Background: Aromatase excess syndrome (AEXS) (OMIM 139300) is a rare condition characterized with gynecomastia in boys and macromastia in girls. Estrogen excess in boys can lead to prepubertal and pubertal gynecomastia, bone age progression and short adult stature. While most of girls are usually asymptomatic, there are few reported female patients with excessive breast growth, early puberty, menstrual irregularities, and short adult stature. Male and female children with AEXS...

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...

Background: Approximately 10-15% of small for gestational age (SGA) newborns are at risk of having subnormal growth and persistent short stature. It is postulated that a large amount of persistent short stature results from genetic abnormalities, which are commonly characterized by dysmorphic features and developmental disorders.Aim: To uncover the genetic etiology of syndromic short stature children born SGA.<p clas...

Background: Congenital hypothyroidism(CH) is the most common neonatal endocrinological disorder in the world. Although most of the CH is sporadic, some genetic defects are responsible from the etiology. The aim of this study was to determine the genetic and etiological factors of CH.Methods: 49 patients(female;n=24), from 24 families were included in the study. The data, collected retrospectively, consisted ...

Introduction and aim: Prader-Willi syndrome(PWS), is a genetic disorder caused by the absence of paternal genes located on chromosome 15q11.2-q13. In this multi-central study; patients with PWS were followed for 2 years. Initial clinical and laboratory findings, growth hormone(GH) treatments and their responses were evaluated.Patients and Methods: 54 patients from 10 pediatric endocrine centers were involved and data was...

Background: Rokineticin receptors (PROKR1 and PROKR2) belong to the family of G protein-coupled receptors. Bi-or mono allelic mutations in PROKR2 gene have been identified in Kallmann syndrome which is characterized by hypogonadotropic hypogonadism and anosmia/hyposmia. Recently, PROKR2 mutations were reported in patients with multiple pituitary hormone (MPHD) and growth hormone deficiencies (GHD), suggesting a potential role for the PROK2 p...

The optimal GH treatment for NS is still controversial. In this study, we aimed to evaluate the growth characteristics in addition to clinical features of NS, and the growth response to GH treatment by using a nationwide registration system.Material and methods: Children and a...
