Summaries for Czech Dysplasia

NIH Rare Diseases : 52 The following summary is from Orphanet , a European reference portal for information on rare diseases and orphan drugs. Orpha Number: 137678 Definition A rare, genetic, primary bone dysplasia disorder characterized by early-onset, progressive pseudorheumatoid arthritis , platyspondyly, and hypoplasia/dysplasia of the third and fourth metatarsals, in the absence of ophthalmologic, cleft palate , and height anomalies. Epidemiology To date, fewer than 15 families have been reported worldwide. Clinical description The first clinical signs appearing in childhood are broad knees and flat nasal bridge, followed in late childhood and adolescence by short 3rd and 4th metatarsals (not always present), joint pain in knees and hips and later osteoarthritis of the spine, shoulder, hips, and knees. Shortening of the metacarpals may also be present. Vertebral abnormalities include mild platyspondyly, irregular end plates, and reduced intervertebral distances. Stature is within average range. Brachydactyly is restricted to metatarsals III, IV and, more variably, V. Progressive hearing loss may be associated and typically starts in early adulthood, although subclinical hearing impairment for high frequencies may be detected in children. Etiology The disorder is due to the R275C mutation in the gene COL2A1 (12q13.11). Diagnostic methods Disorder is suspected based on family history and clinical presentation, but this may be difficult to detect in early childhood. Skeletal radiographs showing platyspondyly and shortened metatarsals and metacarpals may be helpful in the diagnosis work up. Diagnosis is confirmed by genetic testing for the R275C mutation in COL2A1 . Differential diagnosis Disorders with early-onset osteoarthritis and polyarticular arthritis form the main differential diagnoses and include juvenile idiopathic osteoarthritis and mild spondyloepiphyseal dysplasia due to COL2A1 mutation with early-onset osteoarthritis. Whilst COL2A1 mutations are involved in a spectrum of skeletal dysplasias, this specific disorder is typically distinguished by the absence of cleft palate, ophthalmologic pathology and short stature . Antenatal diagnosis Genetic prenatal diagnosis is possible when the mutation has been previously identified in a family member. Genetic counseling The pattern of inheritance is autosomal dominant . The risk of transmission to offspring is 50% and there is full disease penetrance. Management and treatment Treatment is symptomatic and frequently includes hip replacement (often by the age of 40), hearing aids for hearing loss, and anti-rheumatic medication for osteoarthritis. Appropriate surveillance of hearing loss and progression of osteoarthritis is required. Prognosis The disorder is associated with early-onset, progressive arthritis that is typically associated with significant joint pain and restricted mobility that can adversely impact quality of life. Early joint replacements are often recommended. Longevity does not appear to be different to that of the general population. Visit the Orphanet disease page for more resources.

MalaCards based summary : Czech Dysplasia, also known as czech dysplasia, metatarsal type, is related to arthropathy, progressive pseudorheumatoid, of childhood and spondylarthropathy, and has symptoms including arthralgia and waddling gait. An important gene associated with Czech Dysplasia is COL2A1 (Collagen Type II Alpha 1 Chain), and among its related pathways/superpathways are PI3K-Akt signaling pathway and Focal adhesion. Affiliated tissues include bone and testes, and related phenotypes are scoliosis and flexion contracture

Genetics Home Reference : 25 Czech dysplasia is an inherited condition that affects joint function and bone development. People with this condition have joint pain (osteoarthritis) that begins in adolescence or early adulthood. The joint pain mainly affects the hips, knees, shoulders, and spine and may impair mobility. People with Czech dysplasia often have shortened bones in their third and fourth toes, which make their first two toes appear unusually long. Affected individuals may have flattened bones of the spine (platyspondyly) or an abnormal spinal curvature, such as a rounded upper back that also curves to the side (kyphoscoliosis). Some people with Czech dysplasia have progressive hearing loss.

OMIM : 56 Czech dysplasia is an autosomal dominant skeletal dysplasia characterized by early-onset, progressive pseudorheumatoid arthritis, platyspondyly, and short third and fourth toes (Marik et al., 2004; Kozlowski et al., 2004). (609162)

KEGG : 36 Czech dysplasia is an autosomal-dominant disorder characterized by an early-onset, progressive spondyloarthropathy with normal stature. Shortness of third and/or fourth toes is a frequently observed clinical feature. Czech dysplasia is caused by a specific missense mutation (R275C) in the COL2A1 gene.

UniProtKB/Swiss-Prot : 73 Czech dysplasia: A skeletal dysplasia characterized by early-onset, progressive pseudorheumatoid arthritis, platyspondyly, and short third and fourth toes.
