NIH Rare Diseases : ⁵³ The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 33067Disease definitionJansen's metaphyseal chondrodysplasia (JMC) is a very rare autosomal dominant skeletal dysplasia characterized by short-limbed short stature (due to severe metaphyseal changes that are often discovered in childhood by imaging), waddling gait, bowed legs, contracture deformities of the joints, short hands with clubbed fingers, clinodactyly, prominent upper face and small mandible, as well as chronic parathyroid hormone-independent hypercalcemia, hypercalciuria, and mild hypophosphatemia.Visit the Orphanet disease page for more resources.

MalaCards based summary : Metaphyseal Chondrodysplasia, Jansen Type, also known as metaphyseal chondrodysplasia, murk jansen type, is related to spondyloepimetaphyseal dysplasia, matrilin-3 related and extraskeletal chondroma, and has symptoms including waddling gait An important gene associated with Metaphyseal Chondrodysplasia, Jansen Type is PTH1R (Parathyroid Hormone 1 Receptor), and among its related pathways/superpathways are Signaling by GPCR and Peptide ligand-binding receptors. The drugs Angiotensin II and Angiotensin I (1-7) have been mentioned in the context of this disorder. Affiliated tissues include bone, eye and kidney, and related phenotypes are hypertelorism and osteopenia

Disease Ontology : ¹² A metaphyseal dysplasia that has material basis in mutation in PTH receptor which results in short-limbed dwarfism.

OMIM : ⁵⁷ The Murk Jansen type of metaphyseal chondrodysplasia is characterized by severe short stature, short bowed limbs, clinodactyly, prominent upper face, and small mandible. Hypercalcemia and hypophosphatemia occur despite the lack of parathyroid abnormalities (summary by Cohen, 2002). (156400)

UniProtKB/Swiss-Prot : ⁷⁵ Jansen metaphyseal chondrodysplasia: Rare autosomal dominant disorder characterized by a short-limbed dwarfism associated with hypercalcemia and normal or low serum concentrations of the two parathyroid hormones.
