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.
