We report the case of a 15-month-old male suffering from Late Onset Congenital Central Hypoventilation Syndrome and recto-sigmoid Hirschsprung's disease, an association that has not been reported thus far. Nevertheless, our patient showed a missense mutation of the PHOX2B gene already known in isolated late onset central hypoventilation, resulting in a substitution of the Ala140 residue with a Glu residue (p.A140E). The present association of LO-CHS and HSCR in a patient harboring a rare and atypical PHOX2B mutation allows to refine the mutational spectrum of this disease and suggests individualized ventilatory care along with specific surgical and oncological approaches.

Abstract

We report the case of a 15-month-old male suffering from Late Onset Congenital Central Hypoventilation Syndrome and recto-sigmoid Hirschsprung's disease, an association that has not been reported thus far. Nevertheless, our patient showed a missense mutation of the PHOX2B gene already known in isolated late onset central hypoventilation, resulting in a substitution of the Ala140 residue with a Glu residue (p.A140E). The present association of LO-CHS and HSCR in a patient harboring a rare and atypical PHOX2B mutation allows to refine the mutational spectrum of this disease and suggests individualized ventilatory care along with specific surgical and oncological approaches.
