title: Association of adenylate cyclase 10 (ADCY10) polymorphisms and bone mineral density in healthy adults.
abstract: Phenotypic variation in bone mineral density (BMD) among healthy adults is influenced by both genetic and environmental factors. Sequence variations in the adenylate cyclase 10 (ADCY10) gene, which is also called soluble adenylate cyclase, have previously been associated with low spinal BMD in hypercalciuric patients. Since ADCY10 is located in the region linked to spinal BMD in our previous linkage analysis, we tested whether polymorphisms in this gene are also associated with normal BMD variation in healthy adults. Sixteen single-nucleotide polymorphisms (SNPs) distributed throughout ADCY10 were genotyped in two healthy groups of American whites: 1692 premenopausal women and 715 men. Statistical analyses were performed in the two groups to test for association between these SNPs and the femoral neck and lumbar spine areal BMD. We observed significant evidence of association (p < 0.01), with one SNP each in men and women. Genotypes at these SNPs accounted for <1% of hip BMD variation in men but 1.5% of spinal BMD in women. However, adjacent SNPs did not corroborate the association in either men or women. In conclusion, we found a modest association between an ADCY10 polymorphism and the spinal areal BMD in premenopausal white women.
