Filibeli Berna Eroglu , Çatli Gönül , Manyas Hayrullah , Ayranci Ilkay , Kaya Özge Özer , Dündar Bumin

Introduction: An activating mutations in the ABCC8 gene cause both transient and permanent neonatal diabetes mellitus (DM) or MODY 12. In relation to the variant in the ABCC8 gene, patients may also present with either neonatal hyperinsulinism and/or DM later in life. Besides, the same variant can cause different phenotypic features among family members. Response to the sulfonylurea treatment may vary between patients.<...

Filibeli Berna Eroglu , Çatli Gönül , Ayranci Ilkay , Manyas Hayrullah , Kirbiyik Özgür , Dündar Bumin

Introduction: Heterozygous loss-of-function mutations in the glucokinase (GCK) gene cause MODY 2. Conversely, homozygous loss-of-function mutations in the same gene give rise to permanent neonatal diabetes mellitus (DM). Previously, two patients diagnosed with DM in adolescence and had homozygous GCK mutations were reported. Variants in these patients have been shown to exhibit inactivated kinetics that are indistinguishable from neonatal ons...

Gender uncertainty is stressful condition for children and their families. Gender assignment in children with disorder of sex development (DSD) is considered as a medical emergency. Influencing factors to consider when debating gender assignment include medical diagnosis, external genital appearance, potential of fertility and sexual, therapeutic and/or surgical intervention options, views and desires of patients and families, situation of social-cultural factors, the psycholo...

A Rare Cause of 46, XX ovotesticular DSD: Tetragametic Gonadal Chimerism

Uçar Ahmet , Güran Tülay , Eren Funda , Dokucu Ali Ihsan , Sahin Süleyman , Tanik Canan

Introduction: Virilization and hirsutism are clinical findings of androjen excess in females mostly due to polycystic ovary syndrome, although androgenic drugs, nonclassic congenital adrenal hyperplasia and androgen secreting adrenal/ovarian lesions are also implicated. 46, XX ovotesticular disorder of sex development (DSD) is the rarest form of DSD with an incidence of less than 1 in 20000.Case report: A 15-year-old ado...

Congenital hyperinsulinemia occurs due to inappropriate insulin secretion from beta cells of the pancreas. It is the most common cause of resistant and recurrent hypoglycemia in neonates and infants and the threatment is very difficult. Although the incidence is reported as 1/50000, it is seen more frequently in consanguineous countries. Patients may present with lethargy, nourishment, irritability and seizures. If it is not treated, severe hypoglycemia may result in severe ne...

Introduction: Autoimmune polyglandular syndrome type 1 (OPS1) is characterized by chronic mucocutaneous candidiasis, hypoparathyroidism and autoimmune adrenalitis. The mutations in the localized autoimmune regulator gene (AIRE) at 21q22.3 present the etiological cause.Objective: In this case report, two siblings case who were diagnosed with OPS1 with different clinical findings except classic triad were presente...

Introduction: Gain-of-function mutations in KISS1 and KISS1R genes and loss-of-function mutations in the gene encoding the makorin RING-finger protein 3 (MKRN3) expressed only in the paternal allele are the most common genetic reasons of familial central precocious puberty (CPP).Aim: We report a case of familial CPP and a pathogen variant in the MKRN3 gene.<stron...

Developmental Regulation of Obestatin and Adropin in Prader-Willi Syndrome and Non-Syndromic Obesity: Associations with Weight, BMI-z, HOMA-IR, and Lipid Profile

Orsso Camila E , Butler Andrew A , Muehlbauer Michael J , Cui Huaxia N , Rubin Daniela A , Pakseresht Mohammadreza , Butler Merlin G , Prado Carla M , Freemark Michael , Haqq Andrea M

Background: The peptides obestatin and adropin are thought to regulate glucose and lipid metabolism, weight gain, and fluid intake in adults. The roles of obestatin and adropin in the regulation of weight and glucose and lipid metabolism in Prader-Willi syndrome (PWS) and non-syndromic pediatric obesity are poorly understood. This study compares the concentrations of obestatin and adropin in infants and children with PWS and age- and BMI-z matched controls, and explores the as...

Background: Maternal overweight/obesity during pregnancy and excessive gestational weight gain (GWtG) have been recognized as important early-life risk factors for childhood obesity. We aimed to examine whether maternal BMI at 20 weeks of gestation and excessive GWtG were associated with alterations in body composition and metabolism in childhood in the offspring of primiparous mothers who participated in a randomised controlled trial of exercise regimen during pregnancy.<...
