Congenital hyperinsulinemia (CHI) is a genetically and clinically heterogenous disorder. In addition to the standard care of management of the proband, genetic counseling regarding the risk of recurrence in the future siblings is an important part in the management of the disorder. The counseling needs identification of accurate etiology and is challenging due to the complexity of the molecular mechanisms of CHI. This case highlights the importance of molecular testing which not only helped in planning the management of the proband with CHI but also helped in providing genetic counseling for which the family had consulted the medical genetics department.
