Osteoporosis susceptibility is strongly genetic, influenced by bone mineral density and fracture risk. While many genes are identified, most genetic factors regulating bone health remain undiscovered.
Area of Science:
- Genetics
- Bone Biology
- Osteoporosis Research
Background:
- Osteoporosis is a prevalent condition marked by low bone mass and microarchitectural defects, leading to increased fracture risk.
- Bone mineral density (BMD) and other fracture determinants exhibit high heritability, as evidenced by twin and family studies.
- Genetic factors interact with environmental influences like diet and exercise to determine osteoporosis susceptibility.
Purpose of the Study:
- To review the progress in identifying genetic factors contributing to bone mineral density (BMD) and fracture risk.
- To highlight the methodologies used in discovering genes associated with bone metabolism.
- To underscore the ongoing need for further genetic research in osteoporosis.
Main Methods:
- Analysis of rare Mendelian bone diseases with major bone mass abnormalities to identify large-effect genes.
- Genome-wide association studies (GWAS) to detect common genetic variants with small effect sizes influencing BMD and fracture risk.
- Integration of findings from genetic studies to understand the regulation of bone metabolism.
Main Results:
- Identification of numerous genes and loci regulating BMD, some previously unsuspected in bone metabolism.
- Discovery of both large-effect variants in rare diseases and small-effect variants in the general population.
- Significant advancements in understanding the genetic architecture of osteoporosis over the past 15 years.
Conclusions:
- Substantial progress has been made in identifying genes linked to BMD and fracture risk.
- The majority of genetic variants influencing these osteoporosis-related phenotypes are yet to be discovered.
- Continued genetic research is crucial for a comprehensive understanding and potential treatment of osteoporosis.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
