• Disproportionate Short Stature

  Rhizomelic chondrodysplasia punctata (RCDP) is a peroxisomal disorder characterized by disproportionately short stature primarily affecting the proximal parts of the extremities, a typical facial appearance including a broad nasal bridge, epicanthus, [ncbi.nlm.nih.gov]

  Rhizomelic chondrodysplasia punctata (RCDP) is an autosomal recessive peroxisomal disorder characterized by disproportionate short stature with rhizomelic limb shortening, congenital cataracts, distinct facial features, severe intellectual disability, [ctgt.net]

  Note disproportionately short stature with mesomelic shortening and deformities of forearms and legs (in mesomelic dysplasia) and short forearms with Madelung-type deformity (in Leri-Weill syndrome). [emedicine.medscape.com]

• Poor Growth

  People with RCDP have very poor growth and often develop joint deformities ( contractures ) that make the joints stiff and painful. [rarediseases.info.nih.gov]

  Painful joint contractures, poor growth, cataracts developing in infancy, hearing loss, and seizures also occur frequently. [secure.ssa.gov]

  Babies with RCP usually have shortening of the upper arms and legs, joint contractures (stiff joints), poor growth, cataracts, dry skin and severe developmental delays. [angelfire.com]

  One child, presenting with developmental delay and poor growth, subsequently developed retinitis pigmentosa and peripheral neuropathy, features overlapping those of adult Refsum disease [ Braverman et al 2002 ]. [ncbi.nlm.nih.gov]

• Rigor

  Throughout, the approach of OTM is humane and ethical and, at the same time, factual, reliable, honest(especially where knowledge is limited) and rigorously scientific. This is not just a textbook of "First World" medicine. [books.google.com]

• Aspiration

  Recurrent respiratory tract infections are common due to neurological causes, aspiration, immobility, and a small chest with limited excursion. [physio-pedia.com]

  Respiratory infections such aspneumonia, and aspiration (inhaling liquids or solids into the lungs) may affect sufferers. Some children have heart defects. Cataracts can be removed in infancy through surgery. [geneticdisordersuk.org]

  Pneumonias and upper respiratory infections are most frequent, while aspirations are also fairly common. Temperature: Infants with RCP often seem to perspire easily and may overheat. [angelfire.com]

  Most children with RCDP1 have recurrent respiratory tract infections caused by neurologic compromise, aspiration, immobility, and a small chest with restricted expansion. [ncbi.nlm.nih.gov]

• Failure to Thrive

  The patient was admitted to the hospital at 11 months of age with a phenotype similar to that of her brother who had died at 2 years of age: short proximal arms, bilateral cataracts, developmental delay, failure to thrive, gastroesophageal efflux, microcephaly [gepedia.com]

  […] sepsis • Weight at death 2.5 kg (Failure to thrive) 6. Second Child • Antenatal history - ? Polyhydramnios • Term born/3.5kgs/Respiratory distress at birth Nicu stay x 20 days. [slideshare.net]

  All affected infants have severe failure to thrive, mental retardation, joint contractures, and cataracts. [mhmedical.com]

  Many infants are additionally diagnosed with "failure to thrive" (small size due to inadequate nutritional intake) but their small size is simply part of the disorder. [angelfire.com]

  Affected infants may fail to grow and gain weight at the rate expected for age and gender (failure to thrive). Growth deficiencies may ultimately result in a final adult height that is below normal (short stature). [rarediseases.org]

• High Arched Palate

  Rhizomelic chondrodysplasia punctata (RCDP) is a peroxisomal disorder characterized by disproportionately short stature primarily affecting the proximal parts of the extremities, a typical facial appearance including a broad nasal bridge, epicanthus, high-arched [ncbi.nlm.nih.gov]

• Joint Deformity

  People with RCDP have very poor growth and often develop joint deformities ( contractures ) that make the joints stiff and painful. [rarediseases.info.nih.gov]

  People with chondrodysplasia punctata Rhizomelic often develop joint deformities or contractures, leading to stiff and painful joints. [ivami.com]

  Short stature Shortening of upper arms and thighs Joint deformities Distinct facial features Clouding of the lens of the eye (cataracts) Delayed intellectual development Respiratory issues *Please be aware, not all of the characteristics may be present [littlepeopleuk.org]

  People with rhizomelic chondrodysplasia punctata often develop joint deformities (contractures) that make the joints stiff and painful. Distinctive facial features are also seen with rhizomelic chondrodysplasia punctata. [ghr.nlm.nih.gov]

• Arthralgia

  Similar symptoms have been observed in patients with hypergammaglobulinemia type D and periodic fever syndrome in addition to skin rash and arthralgias. [emedicine.medscape.com]

• Prominent Cheeks

  In reference to the distinctive facial features include: prominent forehead, hypertelorism, midface hypoplasia, a small nose pointing upwards and prominent cheeks. [ivami.com]

  Siblings: Meeting the needs of all your children, while not neglecting your own, is one of the challenges facing parents of children with RCP. It is also one of the world's greatest balancing acts. [angelfire.com]

• Learning Difficulties

  RCDP sufferers have severe learning difficulties. The condition can be life-limiting at an early age. RCDP is classed as ‘peroxisomal’ disorder. [geneticdisordersuk.org]

TREATMENT There is no current cure for RCDP. Treatment is supportive and many include physical therapy, anti-seizure medication, hearing amplification, and cataract removal. [secure.ssa.gov]

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]

Treatment is symptomatic and may include physiotherapy and orthopedic procedures, eye surgery, and nutritional plans. For example, RCDP1 patients may need diet restriction of phytanic acid. [2] [3] Last updated: 7/7/2017 [rarediseases.info.nih.gov]

This is how doctors determine the prognosis for the child - a blood test for plasmalogens. The higher the plasmalogen levels the better the outcome for the child. [geneticdisordersuk.org]

Treatment and prognosis While prognosis is variable, the rhizomelic forms can be lethal 3. [radiopaedia.org]

Prognosis Rhizomelic chondrodysplasia has a severe prognosis with death generally occurring during the first decade of life, mainly due to respiratory complications. [orpha.net]

If a correct diagnosis is established, it has a direct impact on prognosis, in addition to a proper treatment and genetic counseling to parents 17. [scielo.conicyt.cl]

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]
