In these cases, the affected person usually inherits one mutated copy of the gene from each parent, both of whom are likely unaffected. In a person with an autosomal dominant condition, having only one mutated copy of the responsible gene in each cell is enough to cause signs or symptoms of the condition. An autosomal dominant condition may be inherited from an affected parent, or the mutation may occur for the first time in the affected person. Affected people from families suggesting autosomal recessive or autosomal dominant inheritance have overlapping features. In both groups, the severity varies, both among affected members of the same family and between families. The different patterns of inheritance seen support the likelihood that there is more than one genetic cause of CCMS.

Abdalla is Clinical Instructor of Radiology, Dr. Panigrahy is Associate Professor of Radiology, and Dr. Abstract Cerebro-costo-mandibular syndrome CCMS is a rare syndrome that includes a constellation of mandibular hypoplasia and posterior rib defects as its basic features.
Additional features can include hearing loss, tracheal cartilage abnormalities, scoliosis, elbow hypoplasia, and spina bifida. Here we report two cases of CCMS and discuss the reported long-term outcome of the disease. It is a rare syndrome; only about 60 cases have been previously reported. The basic features of CCMS are mandibular hypoplasia and gap defects of many ribs that may simulate rib fractures. In Pierre Robin sequence, the main pathology is mandibular hypoplasia that, during intrauterine life, leads to inability of the tongue to migrate caudally, resulting in abnormal positioning of the tongue and hindrance to the normal development of the palate.
Because its results are due to a single abnormality, Pierre Robin is considered a sequence rather than a syndrome. Here we report two cases of CCMS. The first case is a neonate, and the second case is year-old patient who was followed up in our institution. Case 1 A full-term male baby had respiratory distress on day 1 of his life. A chest x-ray was obtained because of respiratory difficulties Fig.
