A rare primary bone dysplasia characterized by costovertebral ossification defects with small chest, abnormal vertebral segmentation, and posterior rib gaps containing incompletely differentiated mesenchymal tissue. Consistent dysmorphic craniofacial features include ocular hypertelorism, epicanthal folds, depressed nasal bridge with short nose, and low-set ears. The most common extraosseous manifestations are renal abnormalities such as multicystic kidneys. The disease is usually perinatally lethal due to respiratory insufficiency. |

A rare genetic disease characterized by global developmental delay with language and cognition deficiencies, behavioral problems, osteopenia, joint laxity, skin defects consisting of hyperkeratosis and sweat gland and melanocyte abnormalities with hypopigmented areas, and abnormal hair structure. Mild facial dysmorphism (prominent forehead, thick eyebrows, epicanthal folds, broad nasal bridge, long philtrum, and micrognathia), abnormalities of the teeth, and skeletal and cardiac anomalies have also been described. |

A rare systemic disease characterized by the association of the features of Ehlers-Danlos syndrome with those of osteogenesis imperfecta. Predominant clinical manifestations include generalized joint hypermobility and dislocations, skin hyperextensibility and/or translucency, easy bruising, and invariable association with mild signs of osteogenesis imperfecta, including short stature, blue sclera, and osteopenia or fractures. |

Spondylometaphyseal dysplasia-cone-rod dystrophy syndrome is characterized by the association of spondylometaphyseal dysplasia (marked by platyspondyly, shortening of the tubular bones and progressive metaphyseal irregularity and cupping), with postnatal growth retardation and progressive visual impairment due to cone-rod dystrophy. So far, it has been described in eight individuals. Transmission appears to be autosomal recessive. |

A rare, hereditary connective tissue disease characterized by severe ocular manifestations due to extreme corneal thinning and fragility with rupture in the absence of significant trauma, often leading to irreversible blindness. Extraocular manifestations comprise deafness, developmental hip dysplasia, and joint hypermobility. |

A rare primary bone dysplasia characterized by the association of spondylometaphyseal dysplasia, generalized joint laxity, and dentinogenesis imperfecta. 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. |

A rare multiple congenital anomalies/dysmorphic syndrome characterized by severe global developmental delay, osteogenesis imperfecta, presence of wormian bones, seizures, ocular abnormalities (blue sclerae, optic atrophy, retinal detachment), and dysmorphic facial features (including frontal bossing, low anterior hairline, medial flare of the eyebrows, long eyelashes, hypertelorism, depressed nasal bridge, and low-set, large ears). There have been no further descriptions in the literature since 1994. |

A rare dysostosis syndrome characterized by abnormal fusion of the spleen with the gonad (or more rarely with remnants of the mesonephros), limb abnormalities (consisting of amelia or severe reduction defects leading to upper and/or lower rudimentary limbs) and orofacial abnormalities such as cleft palate, bifid uvula, microglossia and mandibular hypoplasia. It could also be associated with other malformations such as cryptorchidism, anal stenosis/atresia, hypoplastic lungs and cardiac malformations. |

A rare genetic disease characterized by congenital oculocutaneous hypopigmentation, visual impairment, generalized osteoporosis with skeletal anomalies such as short stature, short neck and trunk, kyphosis, scoliosis, and platyspondyly, and dysmorphic facial features (including long philtrum, small mouth, micrognathia, and prominent ears). Moderate joint hyperelasticity and muscular hypotrophy have also been reported. |

A rare, genetic, syndromic intellectual disability disorder characterized by non-progressive, congenital, marked, central hypotonia, severe psychomotor delay and intellectual disability, chronic constipation, distended abdomen, abnormal dermatoglyphics, delayed and dysharmonic skeletal maturation, and preponderance of type 2 larger-sized muscle fibers. Additional features include narrow and high-arched palate, prominent nasal root, long philtrum, and open mouth with drooling, as well as variably present cryptorchidism, hypertelorism, and tapered fingers. Seizures and/or an abnormal electroencephalograph may also be associated. There have been no further descriptions in the literature since 1994. |
