| pubmed-article:10857794 | pubmed:abstractText | Ankylosing spondylitis (AS) affects 0.25-1.0% of the population, and its etiology is incompletely understood. Susceptibility to this highly familial disease (lambda(s) = 58) is primarily genetically determined. There is a significant sex bias in AS, and there are differences in recurrence risk to the offspring of affected mothers and fathers, suggesting that there may be an X-linked recessive effect. We undertook an X-chromosome linkage study to determine any contribution of the X-chromosome to AS susceptibility. | lld:pubmed |
