Gene Dosage Changes in the GCK Gene not Detected by Sanger DNA Sequencing in Two Patients with Phenotypic MODY 2

Birkebaek Niels H. , Brusgaard Klaus

Background: Maturity onset diabetes of the young 2 (MODY2) is phenotypically characterized by elevated fasting and post-prandial blood glucose (BG) levels and no diabetes auto-antibodies. Inheritance is autosomal dominant, and it is caused by variants in the glucokinase (GCK) gene with resetting of the pancreatic glucose sensor to a higher level. It is essential to detect MODY 2 patients as they do not require treatment.Objective...

Role of physical activity and sedentary behavior on early markers of cardiovascular disease in Canadian adolescents with and without type 1 diabetes: the CARDEA study

Harnois-Leblanc Soren , McNealis Vanessa , Friedrich Matthias G , Hulst AndraeaVan , Nuyt Anne-Monique , Bigras Jean-Luc , Barnett Tracie A. , Benedetti Andrea , Mathieu Marie-Eve , Drapeau Vicky , Sylvestre Marie-Pierre , Henderson Melanie ,

Background: Type 1 diabetes (T1D) is a risk factor for cardiovascular disease (CVD) and alterations may manifest as early as in adolescence. Increased physical activity and reduced sedentary behavior reduce the risk of CVD development in general adult populations, but knowledge is limited on their associations with early markers of CVD risk in pediatric T1D.Objective: Estimate associations of physical activity and sedent...

A Novel Mutation in 5’; Untranslation Region of Makorin Ring Finger 3 Gene Associated with the Familial Precocious Puberty

Lu Wenli , Wang Junqi , Li Chuanyin , Hu Ronggui , Wang Wei

Central precocious puberty (CPP) is the endocrine disorder triggering by many factors those can activate the hypothalamic-pituitary-gonadal axis early which controlled GnRH secretion. However, the mechanism of CPP has not been elucidated. The study of patients with familial CPP helped understanding the complex physiological processes. Recently, loss-of-function mutations in human Makorin ring finger protein 3 (MKRN3) were found to contribute to over 30% of cases of familial CP...

A De Novo Missense Mutation in the 4th Zinc Finger of the WT1 Gene Causes 46,XY and 46,XX DSD in Two Sibs

Bertalan Rita , Gellen Balazs , Eozenou Caroline , McElreavey Kenneth , Bashamboo Anu

The WT1 gene has a crucial role in the genesis of the bipotential genital ridge and subsequently in the specification of the Sertoli cells of testis. Mutations involving the WT1 gene are associated with a wide range of phenotypes impacting testis-determination and development including Denys-Drash syndrome, Frasier syndrome and Meacham syndrome. Here, we describe two sibs with DSD carrying a de novo mutation in the WT1 gene. A girl was born with Prader IV intersex genitals. Cy...

A Case of Familial Central Precocious Puberty Caused by a Novel Mutation in the Makorin RING Finger Protein 3 Gene

Grandone Anna , Cantelmi Grazia , Marzuillo Pierluigi , Cirillo Grazia , Luongo Caterina , Micillo Flora , Giudice Emanuele Miraglia del , Perrone Laura

Background: Central precocious puberty (CPP) is often familial but its genetic cause is largely unknown. Very recently, the makorin RING finger protein 3 (MKRN3) gene, located on chromosome 15 in the Prader-Willi syndrome (PWS)-associated region (15q11-q13), has been found mutated for the first time in five families with familial precocious puberty, with a peculiar kind of transmission. In fact, it is an imprinted gene which is expressed only if transmitted from the father. Th...

Can We Rely on Finger Stick Haemoglobin A1c? Comparison of Levels Assayed by DCA 2000 with IFCC Reference Method in a Paediatric Cohort

Tornese Gianluca , Milic Nadia , Spetti Laura , Gembrini Daniela , Loganes Carmen , Pellegrin Maria Chiara , Radillo Lucia , Radillo Oriano , Faleschini Elena , Ventura Alessandro

Background: DCA 2000 is still a very popular device to determine HbA1c levels in diabetes practices through a finger stick. It allows clinicians to give immediate feedback to patients and to make changes in diabetes management during the three-monthly assessment.Objective and hypotheses: To compare HbA1c values measured with DCA 2000 with corresponding values measured with IFCC (considered as the reference method) in a single paediatric centre, to assess...

Determining factors of a good response to treatment with growth hormone for the first 2 years

de Arriba Antonio , Cancela Vanesa , Juan Alcon Jose , Beisti Anunciacion , Ferrer Marta , Labarta Jose Ignacio ,

Objectives: - To establish the main factors on which a good response to GH treatment depends. - To study the optimum adherence values. - To study the impact of the loss of adherence in the treatment with GH.Materials and Methods: This is a non-interventional, retrospective observational study, by reviewing medical records of patients undergoing GH treatment for at least 2years due to GHD or SGA. Patients received treatment with Saizen&#1...

Severe Neonatal Donohue Syndrome: Extreme Hyperinsulinemia, Progressive Hypertrophic Cardiomyopathy (HCM) and Failure to Thrive

Lämmer Constanze , Langer Johanna , de Potzolli Brigitte , Liebl Stefanie , M.K. Völkl Thomas

Introduction: Donohue syndrome (DS) is presenting as the most severe form of insulin resistance. Most of the patients are dying within the first two years of life. As potential treatment has been described the administration of rhIGF1 (Mecasermin) to stimulate the pathway of insulin-like action. An improved metabolic control was reported with continuous subcutaneous administration of rhIGF1 instead of twice daily injections [Plamper 2018].<p class="abstext...

Circulating Makorin Ring Finger Protein 3 Levels Predict Central Precocious Puberty in Girls

Jeong Hwal Rim , Lee Hye Jin , Shim Yeong Suk , Kang Min Jae , Yang Seung , Hwang Il Tae

Background/aim: Puberty is a mysterious process about which much is as yet unknown. MKRN3 is involved in regulating the initiation of puberty by inhibiting gonadotropin releasing hormone (GnRH) secretion. This study evaluated the serum level of MKRN3 and investigated its diagnostic usefulness in girls with central precocious puberty (CPP). Changes in the MKRN3 concentration during GnRH agonist (GnRHa) treatment were also analyzed.Methods: In total, 41 gi...

Dujovne Noelia Vanesa , Dratler Gustavo , Pitoia Fabian , Felipe Laura , Ayarzabal Victor , Soria Ianina , Berger Malena , Belgorosky Alicia , Herzovich Viviana

Background: Antithyroid drugs (ATD) are recommended as the initial treatment in Graves disease in childhood and adolescence. Identification of predictive factors might lead to improve patient management by facilitating the identification of patients requiring long-term ATD or early alternative therapy.Objective and hypotheses: To assess the prevalence of signs and symptoms of hyperthyroidism in childhood and adolescence, to evaluate the rates of adverse ...
