Timing of precocious pubarche in girls: Does a contemporary subgroup exist?

Tahmiscioglu Feride , Ercan Oya , Ozcabi Bahar , Evliyaoglu Olcay

Background: In 2012, a phenomenon of early isolated gonadotropin-independent thelarche among contemporary girls was reported.Objective and hypotheses: We wanted to evaluate whether a contemporary isolated early pubarche also exists. One way of looking into this is by investigating the age of pubarche in a group of girls with premature pubarche (PP) over time. If some girls had earlier pubarche, then, we would expect a subgroup (i.e. those younger than 8 ...

A Case of Vitamin D Dependent Rickets Type 1 with a Novel Mutation in CYP27B1 (25-OH Vitamin D-1-α-Hydroxylase) Gene

Ozcabi Bahar , Evliyaoglu Olcay , Ercan Oya , Tahmiscioglu Feride , Jaferova Sevinc , Oruc Cigdem , Adrovic Amra

Background: Vitamin D dependent type 1 rickets is a rare, autosomal-dominantly inherited disorder due to an inactivating mutation in CYP27B1 (25-OH vitamin D-1-α-hydroxylase) gene. It is characterized by early onset of rickets with hypocalcemia. We report a boy admitted with symptoms of hypocalcemia and who carried a novel mutation in CYP27B1 gene.Case: The patient was admitted with tetany at the age of 12 months. When he had his first convulsion, h...

Three Siblings with Corticosterone Methyloxidase Deficiency Type 2 due to c.1175T>C Mutation +a Novel c.788T>A Mutation in CYP11B2 Gene

Ozcabi Bahar , Evliyaoglu Olcay , Ercan Oya , Bucak Feride Tahmiscioglu , Adrovic Amra , Ceylaner Serdar

Background: Corticosterone methyloxidase deficiency (CMOD) type 2 is an autosomal recessive disorder which presents with salt loss and failure to thrive in early childhood. We present three siblings with CMOD type 2 whose genetic analyses revealed a known c.1175T>C mutation (homozygous) and a novel c.788T>A mutation (homozygous) in CYP11B2 gene.Case 1: The patient was admitted with salt loss and failure to thrive at the age of 6 months; ...

Do IGF1 Generation Test Results Predict 1st-Year Growth Response to GH Treatment in Idiopathic Short Stature?

Masoom Mohammad Ajmal , Ercan Oya , Bucak Feride Tahmiscioglu , Ozcabi Bahar Taskin , Evliyaoglu Olcay

Background: It is well-known that human GH (hGH) treatment increases growth rate in idiopathic short stature (ISS) in the short term which might predict the overall height gain. However,the fact that ISS might involve a heterogeneous group of individuals with individual benefits from hGH treatment makes the decision to treat or not to treat difficult.Objective and hypotheses: The aim of this study was to investigate retrospectively whether an IGF1 genera...

Thyroid Nodules in Childhood and Adolescence; Clinical, Radiologic and Etiological Evaluation

Evliyaoglu Olcay , Ozcabi Bahar , Tekin Ayse , Bucak Feride , Ercan Oya

Background: Thyroid nodules are less common in childhood but it has higher risk of malignancy. In this study, we aimed to evaluate children and adolescents with thyroid nodules, clinically, radiologically and histopathologically to determine etiologic distrubution.Method: Seventy-one patients (46 females) with the mean age of 10.41±5.03 (0.04–21) years with thyroid nodules were involved in this study. Patients were evaluated by their complaints...

46,XY Complete Gonadal Dysgenesis in a Familial Case with a Rare Mutation in the Desert Hedgehog (DHH) Gene

Neocleous Vassos , Fanis Pavlos , Cinarli Feride , Oulas Anastasios , Spyrou George M , Phylactou Leonidas A , Skordis Nicos

Purpose: Disorders of sex development (DSD) have been linked with gene defects that lead to gonadal dysgenesis. Herein, we aimed at identifying the genetic cause of gonadal dysgenesis in a patient with primary amenorrhoea and 46,XY karyotype from a consanguineous family.Methods and Results: Whole exome sequencing (WES) was performed and revealed in homozygosity the rare and only once reported p.Arg164Pro missense mutatio...

Next Generation Sequencing in GnRH Deficient Patients with Congenital Hypogonadotrophic Hypogonadism: Novel Findings in KAL1, SRA1, WDR11, FGFR1, CHD7 and PROP1 Genes

Abstract: Objective: Congenital hypogonadotropic hypogonadism (CHH) is a rare genetic disease caused by GnRH deficiency and characterized by absent or incomplete puberty with infertility. The identification of the genetic cause in this group of patients through the use of next generation sequencing (NGS) can assist to the clinical management.Methods: Seven GnRH deficient nonrelated Cypriot probands were ...
