Rare Variation and Remote Gene Regulation of Osteoporosis Related Phenotypes in Han Chinesse
Study Details
Study Description
Brief Summary
Bone density is recognized as the most important factor to measure osteoporosis, and the prevalence of osteoporosis increases with age. Risk factors for osteoporosis include age, weight, exercise, diet, smoking and alcohol consumption. What's more, osteoporosis has a strong familial aggregation, and the genetic value of bone density is between 0.6 and 0.85. Therefore, it is necessary to conduct large-scale collection of population samples of osteoporosis fractures and relevant genetic studies.

Detailed Description
From past linkage analysis and candidate gene association studies to genome-wide association studies and second-generation sequencing technologies, researchers have found hundreds of genes and SNPs associated with bone mineral density and osteoporosis fractures. However, current studies on osteoporosis and related phenotypes are mainly concentrated in the European and American populations, rare in Asia and other regions, and even less in the Chinese han population. It is one of the problems to be solved in this project whether the genes and SNP loci associated with these strengths can also be applied to han Chinese population due to the existence of racial differences. This project aims to collect the patients with primary osteoporosis and osteoporosis fracture in the Chinese han population through the orthopaedics department, and verify the identified osteoporosis susceptibility genes in the Chinese han population.
