Introduction: Turner syndrome (TS) is a genetic condition with different phenotypic expressions depending on karyotype. Due to genetic prenatal testing, its prevalence is getting lower. The objective was to analyze the presence of different comorbidities associated with TS according to the karyotype and evaluate if there is follow-up in adulthood.Methods: Descriptive retrospective study including all the patients genetic...

Background: Sitosterolaemia, or phytosterolaemia, is a disorder of increased plant sterol levels in the body leading to a variable presentation including hypercholesteremia, xanthoma, atherosclerosis and haematological manifestations. Although considered rare, the prevalence is likely underestimated due to the variable phenotype. It is caused by recessively inherited mutations in ABCG5 or ABCG8 which encode the sterol efflux transporters in the gut. Hyperchole...

Noonan syndrome (NS) is an autosomal dominant, variably expressed, multisystem disorder with an estimated prevalence of 1 in 1000–2500. In 2001, PTPN11 was the first gene associated to Noonan syndrome; now, at least 20 other genes have been discovered especially in the RAS–MAPK signalling pathway. More recently, missense mutations in RIT1 have been reported as causative of NS. A six-years female patient was referred to our Hospital for short stature (<-2 sds) an...

Background and Aims: Initial presentation of type 1 diabetes (T1D) is associated with different level of diabetic ketoacidosis (DKA). Four pancreatic islet cell autoantibodies (Abs) mostly associate with T1D - glutamic acid decarboxylase antibodies (anti-GAD65), tyrosine phosphatase antibodies (IA 2-Ab), insulin autoantibody (anti-IAA) and zinc transporter 8 antibodyAim: To evaluate the prevalence of DKA, the frequency o...

Introduction: The aim of this study was to investigate the molecular genetic etiology and to determine the relationship between genotype and phenotype with targeted next-generation sequence (NGS)analysis.Method: Patients with a clinical diagnosis of OI were included in the study. Initially, mutations in COL1A1 and COL1A2 genes which are known to be most responsible for OI were investigated. In the second step, a targeted...

Background: Turner syndrome is one of the most common chromosomal disorders and is seen in 1:2500 female live births. The disease manifests with various clinical features and can be classified according to karyotype as monosomy, mosaicism, numeric, and structural abnormalities.Objective and hypotheses: Patients with Turner syndrome have complicated with various manifestations congenital or acquired. In this study we aimed to emphasise the importance of a...

Background: Thyroid cancer is a very rare malignancy of childhood. Approximately they account for 1.5% of all cancers before 15 years of age. In our country, this rate is %0.4 before 20 years of age.Aims and objectives: To analyses the clinical features and treatment results of children with thyroid malignancy in Turkey.Methods: In this multicentric and retrospective study the demographic and clinical characteristics of 124 childre...

Background: Diagnosis and treatment of GH deficiency(GHD) in children are different between countries, and even among centres in the same country.Objective and hypotheses: To evaluate current practices in diagnosis and treatment of GHD in the process of preparing the new consensus on GHD by Turkish Society for Pediatric Endocrinology and Diabetes.Method: A questionnaire was sent out to all paediatric endocrinology centres.<p cl...

Background: Children with Turner syndrome (TS) have a specific growth pattern that is quite different from that of healthy children. Many countries have population specific growth charts for TS.Objective and hypotheses: Considering national and ethnic differences, we undertook this multicentered collaborative study to construct growth charts and reference values for height, weight, and BMI from birth to adulthood for spontaneous growth of Turkish girls w...

Background: Turner syndrome (TS) can manifest with various clinical features depending on the karyotype and the genetic background of affected subjects.Objective and hypotheses: The aim of this study was to evaluate growth parameters from birth to adulthood in girls with TS in a cross-sectional study.Method: A total of 842 patients, with an age of diagnosis ranging from birth to 18 years followed-up between 1984 and 2014, from 35 d...
