Presentation
We present two cases of CRCP type I with two different forms of presentation, one severe and another one mild or bening, in relation with the residual enzyme activity and we revise the main clinical aspects(AU) [pesquisa.bvsalud.org]
Infants who survivebeyond the first year usually present normal life expectancy andmental development. [rb.org.br]
Clinical Characteristics Ocular Features: Congenital cataracts are the outstanding ocular feature of this syndrome and are present in over 70% of patients. [disorders.eyes.arizona.edu]
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]

Treatment
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]
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]
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]
