Hyperinsulinemic Hypoglycemia, Familial, 4, also known as hyperinsulinism due to glutamodehydrogenase deficiency, is related to 3-hydroxyacyl-coa dehydrogenase deficiency and hyperinsulinemic hypoglycemia. An important gene associated with Hyperinsulinemic Hypoglycemia, Familial, 4 is HADH (Hydroxyacyl-CoA Dehydrogenase), and among its related pathways/superpathways are EML4 and NUDC in mitotic spindle formation and DNA Damage. The drugs Octreotide and Somatostatin have been mentioned in the context of this disorder. Affiliated tissues include pancreas and liver, and related phenotypes are decreased 3-hydroxyacyl-coa dehydrogenase level and neonatal hypotonia
