Congenital central hypoventilation

Congenital central hypoventilation syndrome (CCHS) is a rare disorder of respiratory and autonomic regulation. It is typically characterized by a classic presentation in newborns and, rarely, a milder later-onset (LO-CCHS) presentation in toddlers, children, and adults. Classic CCHS presents in newborns as: Apparent hypoventilation with monotonous respiratory rates and shallow breathing either during sleep only or while awake as well as asleep; Autonomic nervous system dysregulation (ANSD); and In some individuals, altered development of neural crest-derived structures (i.e., Hirschsprung disease) and/or tumors of neural crest origin (neuroblastoma, ganglioneuroma, and ganglioneuroblastoma). Individuals with CCHS who have been diagnosed as newborns and ventilated conservatively and consistently throughout childhood have now reached the age of 20 to 30 years; they are highly functional and live independently. LO-CCHS manifests as nocturnal alveolar hypoventilation and mild ANSD. Individuals with LO-CCHS who were not identified until age 20 years or older have now reached the age of 30 to 55 years. [from GeneReviews]

SUDDEN INFANT DEATH SYNDROME

Sudden infant death syndrome (SIDS) is a diagnosis of exclusion which should be made only after a thorough autopsy without identification of a specific cause of death (Mage and Donner, 2004). Weese-Mayer et al. (2007) provided a detailed review of genetic factors that have been implicated in SIDS. The authors concluded that SIDS represents more than 1 entity and has a heterogeneous etiology most likely involving several different genetically controlled metabolic pathways. [from OMIM]

Neonatal hemochromatosis

Neonatal hemochromatosis (NH) is characterized by hepatic failure in the newborn period and heavy iron staining in the liver. In addition, there is marked siderosis of extrahepatic tissues, including the heart and pancreas (Driscoll et al., 1988). Whitington (2007) postulated that some cases of neonatal hemochromatosis result from maternal alloimmunity directed at the fetal liver, and therefore do not represent an inherited mendelian disorder. Other causes may result from metabolic disease or perinatal infection. In particular, he commented that the disorder is not related to the family of inherited liver diseases that fall under the classification of hereditary hemochromatosis (see, e.g., 235200). Whitington (2007) proposed the term 'congenital alloimmune hepatitis.' In the past, the disorder has loosely been labeled 'neonatal hepatitis' and 'giant cell hepatitis,' which are pathologic findings in the liver representing a common response to a variety of insults, including cholestatic disorders and infection, among others (Fawaz et al., 1975; Knisely et al., 1987; Kelly et al., 2001). [from OMIM]
