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]

• Disability

  It is unclear how these alterations cause the shortening of the long bones, or intellectual disability and other characteristics of the RCDP3. [ivami.com]

  This disease is characterized by congenital cataracts, proximal limb shortening, seizures, growth delay and intellectual disability. Due to respiratory complications, this condition is usually fatal within the first decade of life. [sema4genomics.com]

• Poor Feeding

  After ten days, the baby was seen by the primary-care physician (PCP) for a new-onset fever and poor feeding. The patient was put on amoxicillin for otitis media but no clinical improvement ensued. [file.scirp.org]

  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]

• Skin Lesion

  The skin lesions typically present at birth and often persist, but can develop at any age, often at a site of skin damage. [ncbi.nlm.nih.gov]

  The clinical picturemay range from mild disease to an extremely severe condition,with cataracts, asymmetrical shortening of long bones, scoliosis,ichthyotic-type skin lesions, and flattened facies with broadnasal bridge (6). [rb.org.br]

• Dry Skin

  Once a child has been diagnosed with RCDP a skin sample is taken to determine which type of RCDP a child has (see below). An RCDP infant will often, but not always, be born with cataracts in both eyes. They might suffer stiff joints and dry skin. [geneticdisordersuk.org]
