Sclerosis of the skull may lead to asymmetry of the mandible, as well as to cranial nerve compression, that may finally result in hearing loss and facial palsy (summary by Nurnberg et al., 1997).&#13; The delineation of separate autosomal dominant (CMDD; 123000) and autosomal recessive forms of CMD by Gorlin et al. (1969) was confirmed by reports that made it evident that the dominant form is relatively mild and comparatively common, whereas the recessive form is rare, severe, and possibly heterogeneous." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln">Craniometaphyseal dysplasia is an osteochondrodysplasia characterized by hyperostosis and sclerosis of the craniofacial bones associated with abnormal modeling of the metaphyses. Sclerosis of the skull may lead to asymmetry of the mandible, as well as to cranial nerve compression, that may finally result in hearing loss and facial palsy (summary by Nurnberg et al., 1997).&#13; The delineation of separate autosomal dominant (CMDD; 123000) and autosomal recessive forms of CMD by Gorlin et al. (1969) was confirmed by reports that made it evident that the dominant form is relatively mild and comparatively common, whereas the recessive form is rare, severe, and possibly heterogeneous. [from <a title="Online Mendelian Inheritance in Man" href="http://www.omim.org" class="defSource" target="_blank">OMIM</a>]</div>

<div class="portlet_content ln"><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />There are two types of craniometaphyseal dysplasia, which are distinguished by their pattern of inheritance and genetic cause. They are known as the autosomal dominant and autosomal recessive types.<br /><br />The x-rays of individuals with craniometaphyseal dysplasia show unusually shaped long bones, particularly long bones in the legs. The ends of these bones are wider and appear less dense than usual in people with this condition.<br /><br />Bone overgrowth in the head causes many of the signs and symptoms of craniometaphyseal dysplasia. Affected individuals typically have distinctive facial features such as a wide nasal bridge, a prominent forehead, wide-set eyes (hypertelorism), and a prominent jaw. Excess bone formation in the jaw can delay teething (dentition) or result in absent (non-erupting) teeth. Infants with craniometaphyseal dysplasia may have breathing or feeding problems caused by narrow nasal passages. In severe cases, abnormal bone growth can pinch (compress) the nerves that extend from the brain to various areas of the head and neck (cranial nerves). Compression of the cranial nerves can lead to paralyzed facial muscles (facial nerve palsy), blindness, or deafness.<br /><br />Craniometaphyseal dysplasia is a rare condition characterized by thickening (overgrowth) of bones in the skull (cranium) and abnormalities in a region at the end of long bones known as the metaphysis. The abnormal bone growth continues throughout life. Except in the most severe cases, the lifespan of people with craniometaphyseal dysplasia is normal.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/craniometaphyseal-dysplasia">https://medlineplus.gov/genetics/condition/craniometaphyseal-dysplasia</a></div></div>
