Molecular analysis of congenital central hypoventilation syndrome.

Congenital central hypoventilation syndrome (CCHS or Ondine's curse; OMIM 209880) is a disorder characterized by an idiopathic failure of the automatic control of breathing. CCHS is frequently complicated with neurocristopathies such as Hirschsprung's disease (HSCR). The genes involved in the RET-GDNF signaling and/or EDN3-EDNRB signaling pathways have been analyzed as candidates for CCHS; however, only a few patients have mutations of the RET, EDN3, and GDNF genes. Recently, mutations of the PHOX2B gene, especially polyalanine expansions, have been detected in two thirds of patients. We studied the RET, GDNF, GFRA1, PHOX2A, PHOX2B, HASH-1, EDN1, EDN3, EDNRB, and BDNF genes in seven patients with isolated CCHS and three patients with HSCR. We detected polyalanine expansions and a novel frameshift mutation of the PHOX2B gene in four patients and one patient, respectively. We also found several mutations of the RET, GFRA1, PHOX2A, and HASH-1 genes in patients with or without mutations of the PHOX2B gene. Our study confirmed the prominent role of mutations in the PHOX2B gene in the pathogenesis of CCHS. Mutations of the RET, GFRA1, PHOX2A, and HASH-1 genes may also be involved in the pathogenesis of CCHS. To make clear the pathogenesis of CCHS, the analysis of more cases and further candidates concerned with the development of the autonomic nervous system is required.[1]
