We describe a patient with Blomstrand chondrodysplasia, a lethal genetic disorder characterized by extremely advanced endochroncral bone maturation, in whom a homozygous missense mutation is present in the gene coding for the PTH/PTHrP receptor that leads to the substitution of a proline for a leucine in the N-terminal portion of the receptor (P132L).

I DYoung, J MZuccollo, NJ Broderick Blomstrand lethal chondrodysplasia (BLC) is a rare disorder characterized by short-limbed dwarfism with craniofacial malformations, hydrops, hypoplastic lungs, and aortic coarctation. It is classified as severe (type I) and mild (type II) forms. Notably, the skeletal features are opposite to those in Blomstrand chondrodysplasia, which is caused by inactivating recessive mutations in PTHR1. To our knowledge, this is the first description of opposite manifestations resulting from distinct recessive mutations in the same gene. Chondrodysplasia, Blomstrand type The PTH1R gene encodes a parathyroid hormone / parathyroid hormone-related peptide receptor (PTH / PTHRP). Mutations in PTH1R can cause Chondrodysplasia, Blomstrand type (BOCD; MIM 215045), Eiken syndrome (MIM 600002), Failure of tooth eruption, primary (PFE; MIM 125350) and Metaphyseal chondrodysplasia, Jansen type (MIM 156400).

Disease Ontology Browser. chondrodysplasia Blomstrand type (DOID:0060387) Alliance: disease page Synonyms: Blomstrand lethal chondrodysplasia Alt IDs: OMIM:215045 These abnormalities in Blomstrand chondrodysplasia are highly reminiscent of those seen in patients with osteopetrosis , a series of diseases characterized by a lack of osteoclastic bone resorption . They are also similar to those observed in PTHrP knockout mice that have been rescued from their neonatal deaths by the expression of a chondrocyte-specific PTHrP transgene ( 9 ).

Abstract. The clinical and and parathyroid hormone-related peptide in Blomstrand chondrodysplasia.

We report a female stillborn with typical clinical, radiological, and anatomopathological features of Blomstrand chondrodysplasia. The main findings in this lethal osteochondrodysplasia are osteosclerosis and advanced skeletal maturation. Autosomal recessive inheritance has been proposed because of parental consanguinity of affected siblings in all reported cases, including this one.

Sihem Darouich, Nadia Boujelbene, Souhir Bouzguenda, Dhikra Kacem, Radhia Ben Ghorbel, Karima Mrad and Aida Masmoudi Blomstrand chondrodysplasia is a rare lethal skeletal dysplasia, transmitted as an autsomal recessive trait. It could be a consequence of a homozygous inactivating mutation in the gene for parathyroid hormone receptors or the gene for parathyroid hormone-related peptide receptors. 2013-09-18 · Jansen chondrodysplasia is caused by constitutive activating mutations and is dominantly inherited, whereas Blomstrand chondrodysplasia is recessively inherited, caused by loss-of-function mutations. Only a single homozygous mutation has been associated with Eiken disease, and in rare cases with Ollier disease sporadic mutations in PTH1R have been found in cancer tissue.

It could be a consequence of a homozygous inactivating mutation in the gene for parathyroid hormone receptors or the gene for parathyroid hormone-related peptide receptors. 2013-09-18 · Jansen chondrodysplasia is caused by constitutive activating mutations and is dominantly inherited, whereas Blomstrand chondrodysplasia is recessively inherited, caused by loss-of-function mutations.

This chapter focuses on the role played by PTH/PTHrP Receptor Mutations in Jansen's Metaphyseal Chondrodysplasia (JMC) and Blomstrand's Lethal Name. Blomstrand syndrome; Blomstrand chondrodysplasia.

Updates to this gene will be send to {{ username }} In view of the known role played by the PTH/PTHrP receptor in bone and cartilage development, these results strongly support the conclusion that the absence of functional PTH/ PTHrP receptors is responsible for the skeletal abnormalities seen in Blomstrand chondrodysplasia, abnormalities that are the mirror image of those observed in Jansen's chondrodysplasia. 215045 - CHONDRODYSPLASIA, BLOMSTRAND TYPE; BOCD To ensure long-term funding for the OMIM project, we have diversified our revenue stream.
