Introduction: Derivative chromosome is a rearrangement involving two or more chromosomes or the presence of multiple abnormalities in a single chromosome and always contains intact centromere. Segmental anomalies such as inversion or translocation in derivative chromosome may result in partial duplication or deletion during meiosis. Chromosomal translocations usually result in miscarriage and multiple anomalies (common neurodevelopmental defects, growth retard...

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:...

Background: The most common reason for the increased mortality and morbidity in TS, which results from partial or complete deficiency of an X chromosome in a female, is acquired cardiovascular disease, which is the result of endothelial dysfunction that causes atherosclerosis. Endocan, an inflamatory marker, has been found elevated in several diseases with endothelial dysfunction (ED). There is no study of endocan levels in TS.Ob...

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...

Itroduction: Thiamine responsive anemia (TRMA) known as Rogers syndrome; is an early-onset, autosomal recessive disorder characterized by diabetes mellitus, megaloblastic anemia and sensorineural deafness. Diabetes in this condition is well described in infancy but has only very rarely been reported in association with neonatal diabetes.Case: 3-months old male patient with neonatal diabetes was admitted to our outpatient clinic because of uncontrolled hy...

Introduction: Maturity-onset diabetes of the youth (MODY), is a genetically and clinically heterogeneous group of diseases in the pancreatic β–cell that impair insulin secreation. It mostly caused by heterozygous mutations in one of 11 different genes associated with β–cell function. The aim of this study is detection of the distribution of both known and novel point mutations of these genes in Turkish population.Pati...

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...

Background: Congenital hypothyroidism, one of the most important preventable causes of mental retardation, is a clinical condition characterized by thyroid hormone deficiency in newborns.Objective and hypotheses: Congenital hypothyroidism is most often caused by defects in thyroid development leading to thyroid dysgenesis. TSH receptor (TSHR) is the main known gene causing thyroid dysgenesis in consanguineous families with congenital hypothyroidism. In t...
