Presentation
In conclusion, the clinical presentation and peroxisome profile of the patient suggest that this novel mutation leads to RCDP type 1. [ncbi.nlm.nih.gov]
Instead, 2 novel alleles are described, including 64_65delGC, which was present on a single PEX7 haplotype and could represent a common allele in the Indian population. [jhu.pure.elsevier.com]
Life expectancy is considerably reduced. [1] [2] Prevalence Estimated 1 in 100,000; RCDP 1 is most common subtype. [1] Characteristics/Clinical Presentation These patients present with severe and symmetrical shortening of the proximal long bones (rhizomelia [physio-pedia.com]

Prevention of Secondary Complications Poor feeding and recurrent aspiration necessitate the placement of a gastrostomy tube. Note: Improved nutrition does not enhance linear growth. [ncbi.nlm.nih.gov]

Ten days before internment the patient had begun to present with coughing and episodes of cyanosis and choking after suckling, being assessed by a cardiologist who observed rough a and intense systolic heart murmur and. suspecting interventricular communication [jped.com.br]
Treatment
TREATMENT Treatment for Rhizomelic Chondrodysplasia Punctata Type 1 is symptomatic depending on the features of an individual. [evolvegene.com]
Treatment Treatment Options: No treatment is available beyond supportive measures. Cataract removal may improve vision but the poor prognosis for longevity requires caution be used. [disorders.eyes.arizona.edu]

Contact other families affected by rhizomelic chondrodysplasia punctata Treatments There is no cure for RCDP however research is being carried out in the United States into potential treatments. [geneticdisordersuk.org]
Management and treatment There is no specific treatment for the enzyme defect. Prognosis Rhizomelic chondrodysplasia has a severe prognosis with death generally occurring during the first decade of life, mainly due to respiratory complications. [orpha.net]
Prognosis
What is the prognosis for a person with Rhizomelic Chondrodysplasia Punctata Type 1? The prognosis for a child with the classic form of RCDP1 is poor. Many die in the first or second year of life, and few survive beyond the age of 10. [counsyl.com]

Treatment and prognosis While prognosis is variable, the rhizomelic forms can be lethal 3. [radiopaedia.org]
The rhizomelic condrodisplasia has a grave prognosis, usually with death during first decade of life (mainly because of respiratory complications). [tellmegen.com]

Etiology
Etiology The disease is caused by defective peroxisome metabolism. [orpha.net]
These findings, in combination with the specific clinical presentation, leads to the diagnosis of rhizomelic chondrodysplasia punctata. [3] Etiology/Causes Genetic mutations of three genes mentioned above, which leads to peroxisome biogenesis disorders [physio-pedia.com]
