Familial clustering of type-2 diabetes is well-known. In adults, the prevalence of diabetes is higher among patients with diabetic parents. The Framingham offspring study found that maternal and paternal diabetes conferred equal risk for offspring type-2 diabetes.

Objectives: We conducted this study to compare the clinical characteristics of children and adolescents with family history of type- 2 diabetes mellitus, in one or both parents, (FT2DM) with those without a family history of DM (NFT2DM).

Patients and Methods: This was a cross-sectional descriptive study to determine the clinical presentation and prevalence of beta cell autoimmunity (Anti GAD, anti-islet cell and anti-insulin antibodies), thyroid function (Free thyroxine (FT4) and TSH) and anti-thyroid peroxidase antibody (ATPO) and anti-tissue transglutaminase (ATT) in a randomly selected cohort of children and adolescent (< 16 years) with FT2DM ( n= 13) and compare them with those for children without family history of DM (NFT21DM ( n = 26) at their first presentation at Hamad General Hospital Diabetes Center, Doha, Qatar

Conclusion: In this study, FT2DM occurred more in males than females, after 10 years of age, and all presented with hyperglycemia without ketosis. Clinical and subclinical hypothyroidism occurred more in the NFT2DM and they had a higher prevalence of hypercholesterolemia and triglyceridemia.
