Abstract
Background
Congenital central hypoventilation syndrome (CCHS) is a rare condition that usually presents soon after birth and is potentially life-shortening if not treated. The defining abnormality is hypoventilation during sleep which requires life-long treatment with artificial ventilation. This syndrome may also be associated with generalised dysfunction of the autonomic nervous system and a sub-group with associated Hirschsprung’s disease. The genetic basis of CCHS has been identified as mutations in the PHOX2B gene.
Methods
We present four families, three with autosomal dominant inheritance and familial clustering, and one with a de novo mutation resulting in CCHS.
Conclusions
We demonstrate that nasal mask ventilation from birth can provide adequate treatment and improved quality of life for these children. Phenotypic variability in expression of disease is seen in families with the same mutations in PHOX2B gene. The psychosocial costs of the disease and the unrecognised ‘morbidity barter’ that is part of current management needs to be factored into in all stages of management from childhood to adolescence to adulthood.
