Background: Approximately one-third of the central precocious puberty (CPP) cases have familial transitions. Although more than 30 genes related to puberty have been reported to date, only a few (KISS1, KISS1R, MKRN3, DLK1 and PROKR2) were associated with CPP. This study aims to reveal the associated sequence variants of MKRN3 and DLK1 genes in cases with familial CPP and their etiology.Method:...

Diagnosis of Cushing's Disease with Desmopressin-Induced Bilateral Inferior Petrosal Sinus Sampling: A Case Report

Bayrak Demirel Ozge , Derya Kardelen Al Asli , Yildiz Melek , Poyrazoglu Sukran , Bas Firdevs , Darendeliler Feyza

Background: Bilateral inferior petrosal sinus sampling (IPSS) is the gold standard for determining the source of hypercortisolism in ACTH-dependent Cushing's syndrome. Traditionally, IPSS is performed with CRH stimulation. Since CRH has been unavailable recently, intravenous desmopressin administration may be preferred during IPSS.Case Report: A 13-year-old boy presented with a weight gain of 10 kg and a decreased h...

Background: Patients with non-classical congenital adrenal hyperplasia (NCCAH) generally show a normal growth pattern and reach to their target height. However, short final height can occasionally occur. Here, we present a patient with NCCAH who reach his target height with additional therapy.Case Report: A 10.5-year-old boy was brought in due to pubic hair growth that had started before 6 months. He was born at 30 weeks...

Background: Neonatal diabetes mellitus (NDM) is a form monogenic diabetes diagnosed under 6 month of age.Objective and hypotheses: To describe the clinical and molecular features of NDM patients in a Turkish cohort.Method: Fifteen patients (13M, 2F) with diabetes onset before 6 months of age were included in the study. Clinical and molecular data were evaluated retrospectively.Results: Mean age at diagnosis w...

Associations of Vascular Biomarkers and the Somatotrophic Axis with Carotid Ultrasound and Echocardiography Findings in Relation to Turner Arteriopathy

Ucar Ahmet , Oz Fahrettin , Bas Firdevs , Oflaz Huseyin , Nisli Kemal , Tugrul Melike , Darendeliler Feyza , Saka Nurcin , Poyrazoglu Sukran , Bundak Ruveyde

Background: Turner syndrome (TS) is associated with increased arterial stiffness. To date, factors associated with the ontogeny of Turner arteriopathy remain unclear.Objective and hypotheses: To assess the associations of vascular biomarkers and the somatotrophic axis with arterial stiffness indices, and left heart size, in normotensive ‘dipper’ TS.Method: Sixty-one patients with uncomplicated normotentensive &#1...

Evaluation of Sitting Height/Height SDS in Patients with Turner Syndrome

Genens Mikayir , Kaya Gamze , Ulak Ceren Melis , Poyrazoglu Sukran , Bas Firdevs , Bundak Ruveyde , Saka Nurcin , Darendeliler Feyza

Background: Short stature and gonadal dysgenesis are the main characteristics in Turner syndrome (TS). There are conflicting reports about the body proportions in TS. Some studies described a proportionate short stature, whereas others reported disproportionately short legs. It is known that body proportions are genetically controlled and are different in different populations or ethnic groups.Objective and hypotheses: To evaluate body proportions assess...

Objective: To evaluate metabolic syndrome parameters in children with premature adrenarche (PA) during presentation in prepuberty and afterwards in puberty.Methods: 54 (48 femals, six males) patients (mean age 12.5±2.4 years) diagnosed with PA and followed until puberty were included in our study; as the control group 28(22 females, six males) (age, sex, puberty matched) healthy children (mean age 13.5±2.2 years) were taken. CAH was ruled out i...

Introduction: Loss-of-function mutations in genomically imprinted MKRN3 and DLK1 genes cause familial central precocious puberty (CPP) and may result in low serum concentrations of these proteins. This study aimed to evaluate the predictive value of serum MKRN3 and DLK1 concentrations for detecting variants in related genes.Material-Method: This retrospective study included 26 girls with CPP, of which 11 were receiving G...

Frasier syndrome with 46,XY gonadal dysgenesis diagnosed during etiological evaluation of nephrotic syndrome: A case report

Yanik Hasan , Koc Cansu , Sonmez Ferah , Uyanik Bulent , Derya Kardelen Al Asli , Yildiz Melek , Poyrazoglu Sukran , Bas Firdevs , Darendeliler Feyza

Background: Frasier syndrome (FS) is a rare inherited disease characterized by gonadal dysgenesis and progressive nephropathy, resulting from mutations in intron 9 splice donor site of the Wilms’ tumor suppressor gene 1 (WT1). It can be associated with 46,XY gonadal dysgenesis (female external genitalia with a 46,XY karyotype). Gonadoblastoma usually occurs in the second decade of life but can develop as early as 9 months of age in children with gonadal ...
