Introduction: MODY; is a rare type of diabetes that occurs clinically and genetically due to a single heterogeneous gene defect. To date, 14 different genes have been identified. In order to develop a holistic genetic diagnosis approach to monogenic DM, it is aimed to investigate molecular genetic diagnosis and responsible candidate genes with targeted new generation sequence analysis and whole exome sequencing (WES) method.Metho...

Context: PPP2R3C encodes the B”gamma regulatory subunit of the protein phosphatase 2A (PP2A), which is a serine/threonine phosphatase involved in the phospho-regulation processes of mammalian cells. We have recently reported homozygous and heterozygous mutations in PPP2R3C in patients with syndromic 46,XY complete gonadal dysgenesis (MEGD syndrome) and impaired spermatogenesis, respectively. In this study, we have further investigated th...

Ovarian steroid cell tumors (OSCT) are rare sex cord stromal tumors of the ovary and comprise <0.1% of all ovarian tumors. We herein report a case of an OSCT in a 9 year old girl patient who presented with central puberty preocious unresponsive to gonadotrophine relasing hormon analog (GnRH) therapy. A 9 year old girl presented with breast development noticed 4 months ago and menarche 3 months ago. Her height was 141,5 cm (+1,3 SDS), body weight was 35.4 kg (+0.9 SDS) and...

Background: Aromatase inhibitors (AIs) have been suggested to slow down estrogen-dependent skeletal maturation in pubertal boys with short stature. In the literature, few studies evaluate the efficacy and safety of AIs in boys with growth hormone deficiency (GHD). Objective: To evaluate the auxologic effects and short-term laboratory profiles of combined AI and rhGH therapy in adolescent males with GHD.Subjects and Methods:</stro...

Background: It is well known that boys are heavier than girls at birth. Causes of this difference are thought to originate from the Y chromosome and as a result of androgen action. Although some studies showed that sex dimorphism in size at birth is dependent of fetal androgens, one study reported that it is not generated by action of androgens.Objective and hypotheses: To determine birth weight (BW) of children in different aetiologies of disorder of se...
