Jansen's metaphyseal chondrodysplasia is inherited in an autosomal dominant manner. Jansen's metaphyseal chondrodysplasia ( JMC ) is a disease that results from ligand -independent activation of the type 1 ( PTH1R ) of the parathyroid hormone receptor , due to one of three reported mutations (activating mutation).
Metaphyseal dysplasia, or Pyle disease, [3] is a disorder of the bones. It is a rare disease in which the outer part of the shafts of long bones is thinner than normal and there is an increased chance of fractures .
Treatment can involve operations to lengthen the leg bones, which involves many visits to the hospital. Other symptoms can be treated with medicine or surgery. Most female patients with the syndrome can live a long and normal life, while males have only survived in rare cases. [citation needed]
Hereditary multiple osteochondromas (HMO), also known as hereditary multiple exostoses, is a disorder characterized by the development of multiple benign osteocartilaginous masses in relation to the ends of long bones of the lower limbs such as the femurs and tibias and of the upper limbs such as the humeri and forearm bones.
Metaphyseal tumors or lesions include osteosarcoma, chondrosarcoma, fibrosarcoma, osteoblastoma, enchondroma, fibrous dysplasia, simple bone cyst, aneurysmal bone cyst, non-ossifying fibroma, and osteoid osteoma. [5] One of the clinical signs of rickets that doctors look for is cupping and fraying at the metaphyses when seen on X-ray.
Phytohemagglutinin. CHH is an autosomal recessive [2] inherited disorder. It is a highly pleiotropic disorder. A rarely encountered genetic phenomenon, known as uniparental disomy (a genetic circumstance where a child inherits two copies of a chromosome from one parent, as opposed to one copy from each parent) has also been observed with the disorder.
Spondyloepimetaphyseal dysplasia, Strudwick type is an inherited disorder of bone growth that results in dwarfism, characteristic skeletal abnormalities, and problems with vision. [1] The name of the condition indicates that it affects the bones of the spine (spondylo-) and two regions near the ends of bones ( epiphyses and metaphyses ).
