Autosomal dominant DICER1 mutations are among the causes of early-onset familial cancer. DICER1 mutation has been shown in pleuropulmonary blastomas as well as ovarian tumors, thyroid, parathyroid, pituitary, adrenocortical and testicular tumors. It is important to be aware of the risk for the development of other cancers in the follow-up of these cases.Cases: Case-1: Previously known to be healthy 8,5-year-old girl presented with compla...

Objectives: Type 1 diabetes mellitus (DM) is an autoimmune disease caused by the destruction of pancreatic beta cells. The frequency of Type 1 DM is increasing, and the highest incidence rate is in children under 5 years of age. It is estimated that children under the age of five will develop approximately 70% of the cases under the age of 15, with an increased incidence.In our study, we aimed to evaluate the demographic, clinical an...

Resistance to thyroid hormone (RTH) is a rare genetic disease caused by reduced tissue sensitivity to thyroid hormone. The hallmark of RTH is elevated serum levels of thyroid hormone with unsuppressed thyrotropin (TSH). The most common form of RTH results from minor defects in the ligand-binding domain of the TRb gene, resulting in impaired T3-induced transcriptional activity. This study aimed to characterize clinical and genetic features of THD suspected cases in our clinic. ...

Neonatal diabetes mellitus (NDM) is a rare form of monogenic diabetes presenting in the first 6 months of life. NEUROD1 is a transcriptional factor involved in the development of endocrine pancreas. A few patients with maturity onset diabetes of the young (MODY) due to heterozygous NEUROD1 mutations and only two cases with permanent NDM (PNDM) associated to neurological disorders and cerebellar hypoplasia due to homozygous mutations in the NEUROD1 gene have been reported.<...

Direk Gül , Tatli Zeynep Uzan , Şiraz Ülkü , Çiçek Dilek , Hatipoğlu Nihal , Kendirci Mustafa , Kurtoğlu Selim

Congenital hyperinsulinemia occurs due to inappropriate insulin secretion from beta cells of the pancreas. It is the most common cause of resistant and recurrent hypoglycemia in neonates and infants and the threatment is very difficult. Although the incidence is reported as 1/50000, it is seen more frequently in consanguineous countries. Patients may present with lethargy, nourishment, irritability and seizures. If it is not treated, severe hypoglycemia may result in severe ne...
