity and BLOSUM score. Conclusion The mutation CXCR-1 (Arg192Gly) detected in these patients might be involved in genetic and molecular immunity mechnisms of ankylosing spondylitis.
