Abstract:
:Based on the fact that the klotho-deficient mouse exhibits multiple aging phenotypes, including osteopenia and subchondral sclerosis of joints, we explored the possibility of whether human klotho gene polymorphism is associated with two major age-related skeletal disorders: osteoporosis and spondylosis. Analysis of the CA repeat sequence downstream of the final exon of the klotho gene identified ten types of alleles in Japanese postmenopausal women (n = 377). We investigated the association of this microsatellite polymorphism with bone density and spondylosis score of the lumbar spine. None of the genotypes was associated with bone density in the overall population (n = 377; 754 alleles) nor in the subpopulation at not more than 10 years after menopause ( journal_name journal_title authors doi subject pub_date pages issue eissn issn pii journal_volume pub_type
