Presentation
In accordance with two previous case reports, the present findings suggest that a campomelic dysplasia variant without campomelia may exist. [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]
Respiratoric
- 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]

Treatment
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]
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 discussed earlier, Campomelic dysplasia is a highly fatal disorder that does not have any standard treatment. Emergency life support measures can only prolong the life of the affected patient. [primehealthchannel.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]
The diagnosis is usually difficult because of its rare presentation and the prognosis is poor. [journals.lww.com]
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 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]
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]
[…] unremakable ultrastructure: more numerous dark cells surrounded by granular and flocculent materials physeal growth zones: almost normal +/- mild retardation disorganization with osteoporosis no defect in bone collagen, ground substance or mineralization Etiology [humpath.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]
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]
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]
These mutations can prevent your child’s bones from growing normally. While skeletal dysplasia runs in families, you can potentially pass the condition to your child even if you don’t have a known family history of it. [healthline.com]
