Treatment

  • No psychological or psychiatric treatment is needed as the mental development of patients remains normal. Causes It is believed that the mutation of the gene Cullin 7 could lead to the disorder.[signssymptoms.org]
  • It is not in any way intended to be used as a substitute for professional medical advice, diagnosis, treatment or care. Our staff consists of biologists and biochemists that are not trained to give medical advice .[uniprot.org]
  • In general, the response to treatment is modest, however a trial of treatment over 1 year (GH doses of 35-45 microgram/kg/day with monitoring of serum IGF-I levels) may show a reasonable response. In this case, r-hGH should be continued long-term.[orpha.net]
  • 3-M syndrome is a primordial growth disorder caused by mutations in CUL7, OBSL1 or CCDC8. 3-M patients typically have a modest response to GH treatment, but the mechanism is unknown.[ncbi.nlm.nih.gov]

  • Prognosis There is currently no available data on long-term visual prognosis of Stickler syndrome; however, prophylactic treatment to prevent retinal detachment is expected to improve long term visual prognosis.[eyewiki.aao.org]

Etiology

  • Clinical description Infants present with severe postnatal (and prenatal) growth retardation, usually associated with a low birth weight ( Etiology Mutations in the CUL7 gene (6p21.1) are most often responsible for 3M syndrome (67% of cases).[orpha.net]

  • Etiology This condition, common among cyclists, is brought on by repeated training at a single, moderately hard intensity, known as Zone 3.[bicycling.com]

Epidemiology

  • Summary Epidemiology Approximately 200 cases have been reported to date but as the condition is likely under-recognized, the true figure is probably higher.[orpha.net]
  • Epidemiology Frequency United States The incidence is rare, but it is likely underreported. White patients and those of Latino descent have been described in the United States.[emedicine.medscape.com]
  • Epidemiology The incidence of the genetic disorder is 1 in 32,000 births [ 5 ] . However, higher incidences have been found in communities in which consanguineous marriages are common [ 6 ] .[patient.info]

Pathophysiology

  • […] abnormalities has moved some authorities to propose a name change to Laugier and Hunziker pigmentation. [1] When associated with nonclassic body locations or atypical features, the name idiopathic lenticular mucocutaneous hyperpigmentation has been used. [2] Pathophysiology[emedicine.medscape.com]
  • Pathophysiology Stickler syndrome is believed to be a direct result of abnormalities in the production of collagen types II, IX and XI, all of which are recognized as components of the human vitreous. [5] Normal collagen fibrils are composed of three[eyewiki.aao.org]
  • The major pathophysiologies encountered in blunt chest trauma involve derangements in the flow of air, blood, sepsis due to leakage of alimentary tract contents, as in esophageal perforations, also must be considered.[wikivisually.com]

Prevention

  • As Stickler syndrome is related to a genetic abnormality, there is no known primary prevention.[eyewiki.aao.org]
