Abstract

We examined whether a -34T --> C polymorphism of the gene for cytochrome P450, family 17, subfamily A, polypeptide 1 (CYP17A1), a -493G --> T polymorphism of the microsomal triglyceride transfer protein gene (MTP), and a CGG repeat polymorphism of the very low density lipoprotein receptor gene (VLDLR) were associated with bone mineral density (BMD) in community-dwelling Japanese women and men. The -34T --> C polymorphism of CYP17A1 was associated with BMD in postmenopausal women, with the CC genotype being related to increased BMD. The -493G --> T polymorphism of MTP was associated with BMD in premenopausal women, with the TT genotype being related to increased BMD. The CGG repeat polymorphism of VLDLR was associated with BMD in men, with two (CGG)(n > or= 8) alleles being related to increased BMD. These results suggest that CYP17A1 and MTP are susceptibility loci for increased BMD in postmenopausal and premenopausal Japanese women, respectively, and that VLDLR constitutes such a locus in Japanese men.
