What causes rapid-onset obesity with hypothalamic dysregulation, hypoventilation, and autonomic dysregulation (ROHHAD)?

The exact cause of ROHHAD is unknown at this time. Several genes, namely the PHOX2B gene, the BDNF gene, and the TRKB gene (also called the NTRK2 gene), have been ruled out after consideration based on overlapping symptoms seen with ROHHAD, congenital central hypoventilation syndrome (CCHS), and preliminary animal studies.[1]
