Atelosteogenesis

AOI


Presentation

  • Abstract We present a case of rhizomelic dwarfism with clinical, radiographic and histologic features in keeping with atelosteogenesis type III (spondylohumerofemoral hypoplasia).[ncbi.nlm.nih.gov]
  • We present 5 cases of a short-limb dwarfism syndrome whose manifestations overlap those of atelosteogenesis and oto-palato-digital syndrome Type II.[ncbi.nlm.nih.gov]
  • We present a case diagnosed at 21 weeks of gestation in which antenatal sonographic and post-mortem radiological findings were correlated.[ncbi.nlm.nih.gov]
  • In the present report, we describe a female newborn with classic AOI leading to early neonatal death, whose diagnostic was based on prenatal radiological findings and on the physical examination of the father.[ncbi.nlm.nih.gov]
  • Renal microcysts and abnormal branching of the pancreatic duct were also present in 1 of the fetuses, and malrotation of the caecum and retinal dysplasia involving the optic nerve were identified in the other.[ncbi.nlm.nih.gov]
Ectopia Lentis
  • lentis Isolated polycystic liver disease KBG syndrome Legius syndrome Lethal congenital contracture syndrome type 3 Li-Fraumeni syndrome Limited cutaneous systemic sclerosis MELAS syndrome Mantle cell lymphoma Marfan syndrome type 1 Maternally-inherited[csbg.cnb.csic.es]
Suggestibility
  • A common pathogenesis is suggested for atelosteogenesis type I and boomerang dysplasia. A marked excess of male fetuses with boomerang dysplasia was observed.[ncbi.nlm.nih.gov]
  • The molecular analysis of the father was crucial to suggest the diagnosis of AOI in the newborn, since she died early and there were no biological samples available.[ncbi.nlm.nih.gov]
  • This is the first documentation of survival to adulthood of an individual with this disorder, of prenatal diagnostic assessment of an affected individual, and of vertical transmission suggestive of autosomal dominant inheritance.[ncbi.nlm.nih.gov]
  • Sanger sequencing validated this variant, and genetic analysis of the patient's parents suggested a de novo occurrence of the variant.[ncbi.nlm.nih.gov]
  • Immunocytochemical analysis in HEK293 cells showed that the p.G663R mutation was localized within the cytoplasm, and not to the cell membrane, suggesting p.G663R is a loss-of-function mutation.[ncbi.nlm.nih.gov]

Treatment

  • The detailed description of this patient should contribute to earlier diagnosis of this condition; anticipation of the poor prognosis in AO1 is essential for appropriate genetic counseling of the parents and for determining postnatal treatment options[ncbi.nlm.nih.gov]

Prognosis

  • Our surviving patient further defines the radiographic features of the condition and the natural history and prognosis for physical and intellectual disability.[ncbi.nlm.nih.gov]
  • The detailed description of this patient should contribute to earlier diagnosis of this condition; anticipation of the poor prognosis in AO1 is essential for appropriate genetic counseling of the parents and for determining postnatal treatment options[ncbi.nlm.nih.gov]
  • Prognosis Prognosis is poor. Death is often due to a combination of pulmonary hypoplasia and tracheobronchomalacia early in life. The documents contained in this web site are presented for information purposes only.[orpha.net]
  • Prognosis Prognosis is poor. Death is often due to a combination of pulmonary hypoplasia and tracheobronchomalacia early in life. Last updated: 7/1/2013[rarediseases.info.nih.gov]
  • Prognosis: Lethal in utero or shortly after birth due to respiratory failure. Recurrence: In the majority of cases ( de novo mutations): no increased risk. In the rare cases of autosomal recessive inheritance: 25%.[fetalmedicine.org]

Etiology

  • We conclude that it is reasonable to consider AT-I and boomerang dysplasia as part of a spectrum, probably reflecting a common etiology.[ncbi.nlm.nih.gov]
  • Etiology Atelosteogenesis III results from missense mutations or small in-frame deletions in the FLNB gene reported in exons 2-5, 13 and 27-33 resulting in the translation of filamin B protein with altered biochemical properties.[orpha.net]
  • Etiology Atelosteogenesis I results from heterozygous mutations in exons 2-5 and 27-33 of the gene encoding filamin B ( FLNB ) located to 3p14.[orpha.net]
  • […] genetic cause, the dysplasias can be broadly grouped by the function of the protein product of the causative gene Many of the genes mutated in skeletal dysplasias encode proteins that play critical roles in the growth plate Radiographics 2008;28:1061 Etiology[pathologyoutlines.com]

Epidemiology

  • Summary Epidemiology The prevalence of AOIII is unknown. Less than 25 affected patients have been reported.[orpha.net]

  • […] prevalence of skeletal dysplasias (excluding limb amputations) is estimated at 2.14 per 10,000 births ( Am J Med Genet 1996;61:49 ) Males are primarily affected in X linked recessive disorders; otherwise, males and females are usually equally affected Pathophysiology[pathologyoutlines.com]

  • The clinical course of one child was influenced by airway instability and bronchopulmonary dysplasia that complicated intubation and prevented separation from ventilator support.[ncbi.nlm.nih.gov]
