Abstract
Diabetes mellitus is a chronic metabolic disease with a rising trend of cases globally. While majority are polygenic in origin, monogenic forms account for 1-5 % of cases. Increased recognition of monogenic types is the outcome of a wider availability of molecular tests. With recent studies showing misdiagnosis of monogenic forms as type 1 or type 2 diabetes, it is crucial to clinically suspect these types with clinical and family history and to decide regarding the need for molecular tests. This article briefly describes the genetic aspects of various types of diabetes, systematic approach to a patient with diabetes and genetic counselling regarding the recurrence risks for both monogenic and polygenic forms of diabetes.
