Introduction: DICER1 syndrome is a pleotropic, autosomal dominant familial genetic tumor predisposition syndrome. DICER1 somatic + germ-line mutations (double hit hypothesis); cystic nephroma; pleuropulmonerblastoma, ovarian sex cord-stromal tumors, multinodular goitre (MNG) are associated with many conditions such as differentiated thyroid cancer, pituitary blastoma. We presented three cases, two of whom were siblings, who had been consulted because of no...

Introduction-Aim: MODY;It is an autosomal dominant, rare type of diabetes that occurs in young people as a result of mutations of beta cell function and genes involved in insulin secretion. The cases may be misdiagnosed as Type1 and Type2 diabetes. Considering that MODY is clinically and genetically heterogeneous, the findings should be evaluated correctly. It is important to define the clinical-laboratory characteristics of diagnosis and follow-up of patients...

Introduction: Growth hormone therapy (GHT); have been used in rare diseases such as growth hormone deficiency (GHD), panhipopituitarism (PHP), intrauterine growth retardation (IUGR), Turner Syndrome(TS) for many years while the effects of diagnostic timing on the treatment results are known. However,data on the diagnosis and treatment processes of these diseases are limited in our country. The aim of this study was to evaluate the results of diagnosis, follow-...

Aim: In this study, we planned to evaluate the patients with hyperprolactinemia etiology, clinical features and treatment responses.Material and Method: We evaluated retrospectively the features, clinical follow-up data and treatment responses of the patients with hyperprolactinemia in our pediatric endocrinology clinic between 01.01.2012-31.12.2018.Results: Thirty-one patients wit...

Introduction: Differential diagnosis should include congenital adrenal hyperplasia (CAH) in premature adrenarche patients. Clinically, it is possible to diagnose late onset and simple virilisation CAH caused by 21 hydroxylase deficiency because the criteria are better defined and genetic tests are widely available. But especially late onset 11 Beta hydroxylase deficiency can be very difficult to diagnose because the diagbostic criteria are not well defined and...

Introduction: Although the majority of the cases with obesity have a multifactorial etiology, rare monogenic forms of obesity exist. Several genetic disorders have been described that lead to early onset monogenic obesity. Leptin (LEP), leptin receptor (LEPR), melanocortin 4 receptor (MC4R), proprotein converting protein subtilisin / kexin-type 1 (PCSK1) and proopiomelanocortin (POMC) are the genetic mutations that have been most frequently shown to cause mono...

Background: Short stature homeobox-containing (SHOX) gene that strongly affects height. Due to high prevalence of SHOX gene mutations, in all children with unexplained short stature should be investigated to benefit from early growth hormone (GH) treatment. The aim of this clinical study was to determine the rate of SHOX haploinsufficiency in short stature patients and describe their anthropometric measurements.Methods: Between...

Introduction: Autoimmune polyendocrinopathy, candidiasis and ectodermal dystrophy (APECED) is a rare hereditary disorder with autoimmun manifestations affecting both endocrine and non-endocrine tissues. It is caused by mutations in the autoimmune regulatory (AIRE) gene which is defined by the presence of two of the three major components: Chronic mucocutaneous candidiasis, autoimmune hypoparathyroidism and Addison’s disease. Clinical manifestations may be developed during...

Introduction: Kisspeptin is a neuropeptide, encoded by the KISS1 gene, which acts upstream of gonadotropin-releasing hormone (GnRH) neurons and also has a critical role for maturation and function of the reproductive axis. Inactivating mutations of its receptor (KISS1R) cause normosmic isolated hypogonadotropic hypogonadism (IHH). In this report, we aim to present three siblings who have IHH due to novel compound heterozygous KISS1R mutation.Cas...

Aim: To evaluate thyroid function tests and affecting factors in twin and triplet newborns.Method: 655 newborns from 320 multiple gestations (305 twins/15 triplets) were evaluated retrospectively with respect to thyroid function tests (FT4, TSH). The effects of birth order, birth weight SDS, gestational age, maternal thyroid disease, gestational diabetes, assisted reproduction, dopamine were analysed.Results: Gestational age was 25...
