Guven Ayla , Yildirimoglu Canan

Background: B-Lymphocyte kinase gene (BLK) gene acts on insulin synthesis and secretion, and mapped locus on chromosome 8p23. Monogenic diabetes due to BLK gene mutation is very rare and it’s named as MODY11. We aimed to present differences in clinical, laboratory and treatment of the patients with BLK mutations.Methods: OGTT performed in six patients. A panel of 23 MODY genes was screened.

Context: Deficiency of 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) causes a very rare form of congenital adrenal hyperplasia (CAH) known as 3βHSD2 deficiency, which is a consequence of biallelic HSD3B2 gene defects. The estimated prevalence is less than 1/1,000,000 live births. Knowledge of comprehensive steroid metabolome patterns in 3βHSD2 deficiency is scarce.Objective: We aimed...
