Neonatal cholestasis, hyperferritinemia, hypoglycemia and deafness: a diagnostic challenge

Research output: Contribution to journalEditorialAcademicpeer-review


Neonatal conjugated hyperbilirubinemia is a diagnostic challenge. A full term, small for gestational age boy presented with cholestasis, hypoglycemia, hyperferritinemia and severe bilateral deafness. Diagnostic work-up revealed two hereditary diseases: alpha-1-antitrypsin deficiency (PI*ZZ genotype) and autosomal recessive deafness type 3 (compound heterozygous MYO15A gene mutation). In addition, we found late hypoglycemia on full enteral feeding which complicated this case. Hyperferritinemia is an uncommon finding in newborn cholestasis without liver failure.
