-
- Cerebro-Costo-Mandibular Syndrome is a rare genetic disorder
- characterized by an unusually small jaw (micrognathia), abnormalities of the
- palate and multiple rib defects. Sometimes mild to moderate mental
- retardation may occur as a result of respiratory distress during infancy.
-
- Symptoms
-
- Cerebro-Costo-Mandibular Syndrome is characterized by an abnormally small jaw
- (micrognathia), downward displacement or retraction of the tongue
- (glossoptosis), abnormalities of the palate usually manifested as a cleft
- soft palate, and multiple rib defects particularly in the 4th and 5th pairs.
- Sometimes mild to moderate mental deficiency may occur which can be caused by
- respiratory distress during infancy. Numerous associated features involving
- the bones, kidneys, heart, windpipe (trachea), and hearing have also been
- reported in the medical literature.
-
- Increased susceptibility to respiratory infections may be life
- threatening in some cases. Establishing adequate nipple feeding is often
- difficult and may lead to failure to thrive. Rare cases of hearing loss due
- to a defect of the middle ear with delayed speech development can be
- associated with this disorder. Recurrent pneumonia and middle ear infection
- (otitis media) often occur. Rib fractures and rib gap defects
- (pseudoarthosis) usually tend to improve with age.
-
- Causes
-
- Cerebrocostomandibular Syndrome is a genetic disorder transmitted through
- autosomal recessive inheritance. Manifestations of the disorder may not be
- present in all who inherit the disease (variable penetrance). Respiratory
- distress immediately after birth should be guarded against. (Human traits
- including the classic genetic diseases, are the product of the interaction of
- two genes for that condition, one received from the father and one from the
- mother. In recessive disorders, the condition does not appear unless a
- person inherits the same defective gene from each parent. If one receives
- one normal gene and one gene for the disease, the person will be a carrier
- for the disease, but usually will show no symptoms. The risk of transmitting
- the disease to the children of a couple, both of whom are carriers for a
- recessive disorder, is twenty-five percent. Fifty percent of their children
- will be carriers, but healthy as described above. Twenty-five percent of
- their children will receive both normal genes, one from each parent and will
- be genetically normal.) Variable penetrance means that characteristics or
- symptoms of a particular disorder may not be manifested in all those who
- inherit the defective genes.)
-
- Affected Population
-
- Cerebro-Costo-Mandibular Syndrome is a very rare disorder present at birth.
- Persons of European descent are primarily affected. Males and females tend
- to be affected in equal numbers.
-
- Related Disorders:
-
- The following conditions may be similar to symptoms of Cerebro-Costo-
- Mandibular Syndrome. Comparisons may be useful for a differential diagnosis:
-
- Micrognathia is characterized by an unusually small jaw.
-
- Pierre Robin Syndrome (Pierre Robin Anomaly; Robin Syndrome; Cleft
- Palate, Micrognathia and Glossoptosis; Micrognathia and Glossoptosis
- Syndrome). This syndrome is part of Cerebro-Costo-Mandibular Syndrome. This
- syndrome is characterized by an abnormally small jaw (micrognathia), downward
- displacement of the tongue, and a cleft palate. It is a genetic disorder
- probably inherited through autosomal recessive genes. (For more information
- on this disorder, choose "Pierre Robin" as your search term in the Rare
- Disease Database.)
-
- Therapies: Standard
-
- Intensive medical care for respiratory distress, feeding difficulty and
- respiratory infections is necessary for infants with Cerebro-Costo-Mandibular
- Syndrome. The palate can be surgically repaired. Genetic counseling is
- recommended for families of children with this disorder.
-
- Therapies: Investigational
