Pseudoachondroplasia

Pseudoachondroplasia is a rare, inherited disorder that affects bone growth. It affects one in 30,000 people. The condition is also referred to as pseudoachondroplastic dysplasia or pseudoachondroplastic spondyloepiphyseal dysplasia. It is a form of dwarfism. People with pseudoachondroplasia have normal intelligence, head size, and facial features Pseudoachondroplasia is an inherited disorder of bone growth. It was once thought to be related to another disorder of bone growth called achondroplasia, but without that disorder's characteristic facial features Summary. Pseudoachondroplasia (PSACH) is a short-limbed dwarfing condition characterized by disproportionate short stature, normal facial features and head size, and early onset osteoarthritis; intelligence is normal. There is marked laxity in the fingers, wrists, elbows and knees. Joint pain is common at all ages; osteoarthritis occurs in.

  1. Pseudoachondroplasia is usually diagnosed during early childhood and is an inherited genetic disorder. A physical exam and diagnostic tests, including X-rays and arthrograms, are used to diagnose pseudoachondroplasia. Orthopaedic conditions of the spine and hips are also commonly seen in patients with pseudoachondroplasia
  2. Clinical characteristics: Pseudoachondroplasia is characterized by normal length at birth and normal facies. Often the presenting feature is a waddling gait, recognized at the onset of walking. Typically, the growth rate falls below the standard growth curve by approximately age two years, leading to a moderately severe form of disproportionate short-limb short stature
  3. ant disorder. It is generally not discovered until 2-3 years of age, since growth is normal at first. Pseudoachondroplasia is usually first detected by a drop of linear growth in contrast to peers, a waddling gait or arising lower limb deformities..
  4. Among people with pseudoachondroplasia, the average height of an adult male is 3 feet, 11 inches and the average height of an adult female is 3 feet, 9 inches. Some individuals develop abnormal curvatures of the spine ( scoliosis and/or lordosis) during childhood that can persist into adulthood. [1

Children with pseudoachondroplasia have a normal head size and facial features, and their intelligence is also normal. However, they are small in stature. Causes. Most cases of pseudoachondroplasia result from a gene mutation and occur in families with no history of the disorder Pseudoachondroplasia is caused by a variety of mutations in the gene encoding cartilage oligomeric matrix protein (COMP). Both disorders are characterized by short-limb dwarfism, in which the affected person's arms and legs are relatively short compared to the height of the trunk. Disorders with clinical, radiographic, and molecular features in. Pseudoachondroplasia (PSACH) (OMIM #177170) is a disproportionate dwarfing condition associated with joint abnormalities that maps to chromosome 19p12-13.1. 23 Most cases appear to have an inherited autosomal dominant trait. Affected individuals may have short, stubby fingers (brachydactyly), and bowed legs (genu varum), or knock knees.
