Background: GNAS 1 gene (guanine nucleotide binding protein, alpha stimulating) encodes the alpha subunit of the stimulatory guanine nucleotide-binding protein (G-protein). Variations in the GNAS 1 can cause several disorders including Pseudohypoparathyroisism Type 1A (PHP1A), Type 1B (PHP1B), Type 1C (PPHP1C), Progressive Osseous Heteroplasia (POH), Pseudopseudohypoparathyroidism (PPHP) and McCune-Albright syndrome (MAS).Objectives: To report 2 patients...

Background: Molecular defects are rarely detected in Premature ovarian insufficiency (POI) patients.Objective and Hypotheses: We hypothesized that the frequency of causative molecular defects could be higher in cases with early onset of POI. Moreover, the analysis of multiple genes in the same POI group could disclose co-existence of more than one molecular aberration.Method: In 25 subjects, aged 17.1±7 years at POI onset, bid...

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...

Aim: Case report of an 18-month-old child with a background of vitamin D dependent rickets type 1(VDDR1)], due to a mutation of CYP27B1 (c.1319_1325dup and c.335C>T: compound heterozygote).Methods: Presentation of the case and the management of hypocalcemia as well as the complications of follow-up.Results: The patient presented at the A&Es of the 2nd Department of Pediatric...

Background: Hereditary multiple exostoses (HME) is an autosomal dominant heritable disorder characterized by exostoses located mainly in the long bones of extremities. HME is caused by mutations in two genes: EXT1, EXT2.Objective and hypotheses: Growth hormone (GH) deficiency is very rare in children with HME and GH replacement therapy has not been well described.Method: A 12.5 years old girl was referred to our Department because ...

Background: Wolf–Hirschhorn syndrome (WHS) is caused by variably-sized deletion of chromosome 4 involving 4p16 whose typical craniofacial features are ‘Greek warrior helmet appearance’ of the nose, microcephaly and prominent grabella. Almost all patients show mental retardation and growth delay.Case presentation: We report on a patient carrying a 4p16 deletion and GH deficiency treated with recombinant human GH (rhGH). The patient is male,...

Introduction: Germline mutations in Phosphatase and tensin homolog (PTEN) gene (chromosome 10q23) lead to PTEN Hamartoma Tumor Syndrome (PHTS), which includes Cowden syndrome. PTEN encodes a tumor suppressor protein that is a negative regulator of PI3K – Akt signaling pathway, taking part in multiple biological processes, including cellular cycle and regulation of metabolism.Materials and Methods:...

Background: Endocrine disorders associated with tall stature in childhood are frequently evaluated by Pediatric Endocrinologists. The most common non-endocrine genetic cause of tall stature, Marfan syndrome, is a rare autosomal dominant genetic condition of the connective tissue, which presents with specific dysmorphic features, including thin physique, long extremities and normal growth rate. Little is known regarding the association of Marfan syndrome with o...

Introduction: Adolescent obesity is often characterized by comorbidities with cardiovascular effects in adulthood. Treatment options for these conditions are limited during adolescence. Basic research in animals and clinical data in adults have shown that Crocus Sativus (Krokos Kozanis) has a beneficial effect on dyslipidemia, obesity and type 2 diabetes.Aim: The study of the lipidemic profile in fasting state, in adoles...

Introduction: Neurofibromatosis type 1 (NF1) is an autosomal dominant multisystemic neurocutaneous disorder characterized by an increased risk of benign and malignant tumor formation (neurofibromas, glioma and gastrointestinal stromal tumor). The incidence has been described to be around 1 in 2,500–3,500 live births, and the estimated prevalence is 1 in 4,000–5,000. Although it was first described by von Recklinghausen in 1882, the formal diagnostic criteria were pub...
