A Large Family with a Novel Mutation in the SCNN1A Gene Causing a Mild and Transient form of Autosomal Recessive Pseudohypoaldosteronism Type 1 (PHA1)

Efthymiadou Alexandra , Sertedaki Amalia , Chrousos George , Chrysis Dionisios

Background: PHA1 is a rare inherited disease characterized by resistance to aldosterone action and distinguished in two forms: the autosomal dominant renal form caused by mutations of the NR3C2 gene (MR) and the autosomal recessive systemic form caused by mutations of the subunit genes SCNN1A, SCNN1B, SCNN1G of the epithelial sodium channel (ENaC). The classic phenotype of the autosomal recessive form of PHA1 is usually severe, lifelong, and expressed with mu...

Osteoprotegerin and fT4 Levels in Subclinical Hypothyroidism of Childhood

Giannakopoulos Aristeidis , Katsantoni Elena , Efthymiadou Alexandra , Kritikou Dimitra , Chrysis Dionisios

Background: Osteoprotegerin (OPG) is a cytokine of the tumour necrosis factor receptor family, expressed in various cells types of the body including osteoblasts and endothelial cells. It acts as a soluble decoy receptor of RANK ligand preventing stimulation of osteoclastogenesis. In adults, subclinical hypothyroidism (SH) has been associated with cardiovascular complications. Furthermore several studies have linked OPG levels to increased cardiovascular risk.<p class="abs...

Adult Height Prediction by Bone Age Determination in Children with Idiopathic Growth Hormone Deficiency (IGHD): Analysis of KIGS Data

Reinehr Thomas , Carlsson Martin , Chrysis Dionisios , Camacho-Hübner Cecilia

Background: The precision of adult height prediction by bone age determination in children with idiopathic growth hormone deficiency (IGHD) is unknown.Patients and Methods: The near adult height (NAH) of patients with IGHD with prepubertal onset of growth hormone treatment (GH) in the KIGS database was compared to adult height prediction based on bone ages (BA) >7 years using the Bailey Pinneau (BP) or Tanner-Whiteho...

A Large Consanguineous Family with a Mild and Transient form of Autosomal Recessive Pseudohypoaldosteronism type 1 (PHA1) Caused by a Novel Mutation in the SCNN1A Gene: Functional Studies

Efthymiadou Alexandra , Gautschi I , vanBemmelen MX , Sertedaki Amalia , Chrousos George , Schild Laurent , Chrysis Dionisios

Background: PHA1 is a rare inherited disease characterized by resistance to aldosterone action and distinguished in two forms: the autosomal dominant renal form caused by mutations of the NR3C2 gene (MR) and the autosomal recessive systemic form caused by mutations of the subunit genes SCNN1A, SCNN1B, SCNN1G of the epithelial sodium channel (ENaC).

Weight Gain in Turner Syndrome: Association to Puberty Induction?

Reinehr Thomas , Lindberg Anders , Toschke Christina , Cara Jose , Chrysis Dionisios , Camacho-Hubner Cecila

Background: We have recently reported a BMI-SDS increase in girls with Turner syndrome (TS) treated with growth hormone (GH) (1).Objective and hypothesis: We hypothesise that puberty induction in TS is associated with weight gain.Method: We analysed the weight changes (BMI-SDS) of 888 girls with TS in the Pfizer International Growth Database (KIGS). Overweight was defined by a BMI >90th percentile and obesity by a BMI >97th...

A case of male pseudoermaphroditism (46,XY DSD) in an adolescent with a novel de novo NR5A1 gene variant.

Kostopoulou Eirini , Samkinidou Efstratia , Sertedaki Amalia , Efthymiadou Alexandra , Giannakopoulos Aristeidis , Hyun Seong-In , Lee Hane , Hun Seo Go , Chrysis Dionisios

Introduction-Purpose: In addition to chromosomal abnormalities, a number of genes have been implicated as causes of Disorders of Sexual Development (DSD). The NR5A1 (SF-1) gene expresses a transcription factor that plays a role in steroidogenesis by controlling multiple stages of adrenal and gonadal development, and its mutations have been reported in cases of DSD.Case presentation: A 152/12-year-old teenager ...

Background: Pediatric growth hormone deficiency (pGHD) is associated with growth attenuation/deceleration, short stature, delayed bone maturation, and metabolic defects. Daily recombinant human growth hormone (rhGH) treatment promotes linear growth and increases growth rate; however, it may present a substantial burden for patients and caregivers. This may lead to low adherence, limiting the clinical effect of treatment. This study assesses the health-related ...

Background: FOXE1 gene variants containing alterations in the alanine tract length may confer susceptibility to primary ovarian insufficiency (POI). BMP15 gene variants have also been related to POI.Objective and hypotheses: To evaluate the contribution of FOXE1 and BMP15 variants in the pathogenesis of POI and to investigate the hypothesis of digenic inheritance in this disorder.Method: FOXE1 and BMP...
