Abstract
A term baby developed hypoventilation on day 1 of life requiring mechanical ventilation and had subsequent difficulty in weaning. Diagnostic workup for pulmonary, cardiac, metabolic, sepsis and structural CNS diseases were negative. In view of persistent hypoventilation despite raised pCO2 levels in absence of any sedation, the diagnosis of Idiopathic. Congenital Central Hypoventilation Syndrome (CCHS) was considered. The baby was tested for Paired-like Homeobox 2B (PHOX2B) gene mutation and was found to have expanded alleles containing 10 polyalanine repeats producing genotype of 20/30 on chromosome 4p12 (The normal being 20/20). This is the first report of a neonate from India with genetically confirmed CCHS.
