Mutations in the parathyroid hormone receptor PTH1R can be seen in skeletal dysplasias such as Murk Jansen metaphyseal chondrodysplasis [44], Blomstrand chondrodysplasia [45], Eiken skeletal dysplasias [46] and primary failure of tooth eruption [47] but thus far are not linked to parathyroid adenomas or carcinomas [48]. Here, PTH1R is linked to skeletal dysplasia.
