Colobomatous microphthalmia-rhizomelic dysplasia syndrome is a rare, genetic developmental defect during embryogenesis characterized by a range of developmental eye anomalies (including anophthalmia, microphthalmia, colobomas, microcornea, corectopia, cataract) and symmetric limb rhizomelia with short stature and contractures of large joints. Intellectual disability with autistic features, macrocephaly, dysmorphic features, urogenital anomalies (hypospadia, cryptorchidism), cutaneous syndactyly and precocious puberty may also be present. |

Cleidorhizomelic syndrome is a rhizo-mesomelic dysplasia characterized by rhizomelic short stature/dwarfism in combination with lateral clavicular defects. Additional manifestations include brachydactyly with bilateral clinodactyly and hypoplastic middle phalanx of the fifth digit. X-ray demonstrated an apparent Y-shaped or bifid distal clavicle. Cleidorhizomelic syndrome has been reported in one family (mother and son) and is suspected to be transmitted in an autosomal dominant manner. There have been no further descriptions in the literature since 1988. |

Main skeletal abnormalities comprise short stature, narrow chest, scoliosis, mesomelic limb shortening, and brachydactyly. Radiographic features include severe metaphyseal irregularities of the tubular bones, platyspondyly with coronal clefts, cone-shaped epiphyses of the hands, square iliac wings, and coxa valga. Additional extraskeletal manifestations like pulmonary hypoplasia, cystic renal disease, and non-obstructive hydrocephalus have also been reported. |

Axial spondylometaphyseal dysplasia is a rare type of spondylometaphyseal dysplasia characterized by metaphyseal changes of the truncal-juxta truncal bones associated with retinal dystrophy. Patients typically present progressive postnatal growth failure with rhizomelic shortening of the limbs, a deformed, hypoplastic thorax and retinitis pigmentosa or pigmentary retinal degeneration. Radiographic findings include short ribs with flared, cupped anterior ends, mild platyspondyly, lacy ilia and metaphyseal dysplasia of the proximal femora. |

Multiple epiphyseal dysplasia, Lowry type is a rare primary bone dysplasia characterized by small, flat epiphyses (especially the capital femoral epiphyses), rhizomelic shortening of limbs, cleft of secondary palate, micrognathia, mild joint contractures and facial dysmorphism (including mildly upward-slanting palpebral fissures, hypertelorism, broad nasal tip). Additionally reported features include scoliosis, genu valgum, mild pectus excavatum, platyspondyly, dislocated radial heads, brachydactyly, hypoplastic fibulae and talipes equinovarus. |

Spondyloepimetaphyseal dysplasia-hypotrichosis syndrome is a rare primary bone dysplasia disorder characterized by congenital hypotrichosis associated with rhizomelic short stature (more pronounced in upper limbs than lower limbs), limited hip abduction and mild genu varum. Flared and irregular metaphyses, delayed and irregular epiphyseal ossification and pear-shaped vertebral bodies are characteristic radiologic findings. |

Omodysplasia is a rare skeletal dysplasia characterized by severe limb shortening and facial dysmorphism. Two types of omodysplasia have been described: an autosomal recessive or generalized form (also referred to as micromelic dysplasia with dislocation of radius) marked by severe micromelic dwarfism with predominantly rhizomelic shortening of both the upper and lower limbs, and an autosomal dominant form in which stature is normal and shortening is limited to the upper limbs. |

Rhizomelic dysplasia, Patterson-Lowry type is a rare primary bone dysplasia characterized by short stature, severe rhizomelic shortening of the upper limbs associated with specific malformations of humeri (including marked widening and flattening of proximal metaphyses, medial flattening of the proximal epiphyses, and lateral bowing with medial cortical thickening of the proximal diaphyses), marked coxa vara with dysplastic femoral heads and brachymetacarpalia. |

Smith-McCort dysplasia (SMC) is a rare spondyloepimetaphyseal dysplasia characterized by the clinical manifestations of coarse facies, short neck, short trunk dwarfism with barrel-shaped chest and rhizomelic limb shortening, as well as specific radiological features (i.e. generalized platyspondyly with double-humped vertebral end plates and iliac crests with a lace-like appearance) and normal intelligence. The clinical and skeletal features are similar to those seen in the allelic disorder Dyggve-Melchior-Clausen syndrome but can be distinguished from this syndrome by the absence of intellectual deficiency and microcephaly in SMC. |
