Blomstrand chondrodysplasia is a rare lethal skeletal dysplasia with presumed autosomal‐recessive inheritance. A family with 2 affected fetuses was studied. One fetus demonstrated a severe skeletal dysplasia at routine transabdominal ultrasound examination at 18.5 weeks of gestation.

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).

Blomstrand chondrodysplasia

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. 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.

Chondrodysplasia Blomstrand is a rare disorder caused by mutation of the parathyroid hormone receptor resulting in the absence of a functioning PTHR1. It results in ossification of the endocrine system and intermembraneous tissues [1] and advanced skeletal maturation. An autosomal recessive lethal condition caused by inactivating mutation (s) in the PTH1R gene, encoding parathyroid hormone/parathyroid hormone-related peptide receptor. This condition is characterized by short limbs, polyhydramnios, hydrops fetalis, facial anomalies, increased bone density, and advanced skeletal maturation. [from NCI] Blomstrand’s lethal chondrodysplasia (BLC) (OMIM215045) is a rare recessive human disorder characterized by early lethality, advanced bone maturation and accelerated chondrocyte differentiation. Infants with BLC are typically born prematurely and die shortly after birth. We report a female stillborn with typical clinical, radiological, and anatomopathological features of Blomstrand chondrodysplasia.
