Background: In Silver-Russell Syndrome (SRS), it is known that puberty starts early, frequency of premature adrenarche increases and adrenarche progresses aggressively. However, data regarding gonadal functions and testicular development in males during pubertal period is still insufficient.Methods: Twenty-four cases (9F, 15M) who were followed-up with diagnosis of SRS between 1990-2020 were included in the study. The di...

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:...

Introduction: Family history is observed in approximately 10% of the cases with type 1 diabetes mellitus (T1DM). The most important gene that determines susceptibility is the human leukocyte antigen complex (HLA) on chromosome 6. In HLA genes; specific combinations of alleles at DR3, DR4, DRB1, DQA1 and DQB1 locus either predispose or protective for T1DM. In this study, we aimed to investigate the molecular genetic etiology by whole exome sequence (WES) analys...

Introduction: Crooke’s cell adenoma (CCA) is an aggressive subtype of corticotroph adenoma, it is usually large, frequently invades surrounding tissues, and is resistant to both surgery and radiotherapy.Case Report: A 13-year-old girl, admitted with weight gain for more than 3 months. Her height was 147.5 cm (-1.5 SDS), weight 58.5 kg (1.1 SDS), BMI 26.89 kg/m2 (2 SDS) and blood pressure was 100/78mmHg. Her i physical exa...

Background: Melanocortin receptor 2 (MC2R) is expressed in the adrenal cortex and has a major role in the control of the hypothalamic-pituitary-adrenal axis. It is reported that the ACTH receptor MC4R has an impact on premature adrenarche. The melanocortin signaling system is reported to have leptin mediated effect on the regulation of GnRH neuron activity and has an important role in the onset of puberty and fertility.Objective:...

Introduction: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders of adrenal steroidogenesis.Aim: The purpose of this study was to investigate genotype-phenotype correlation, clinical findings and long-term outcomes in patients with CAH due to 11β-hydroxylase deficiency (11β-OHD) and 21-hydroxylase deficiency (21-OHD).Paients and methods...

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...

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...

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...
