Description : Congenital diaphragmatic hernia (CDH) refers to a group of congenital defects in the structural integrity of the diaphragm which are often associated with lethal pulmonary hypoplasia and pulmonary hypertension. Prevalence in newborns ranges from 1 in 2,500 to 1 in 4,000, and there is a 30 to 60% mortality rate (Langham et al., 1996; Harrison et al., 1994; Nobuhara et al., 1996). Most cases of congenital diaphragmatic hernia are sporadic. - Genetic Heterogeneity of Diaphragmatic Hernia One form of congenital diaphragmatic hernia, DIH1, has been mapped to chromosome 15q26, and another, DIH2 (222400), to chromosome 8p23.1. See also DIH3 (610187), which is associated with mutation in the ZFPM2 gene (603693). There is evidence for further genetic heterogeneity. Also see 306950 for a possible X-linked form. Congenital diaphragmatic hernia can also present with other congenital anomalies. Fryns syndrome (229850) may be the most common autosomal recessive syndrome with DIH as a cardinal feature (Slavotinek et al., 2005). See Holder et al. (2007) for a review of genetic factors in congenital diaphragmatic hernia. Pober (2008) reviewed genetic aspects of congenital diaphragmatic hernia, with emphasis on various syndromes in which CDH occurs along with other manifestations.;
