Association of LRP5 gene polymorphism with type 2 diabetes mellitus and osteoporosis in postmenopausal women.

ABSTRACT: This study was to explore the association of low-density lipoprotein receptor related protein 5 (LRP5) gene polymorphism with bone mineral density (BMD), bone turnover markers and glycometabolism in postmenopausal women with type 2 diabetes mellitus (T2DM) and/or osteoporosis (OP) in Shanghai. 354 unrelated Han Chinese post-menopausal women were recruited from Shanghai and divided into 4 groups: OP group (n=90), T2DM group (n=96), T2DM + OP group (n=90) and control group (n=78). The LRP5 genotypes were determined by DNA sequencing. The BMD was measured by dual-energy X-ray absorptiometry. The bone transformation indicators and glycometabolism index (HbA1c and Fasting insulin) were also detected. The association of LRP5 polymorphism with BMD, bone turnover markers and glycometabolism was evaluated. Result showed that, In OP group, the BMD of L2-4 was higher in patients with rs3736228 CC genotype than those with CT/TT genotypes (P<0.05). After adjustment for age, body mass index (BMI) and years of menopause, A1330V polymorphism was still associated with BMD of L2-4 (P<0.01). In the control group, HbA1c was significantly higher in patients with A1330V CC genotype than those with CT/TT genotypes (P<0.05), but no significant difference was found after adjustment for BMI, age and years of menopause (P>0.05). Thus, LRP5 gene is an impressionable gene in postmenopausal women with OP in Shanghai. T2DM patients have a high BMD when compared with controls, which may be related to BMI and FINS. LRP5 genotype is not an impressionable gene in postmenopausal women with T2DM in Shanghai.
