Summaries for Metatropic Dysplasia

NIH Rare Diseases : 50 metatropic dysplasia is a skeletal disorder characterized by short stature, shortened arms and legs, and a long narrow chest. the signs and symptoms of this condition can vary from life threatening to mild. signs and symptoms may include worsening abnormal curvature of the spine (scoliosis and kyphosis), flattening of the bones of the spine (platyspondyly), and restriction of certain joints in the body. some individuals are additionally born with an elongated tailbone known as a coccygeal tail. metatropic dysplasia is caused by mutations in the trpv4 gene and is inherited in an autosomal dominant manner. although there is no specific treatment or cure, there can be ways to manage the symptoms. a team of doctors is often needed to figure out the treatment options based on each person’s symptoms. last updated: 6/12/2017

MalaCards based summary : Metatropic Dysplasia, also known as metatropic dwarfism, is related to kniest dysplasia and atelosteogenesis, type i, and has symptoms including scoliosis, high forehead and hydrocephalus. An important gene associated with Metatropic Dysplasia is TRPV4 (Transient Receptor Potential Cation Channel Subfamily V Member 4). Affiliated tissues include bone, lung and trachea.

Genetics Home Reference : 25 Metatropic dysplasia is a skeletal disorder characterized by short stature (dwarfism) with other skeletal abnormalities. The term "metatropic" is derived from the Greek word "metatropos," which means "changing patterns." This name reflects the fact that the skeletal abnormalities associated with the condition change over time.

OMIM : 54
Metatropic dysplasia (MD) is characterized by short limbs with limitation and enlargement of joints and usually severe kyphoscoliosis. Radiologic features include severe platyspondyly, severe metaphyseal enlargement, and shortening of long bones (Genevieve et al., 2008). (156530)

UniProtKB/Swiss-Prot : 71 Metatropic dysplasia: A severe spondyloepimetaphyseal dysplasia characterized by short limbs with limitation and enlargement of joints and usually severe kyphoscoliosis. Radiologic features include severe platyspondyly, severe metaphyseal enlargement and shortening of long bones.
