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). Definition. Blomstrand chondrodysplasia is an autosomal recessive disorder characterized by short limbs, polyhydramnios, hydrops fetalis, facial anomalies, increased bone density, and advanced skeletal maturation (summary by Loshkajian et al., 1997).

Blomstrand chondrodysplasia is a fatal skeletal dysplasia presenting with generalised bone sclerosis and advanced skeletal maturation. Autosomal recessive inheritance has been proposed for this disease and consanguinity increases the chances of Blomstrand chondrodysplasia in offsprings. Differentiating Blomstrand chondrodysplasia From Other
Blomstrand chondrodysplasia is a rare lethal skeletal dysplasia with presumed autosomal‐recessive inheritance. A family with 2 affected fetuses was studied.

The main findings in this lethal osteochondrodysplasia are osteosclerosis and advanced skeletal maturation. Autosomal recessive inheritance has been proposed because of … Blomstrand’s chondrodysplasia (BOCD) (OMIM 215045) is an autosomal recessive disorder caused by inactivating mutations in the PTH/PTHrP receptor (PTH1R), leading to severe developmental abnormalities. Blomstrand chondrodysplasia is associated with homozygote or compound heterozygote inactivating mutations in the PTHR1 gene. PTHR1 belongs to the class B family of seven putative transmembrane domain G protein-coupled receptors. It is equipotently activated by PTH and PTHrP, and stimulates at least two distinct second messengers, cAMP/PKA and J7 MedGenet 1993; 30: 155-157 SHORTREPORTS Alethal skeletal dysplasia withgeneralised sclerosis andadvancedskeletal maturation: Blomstrand chondrodysplasia?

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.
