Introduction: A promoter mutation (c.167G>T) in the phosphomannomutase 2 (PMM2) gene, either homozygous or occurring in trans with a PMM2 coding mutation, causes hyperinsulinism (HI) and polycystic kidney disease (PKD) – HIPKD. Organ-specific deficiency of PMM2 leads to the restricted phenotype of HIPKD, without typical clinical features of the Congenital Disorder of Glycosylation Type 1a (CDG1a), which is caused by recessive coding ...

Background: Hyperinsulinaemic hypoglycaemia (HH) is the most frequent cause of severe and persistent hypoglycaemia in infancy. Prompt recognition and successful management are critical to ensure prevention of hypoglycaemic brain injury and neurological sequelae. The incidence of HH varies from 1:50,000-1:2,500, and mutations in at least 12 different genes involved in β-cell insulin release have been described. Recently, the spectrum of genetic causes for HH has been exten...
