Campomelic Dysplasia

Campomelic Dwarfism


Presentation

  • We present such a case in a 1-month-old child with typical skeletal abnormalities, whose presentation was unusual because of later presentation of respiratory distress and lack of genitourinary abnormalities.[ncbi.nlm.nih.gov]
Turkish
  • A 15 day old Turkish boy presented with a small flat face, dolicocephalic head, proptotic eyes, short neck, low-set ears and a small thoracic cage. Limbs were mesomelically short and bilateral talipes equinovarus was present.[ncbi.nlm.nih.gov]
Poor Feeding
  • He also required a gastrostomy for poor feeding. Figure 2 Patient 2 aged 3.5 years. At 3½12 years, his height was 92 cm ( 97th centile). There was moderate global developmental delay.[jmg.bmj.com]
Stridor
  • There have been recurrent upper and lower respiratory infections and persistent mild stridor. There was mild developmental delay, particularly affecting gross motor development.[jmg.bmj.com]
Failure to Thrive

High Arched Palate
  • There was a high arched palate but no cleft palate. On examination, her height was 119 cm ( Figure 9 Patient 5 aged 21 years. She had many complications with recurrent apnoea and chest infections.[jmg.bmj.com]
Sparse Hair
  • Note in a the sparse hair, short nose microstomia, short neck, and in b the hypoplastic nails, and in c and d the triangular face, slightly down-turned palpebral fissures, low-set and posteriorly rotated ears, long philtrum, thin upper lips, everted lower[doi.org]
Hypoplastic Nails
  • Note in a the sparse hair, short nose microstomia, short neck, and in b the hypoplastic nails, and in c and d the triangular face, slightly down-turned palpebral fissures, low-set and posteriorly rotated ears, long philtrum, thin upper lips, everted lower[doi.org]
Congenital Short-Limbed Dwarfism
  • Campomelic dysplasia (CD; OMIM #114290), a rare form of congenital short-limbed dwarfism, is due to mutations in SOX9, a member of the SOX (SRY-related HMG box) gene family.[ncbi.nlm.nih.gov]
Large Anterior Fontanels
  • Macroscopical synopsis systemic anomalies short limb dwarfism, prenatal onset birth length 35-49 cm low-normal range birth weight failure to thrive in survivors polyhydramnios ( /- 30%) craniofacial anomalies large anterior fontanelle macrocephaly enlarged[humpath.com]

Treatment

  • Management and treatment Treatment is symptomatic. Prognosis Newborns suffering from campomelic dysplasia often die soon after birth as a result of respiratory insufficiency, but 5 to 10 % of individuals survive.[orpha.net]
  • As a result of improvements in respiratory care, some patients survive into childhood, requiring treatment of their spinal deformities.[ncbi.nlm.nih.gov]
  • Campomelic Dysplasia Treatment Camptomelic Dysplasia is a life-threatening disorder for the newborns. It is characterized by the presence small lungs and chest. The size of the chest cannot be enlarged by any treatment.[medicalsubstance.com]

Prognosis

  • A small proportion of cases are associated with structural rearrangements involving 17q and it has been proposed that this subgroup have a milder phenotype and better prognosis compared to those with mutations in the SOX9 gene.[ncbi.nlm.nih.gov]
  • Prognosis Newborns suffering from campomelic dysplasia often die soon after birth as a result of respiratory insufficiency, but 5 to 10 % of individuals survive.[orpha.net]

Etiology

  • Etiology has not been determined although evidence suggests genetic heterogeneity in patients with campomelia. Cytogenetic analysis in the past have revealed an unexpectedly high incidence of a 46, XY karyotype in phenotypic females.[ncbi.nlm.nih.gov]
  • Etiology The syndrome is associated with anomalies in the SOX9 gene (localized to 17q24), either as a result of chromosomal recombination involving this locus or due to heterozygous de novo mutation of this gene.[orpha.net]
  • Etiology Campomelic dysplasia is an autosomal dominant defect in the SOX-9 gene, located on chromosome 17. This defect results in haploinsufficiency of SOX-9 Dec 21, 2015 Posted by in PEDIATRIC IMAGING Comments Off on 123 Campomelic Dysplasia[radiologykey.com]

Epidemiology

  • Summary Epidemiology Prevalence at birth is approximately 1/300 000. Clinical description A few cases of a variant syndrome, referred to as acampomelic campomelic dysplasia'' have been described.[orpha.net]
  • […] period, CMD patients have shortened life spans due to lifelong respiratory issues.Those patients with ambiguous genitalia or sex reversal at birth, of course, maintain that state, and are either sterile or have reduced fertility. [ citation needed ] Epidemiology[en.wikipedia.org]

Prevention

  • With improving treatment of respiratory insufficiency, the survival rate of affected infants has increased, thereby necessitating treatment of the musculoskeletal malformations to prevent additional morbidity.[ncbi.nlm.nih.gov]

  • These mutations prevent the production of the SOX9 protein or result in a protein with impaired function.[ghr.nlm.nih.gov]
  • The method is safe and effective in children as it prevents the lungs from collapsing. Complex cardiac abnormalities may need special care for an indefinite amount of time.[primehealthchannel.com]
  • This might include prevention of choking while eating via a tube that connects the nose to the stomach for feeding (nasogastric tube), prevention of inhaling food on accident (lung aspiration), or physiotherapy and/or surgery to correct bone malformations[rarediseases.org]
