Hypochondrogenesis


Presentation

  • The findings presented here suggest that type II collagen may function in human cardiogenesis.[ncbi.nlm.nih.gov]
  • Most cartilage is later converted to bone, except for the cartilage that continues to cover and protect the ends of bones and is present in the nose and external ears. Prevention - Hypochondrogenesis Not supplied.[checkorphan.org]
Heart Disease
  • ., short rib polydactyly syndrome type II and chondroectodermal (Ellis-van Creveld) dysplasia, congenital heart disease has not been described in hypochondrogenesis.[ncbi.nlm.nih.gov]
Hydrops Fetalis
  • The abdomen is enlarged, and excess fluid may build up in the body before birth (a condition called hydrops fetalis).[en.wikipedia.org]
  • The abdomen is enlarged, and excess fluid may build up in the body before birth (a condition called hydrops fetalis). Prognosis - Hypochondrogenesis Not supplied. Treatment - Hypochondrogenesis There is no cure or treatment for hypochondrogenesis.[checkorphan.org]
  • Individuals with hypochondrogenesis have an enlarged abdomen and may have a condition called hydrops fetalis in which excess fluid builds up in the body before birth.[ghr.nlm.nih.gov]
  • Characterized by severe micromelia, lack of vertebral ossification, and a large head with relatively normal ossification of the calvarium; also associated with polyhydramnios, cystic hygroma, and hydrops fetalis.[mhmedical.com]
  • fetalis Treatment and prognosis The prognosis is generally poor, with most infants being stillborn or dying soon after birth.[radiopaedia.org]
Short Arm
  • Affected infants have short arms and legs, a small chest with short ribs, and underdeveloped lungs. The spinal bones (vertebrae) in the neck and part of the pelvis (the sacrum) do not harden, or ossify, properly.[en.wikipedia.org]

  • Affected infants have short arms and legs, a small chest with short ribs, and underdeveloped lungs. Bones in the skull appear normal, but the bones of the spine (vertebrae) and pelvic bones do not harden properly.[medic8.com]
  • Affected infants have short arms and legs, a small chest with short ribs, and underdeveloped lungs. Bones in the skull develop normally, but the bones of the spine (vertebrae) and pelvis do not harden (ossify) properly.[ghr.nlm.nih.gov]
Long Arm
  • Genetic profile Hypochondrogenesis is caused by a mutation, or change, in the COL2A1 gene located on the long arm of chromosome 12 (12q13.11-q13.2).[encyclopedia.com]
Hypertelorism
  • On physical examination the baby had macrocephaly, large anterior fontanelle, flat occiput, hypertelorism, depressed nasal bridge, anteverted nostrils, long philtrum, deformed low set ears, atretic ear canal, short neck, short thorax, hypertrichosis,[pediatriconcall.com]
  • Their faces have a characteristic appearance with a flat ovalshaped face, wide-set eyes (hypertelorism), small chin, and, occasionally, an infant with hypochondrogenesis will also have a cleft palate or opening on the roof of the mouth.[encyclopedia.com]
  • A 2nd or 3rd trimester three-dimensional profile may help to distinguish the normal facies of osteogenesis imperfecta type IIA from the hypertelorism and broad base nose of short-rib polydactyly 32.[iame.com]
  • Clinical evaluation showed a flat face, apparent hypertelorism, depressed nasal bridge, small upturned nose, midface hypoplasia, micrognathia, ulnar deviation of hands and club feet (Figure 6 ). Figure 6 Patient 2, 2 years.[ojrd.biomedcentral.com]
Suggestibility
  • Biochemical studies (see companion paper) suggest that this patient had a new dominant lethal disorder caused by a structural abnormality of type II collagen.[ncbi.nlm.nih.gov]

Workup

  • During the pregnancy, the woman was offered a complete workup including a cardiac, pneumological, orthopaedic and obstetric examinations every month from the 17th to the 32nd week. All parameters remained within the normal range.[ojrd.biomedcentral.com]

Treatment

  • Treatment : How to Treat "hypochondrogenesis"? There is no known treatment for hypochondrogenesis. If the condition is detected during pregnancy, parents are given the option to terminate the pregnancy.[signssymptoms.org]

  • Treatment - Hypochondrogenesis There is no cure or treatment for hypochondrogenesis. If the diagnosis is made prior to birth, the parents may wish to meet with a neonatalogist to discuss management of the birth.[checkorphan.org]
  • Treatment and management There is no cure or treatment for hypochondrogenesis. If the diagnosis is made prior to birth, the parents may wish to meet with a neonatalogist to discuss management of the birth.[encyclopedia.com]
  • Genetic disorders, such as Ehlers-Danlos syndrome, Marfan syndrome, and osteogenesis imperfecta Autoimmune disorders, such as lupus and scleroderma Cancers, like some types of soft tissue sarcoma Each disorder has its own symptoms and needs different treatment[medlineplus.gov]

Prognosis

  • Hypophosphatasia and hypochondrogenesis, in particular, have a poor prognosis. Therefore, assessment of the prognosis is the key to successful management. We report two cases of hypophosphatasia and hypochondrogenesis detected by ultrasonography.[jstage.jst.go.jp]
  • Prognosis The prognosis for an infant with hypochondrogenesis is bleak. Some infants are stillborn, and those that are live born die shortly after birth due to respiratory failure. Survival can range from a few days to a few weeks.[encyclopedia.com]

Etiology

  • Elsevier Health Sciences, ١٨‏/٠٨‏/٢٠١٣ - 979 من الصفحات Smith’s Recognizable Patterns of Human Malformation has long been known as the source to consult on multiple malformation syndromes of environmental and genetic etiology as well as recognizable disorders[books.google.com]

  • This observation further supports the conclusion that SPD and PLSD-T are not two etiologically distinct entities but belong to the same continuum phenotypic spectrum.[ojrd.biomedcentral.com]

Pathophysiology

  • Pathophysiology A series of mutations in the DDST gene has been identified in patients with achondrogenesis type IB.5, 6 Homozygosity or compound heterozygosity for these mutations, which leads to premature stop codons or structural mutations in transmembrane[odlarmed.com]

Prevention

  • Mutations in the COL2A1 gene interfere with the assembly of type II collagen molecules, which prevents bones from developing properly. This condition is caused by new mutations in the COL2A1 gene.[en.wikipedia.org]
