Congenital hyperinsulinism is a rare manifestation of his Kabuki syndrome. However, early diagnosis is crucial to prevent neurological complications of hypoglycemia. There are 2 types of Kabuki Syndrome depending on severity of symptoms. Kabuki syndrome Type 1 is associated with heterozygous mutations in gene KMT2D. Kabuki syndrome Type 2 is inherited in an X-linked manner. It’s associated with heterozygous mutations in gene KDM6A and characterized by more severe course of the disease.
