chondrodysplasia [kon″dro-dis-pla´zhah] enchondromatosis.chondrodysplasia puncta´ta a heterogeneous group of bone dysplasias, the common characteristic of which is stippling of the epiphyses in infancy. The group includes a severe autosomal recessive form (rhizomelic dwarfism), an autosomal dominant form (Conradi-Hünermann syndrome), and a milder X-linked form.chon·dro·dys·pla·si·a punc·ta·'ta [MIM*215105] a developmental disorder characterized by epiphysial stippling, coronal clefting of the vertebrae, dwarfism with rhizomelic shortening of the limbs, joint contractures, congenital cataracts, ichthyosis, and mental retardation. Autosomal dominant and recessive and X-linked forms exist. Synonym(s): dysplasia epiphysialis punctata, hypoplastic fetal chondrodystrophy, stippled epiphysischondrodysplasia punctata A clinically and genetically heterogeneous group of conditions characterised by skeletal defects and stippled epiphyses.
