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.

Most children with the classic form of RCDP1 do not live beyond the age of 10, and some will die in infancy. The main features of the disease are shortening of the proximal long bones, punctate calcifications located in the epiphyses of long bones condrodispplasia in soft tissues around joints and vertebral column, vertebral clefting, dysmorphic face, and severe growth retardation, whereas cervical spinal stenosis may also rarely be present.

Moreover, as in Zellweger syndrome, the plasma phytanic acid concentrations were found to be elevated. He suggested that this represents a distinct form of chondrodysplasia punctata which might be called the humerometacarpal HM type.
