Hyperinsulinaemic hypoglycaemia (HH) is also classically referred to as "nesidioblastosis". Heterogeneous clinical manifestation of the disease causes risk of late diagnosis or even misdiagnosis. In infants and children, it can lead to serious and permanent damage to the central nervous system, which leads to the manifesting mental retardation. HH is characterised by unregulated insulin secretion from pancreatic β-cells. This effect has been correlated with nine genes: ABCC8, KCNJ11, GCK, GLUD-1, HADH1, SLC16A1, HNF4A, HNF1A, and UCP2. Mutations in these genes were found in approximately 48% of cases. The genetic background of the remaining cases is unknown. Understanding the genetic basis of familial hyperinsulinism has changed the early look at the disease. It has allowed for the differentiation of specific types of the disease. Depending on which of the nine disease-associated loci bears a pathogenic mutation, they differ in phenotype and pattern of inheritance. This review provides a brief overview of the genetic mechanisms of HH and its possible clinical presentations.

The 1p36 deletion syndrome involves a phenotypic presentation that includes central nervous system, cardiac, and craniofacial anomalies. We report the case of a 21-year-old female patient with 1p36 deletion syndrome who was found to have noninsulinoma pancreatogenous hypoglycemia syndrome (NIPHS) after hospitalization for persistent falls. On admission, vital signs were normal and physical examination revealed a thin, nonverbal patient.

The best-known etiologies of hyperinsulinemic hypoglycemia are insulinoma, non-insulinoma pancreatogenous hypoglycemic syndrome, autoimmune processes, and factitious hypoglycemia. In 2009, a disease not associated with classic genetic syndromes and characterized by the presence of multiple pancreatic lesions was described and named insulinomatosis. We present the clinical and pathologic features of four patients with the diagnosis of insulinomatosis, aggregated new clinical data, reviewed extensively the literature, and illustrated the nature and evolution of this recently recognized disease.
