Additional recommended knowledge

How to ensure accurate weighing results every day?

It codes for a homeodomain transcription factor. It is expressed exclusively in the nervous system, in most neurons that control the viscera (cardiovascular, digestive and respiratory systems). It is also required for their differentiation.

Pathology

Mutations in human PHOX2B cause a rare disease of the visceral nervous system (or dysautonomia): Ondine's curse or Congenital Central Hypoventilation Syndrome (or CCHS), which associates respiratory arrests during sleep, Hirschprung's disease (partial agenesis of the enteric nervous system) and tumors of the sympathetic ganglia.
