CONDRODISPLASIA PUNCTATA RIZOMLICA PDF

Rhizomelic chondrodysplasia punctata is a rare developmental brain disorder characterized by systemic shortening of the proximal bones (i.e. rhizomelia). A number sign (#) is used with this entry because of evidence that rhizomelic chondrodysplasia punctata type 1 (RCDP1) is caused by homozygous or. Rhizomelic chondrodysplasia punctata (RCDP) is a peroxisomal disorder characterized by disproportionately short stature primarily affecting the proximal parts.
