Abstract excerpt
The LRP4 gene encodes the highly conserved low-density lipoprotein receptor-related protein 4 (LRP4), which acts as a co-receptor for sclerostin. Sclerostin and LRP4 negatively regulate WNT/β-catenin signaling pathway and lack of their inhibitory activity leads to constant osteoblastic differentiation. Consequently, increased bone formation occurs, which in the case of LRP4 mutations results in sclerosteosis type...
