Introduction: Blomstrand chondrodysplasia is a very rare lethal skeletal dysplasia due to loss-of-function mutations in the gene encoding the type 1 parathyroid hormone receptor (PTHr). It is associated with resistance to PTH that results in acceleration of endochondral ossification and …

[from OMIM] Chapter 94 covers Blomstrand chondrodysplasia (MIM 215045), including major clinical findings, radiographic features, and differential diagnoses.

Blomstrand chondrodysplasia was made during pregnancy by sono- graphic examination, and was confirmed after delivery by the demon- stration of characteristic radiologic and histologic findings Blomstrand chondrodysplasia: a lethal sclerosing skeletal dysplasia. Pediatric Radiology, 1999. Henrique Lederman Abstract 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 Blomstrand chondrodysplasia is a fatal skeletal dysplasia presenting with generalised bone sclerosis and advanced skeletal maturation.

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
Autosomal recessive inheritance has been proposed because of parental consanguinity of affected siblings in all reported cases, including this one 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 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.
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.

Absence of functional receptors for parathyroid hormone and parathyroid hormone-related peptide in Blomstrand chondrodysplasia. Journal of Clinical Investigation, 1998.
Synonyms: Blomstrand lethal chondrodysplasia; Blomstrand lethal osteochondrodysplasia; BLC. 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.

Blomstrand Lethal Chondrodysplasia and Other PTH Receptor Related Disorders. 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) Definition.
