Background: Despite different genetic backgrounds, Noonan syndrome (NS) shares similar phenotype features to Turner syndromes (TS) such as short stature, webbed neck and congenital heart defects. The primary cause of short stature in Turner syndrome and Noonan syndrome is GH resistance [1]. Recombinant human growth hormone (rhGH) is being used to promote linear growth in short children with Noonan syndrome. However, its efficacy is still controversial.<p c...

Background: Studying patients with rare Mendelian diabetes has highlighted molecular mechanisms regulating β-cell pathophysiology. Previous, experimental studies have shown that Class IIa histone deacetylases (HDAC4, 5, 7, and 9) modulate mammalian pancreatic endocrine cell differentiation, function and finally glucose homeostasis.Methods: We performed exome sequencing in one adolescent boy with non-autoimmune di...

Background: There is increasing evidence from epidemiological studies that some man-made chemicals present in the environment can disrupt endocrine homeostasis in exposed humans. Exposure during foetal life to e.g. phthalates has been linked to adverse effects on testicular and ovarian development, thyroid homeostasis and growth in postnatal life. Exposure to phthalates fluctuates not only from day to day but also over time which poses a major challenge for ex...

Introduction: Neonatal diabetes, defined as the onset of diabetes within the first six months of life, is very rare disease. Several genetic factors caused to neonatal disease have been identified to date. PTF1A (pancreatic transcription factor 1a) play a key role in early pancreas development and cerebellar neurogenesis. Biallelic mutations in PTF1A have been reported in patients with pancreatic and cerebellar agenesis, whereas mutations loc...

Background: Kinase suppressor of Ras 2 (KSR2) gene codes for a scaffold protein modulating intracellular pathways that involve MEK/BRAF cascade and AMPK signaling. KSR2 plays an important role in energy balance regulation, and KSR2 mutations were reported to be associated with obesity and insulin resistance in mice and humans. In transfected cells, several KSR2 mutations lead to impaired fatty acid oxidation, which improved under met...

Introduction: Neurotensin is a 13 amino acid peptide with central and intestinal effects. It has been shown to decrease intestinal and gastric motility, increase the absorption of fat by regulating the release of pancreas and bile acid. In addition, it is reported that there is also an anorexigenic effect of the neurotensin released from the central nervous system. In the literature, conflicting results related to serum / plasma neurotensin levels were reporte...

Introduction: X-linked adrenoleukodystrophy (X-ALD) is a rare autosomal recessive neurodegenerative disease caused by a mutation in the ABCD1 gene. Although its clinical presentation varies, X-ALD is generally characterized by progressive demyelination of the central nervous system, primer adrenal insufficiency, and elevated plasma very long-chain fatty acid (VLCFA) levels. Herein, we aimed to present a case of X-ALD with normal VLCFA caused by a path...

Objective: Fetuin-A has many different functions due to its ability to bind to different toll-like receptors in different tissues. Working in different groups will contribute to our understanding of the pathophysiology of Fetuin-A. In this study, we aimed to evaluate Fetuin-A levels in obese adolescents and the relationship between Fetuin-A and anthropometric data, insulin levels and high sensitivity CRP(HSCRP). Material and Meth...

Introduction: Proopiomelanocortin (POMC) deficiency is a rare disease characterized by central adrenal insufficiency, early-onset obesity, red hair, and impaired skin pigmentation. This disease is caused by mutations of POMC that is localized in 2p23.3. Here, we aimed to present a case with central adrenal insufficiency, red hair, and rapid weight gain and who was detected frameshift mutation in the POMC.Case</s...

Introduction: Testicular regression syndrome (TRS) is a rare disease characterized by testicular dysfunction that causes varying degrees of virilization defect according to the emergence period in fetal life. The majority of cases present with normal male external genitalia. However, ambigious genitalia or, more rarely, female external genitalia can be found depending on the extent and timing of the intrauterine accident. Here, we present a case of TRS with no...
