All of the processes of embryo development are described by the term embryogenesis. The embryo is called a fetus after the completion of this stage of development. The stage of prenatal development that occurs from the end of the embryonic period until birth is called the fetal period.
Mutations in the LRP5 gene can cause juvenile primary osteoporosis. This gene provides instructions for making a protein that participates in a chemical signaling pathway that affects the way cells and tissues develop.In particular, the LRP5 protein is involved in the regulation of bone mineral density.any people with childhood-onset osteoporosis do not have a mutation in the LRP5 gene. (When its cause is unknown, the condition is often called idiopathic juvenile osteoporosis). It is likely that mutations in other genes that have not been identified are involved in this condition. Read more about the LRP5 gene.
But in general, heredity is not a major reason for osteoarthritis. In some people, osteoarthritis may be triggered by another disease, for example, Paget's disease. Although the main cause of osteoarthritis is known to be weakened bone, joint, and muscle metabolism, the precise causal mechanisms are still unknown.
