A single homozygous nucleotide exchange in exon E3 of the gene encoding the parathyroid hormone receptor type 1 (PTHR1) was identified in an infant with Blomstrand chondrodysplasia born to consanguineous parents. This alteration changes a strictly conserved proline residue at position 132 in the rec …

Autosomal recessive inheritance has been proposed because of … 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 Chondrodysplasia, Blomstrand type The PTH1R gene encodes a parathyroid hormone / parathyroid hormone-related peptide receptor (PTH / PTHRP).

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

To our knowledge, this is the first description of opposite manifestations resulting from distinct recessive mutations in the same gene. 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. 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.
