This study aimed to determine the association of a recent identified G2014A single nucleotide polymorphism (SNP) genotype distribution in exon 8 of the estrogen receptor in postmenopausal Thai women. A prospective study was conducted at Ramathibodi Hospital between July 2005 and July 2006. Postmenopausal Thai women, aged more than 55 years and had sustained osteoporotic hipfracture, were included. Exclusion criteria were renal and metabolic bone diseases. Age, body mass index (BMI), blood tests for metabolic bone disease, and G2014A SNP genotype, bone mineral density (BMD) were collected. The relationship between the degree of osteoporosis (normal, osteopenia, and osteoporosis) and SNP genotype was analyzed by Fisher's exact test. Sixty-five postmenopausal women with osteoporosis were included. The average age was 76.2 ± 10.9 years old, and the average BMI was 21.3 ± 3.5 kg/m2. The data expressing the genotype distribution of gene G2014A SNP were G/G 23.1%, G/A 29.2% and A/A 47.7%. There was no statistical difference between age and BMI in each genotype. Gene G2014A was associated with osteoporosis of lumbar spine, femoral neck, ward triangle, and femoral neck. It could be concluded that a G2014A SNP genotype in exon 8 of the estrogen receptor was associated with postmenopausal women who had osteoporotic hip fracture.
