Is RCDP genetic?
Background. RCDP is an ultra-rare pediatric genetic disorder with an estimated prevalence of 1 in 100,000. The disease results from a plasmalogen lipid deficiency caused by mutations in genes involved in plasmalogen biosynthesis.
Is Chondrodysplasia Punctata dominant or recessive?
autosomal dominant type (autosomal dominant) Rhizomelic chondrodysplasia punctata, usually lethal by 2 years of age, is a rare autosomal recessive disorder of peroxisome metabolism.
Can kids with RCDP talk?
She can walk, talk and play, despite misshapen bones, painful muscles and joints and deteriorating vision. In comparison, most children with RCDP never learn to sit, walk, talk or feed themselves.

How common is chondrodysplasia?
Blomstrand lethal chondrodysplasia (BLC) is a rare disorder characterized by short-limbed dwarfism with craniofacial malformations, hydrops, hypoplastic lungs, and aortic coarctation. It is classified as severe (type I) and mild (type II) forms.
What is Rhizomelic limb shortening?
Rhizomelic short stature refers to skeletal dysplasias where the main shortening is due to involvement of the proximal limb segments i.e. femora and humeri. Typical examples of Rhizomelic short stature are achondroplasia and pseudoachondroplasia.
