Prevalence of IGT and T2DM in obese children * Erhardt, Molnár and Soltész 2002 ** Sinha et al NEJM 2002
Clinical manifestations of T1DM 1. Major symptoms (3P) polyuria polyuria polydypsia polydypsia Polyphagia Polyphagia 2. Others weight loss weight loss fatigue fatigue vulvovaginitis, balanitis vulvovaginitis, balanitis enuresis enuresis visual disturbances visual disturbances
Etiology (genetics) of T1DM HLA region ( 40-50% ) Insulin gene (10-15% ) CTLA4 PTPN22
The HLA Region (6p21.31) DP DQ DR B C A Class II (1.1 Mb) Class III Class I (2.2Mb) Complement and Cytokines Class I-like genes and pseduogenes Frequent Recombination is Rare Telomere Centromere Recombination is Rare (0.7Mb)
