A rare skeletal disorder characterized clinically by multiple fractures, wormian bones of the skull, dentinogenesis imperfecta and facial dysmorphism (hypertelorism, periorbital fullness). Although the signs are very similar to osteogenesis imperfecta, characteristic cortical defects in the absence of osteopenia and collagen abnormalities are considered to be distinctive. There have been no further descriptions in the literature since 1999. |

Metaphyseal dysostosis-intellectual disability-conductive deafness syndrome is characterized by metaphyseal dysplasia, short-limb dwarfism, mild intellectual deficit and conductive hearing loss, associated with repeated episodes of otitis media in childhood. It has been described in three brothers born to consanguineous Sicilian parents. Variable manifestations included hyperopia and strabismus. The mode of inheritance is autosomal recessive. |

Mononen-Karnes-Senac syndrome is characterized by skeletal dysplasia associated with finger malformations (brachydactyly with short and abducted thumbs, short index fingers, and markedly short and abducted great toes), variable mild short stature, and mild bowleg with overgrowth of the fibula. It has been described in two males, their mothers, and a maternal aunt. Females are less severely affected than males. X-linked dominant inheritance is suggested. |

A rare autosomal dominant heart-hand syndrome that is characterized by bisymmetric brachydactyly accompanied by long thumbs, joint anomalies (restriction of motion at the shoulder and metacarpophalangeal joints) and cardiac conduction defects. Additional features include small hands and feet, clinodactyly, narrow shoulders with short clavicles, pectus excavatum and mild shortness of the limbs, cardiomegaly and murmur of pulmonic stenosis. There have been no new reports since 1981. |

A rare X-linked syndromic intellectual disability characterized by intellectual deficit, choroideremia, horizontal nystagmus, severe myopia, acrokeratosis verruciformis-like skin abnormality, anhidrosis, and scapular winging. There have been no further descriptions in the literature since 1959. |
