Evaluating Genotype-Phenotype Correlation using an in vitro Mutagenesis Model in Bi-Allelic Mutations Resulting in Extreme Hypophosphatasia Clinical Phenotypes

Uday Suma , Matsumura Tomohiro , Saraff Vrinda , Saito Shiho , Orimo Hideo , Högler Wolfgang

Introduction: Hypophosphatasia (HPP) characterized by reduced mineralization results from mutations in the tissue non-specific alkaline phosphatase (ALPL) gene. HPP is clinically variable with extensive allelic heterogeneity in the ALPL gene. We report the findings of in vitro functional studies following site-directed mutagenesis in bi-allelic mutations causing extreme clinical phenotypes; severe perinatal and asymptomatic HPP.<...

Polycystic Ovarian Syndrome in Adolescents: Utilising Discovery Proteomics and the Search for to Identify Novel Non-Invasive Biomarkers

Gunn Harriet , Forysth Vhari , Hällqvist Jenny , Viner Russell , Mills Kevin , Steinbeck Katharine

Background: Polycystic ovarian syndrome (PCOS) is common, affecting up to one-fifth of females. PCOS is associated with significant comorbidity including metabolic dysfunction, pro-inflammation and mood disorders. Despite this, it is poorly understood, and diagnosis and management remain challenging in adolescents. Proteomics enables the better understanding of disease mechanisms and facilitates the identification of novel biomarkers.<st...

Growth Hormone Deficiency (GHD): Assessing Burden of Disease in Children and Adolescents: The Growth Hormone Deficiency – Child Impact Measure (GHD-CIM)

Brod Meryl , Højby Rasmussen Michael , Vad Knud , Alolga Suzanne , Bedoin Jacques

Background: Children with growth hormone deficiency (GHD) may have to deal with practical, emotional, and functional difficulties. Unfortunately, to date, there is no condition specific measure of the impact of GHD for these children. The Growth Hormone Deficiency – Child Impact Measure (GHD-CIM) was developed according to FDA/EMA guidances to address this gap. There are two GHD-CIM versions: child self-report (PRO) for ages 9 to <13 years and observe...

Dual X-ray Absorptiometry in Children With Hypophosphatasia Treated with Asfotase Alfa: A Pooled Post Hoc Analysis

Simmons Jill H. , Rush Eric T. , Petryk Anna , Zhou Shanggen , Martos-Moreno Gabriel Á.

Hypophosphatasia (HPP) is a rare, inherited, systemic disease characterized by deficient tissue-nonspecific alkaline phosphatase activity. Common manifestations in children include impaired skeletal mineralization, short stature, and reduced physical function. Asfotase alfa is an enzyme replacement therapy approved for treatment of patients of any age with pediatric-onset HPP. The utility of dual X-ray absorptiometry (DXA) as a diagnostic tool or measure of treatment effective...

Clinical Outcomes in Primary Empty Sella (ES) Syndrome in Childhood-Onset Growth Hormone Deficiency: Data from KIGS (Pfizer International Growth Database)

Maghnie Mohamad , Carlsson Martin , Aydin Ferah , Camacho-Hübner Cecilia

Background: The incidence of ES in children varies greatly depending on the population surveyed, ranging from 1.2%-9% to 68% (children without and with known endocrinopathies, respectively). MRI is the main diagnostic tool for screening pituitary and in a previous KIGS study, 3.0% of patients with GHD were identified with ES and 7.8% with pituitary hypoplasia (Maghnie et al, EJE (2013).Aim: T...

Ectopic Posterior Pituitary, Polydactyly, Midfacial Hypoplasia and Panhypopituitarism Due to a Novel Heterozygous IVS11-2AC(c.1957-2AC) Mutation in GLI2 Gene

demiral meliha , unal edip , kardas burcu , demirbilek hüseyin , ozbek mehmet nuri

Objective: Glioblastoma 2 (encoded by GLI 2 gene), is an activating zinc-finger transcription factor, involved in the Sonic Hedgehog pathway and embryogenesis of diencephalon and distal extremities Heterozygous mutations of GLI2 gene cause a wide range of clinical phenotype known as holoprosencephaly and holoprosencephaly-like syndrome, pituitary insufficiency, mid-facial hypoplasia, and polydactyly. We, herein, report a novel heterozygous IV...

Is Serum Alkaline Phosphatase Useful in Assessing Rickets Severity on Radiographs in Children with X-Linked Hypophosphataemia on Conventional Therapy?

Uday Suma , Shaw Nick , Mughal Zulf , Randell Tabitha , Högler Wolfgang , Santos Rui , Padidela Raja

Introduction: Conventional treatment of X-linked hypophosphataemic rickets (XLH) involves administration of oral phosphate and vitamin D analogues. An important treatment goal is to heal rickets which is assessed by normalisation of serum alkaline phosphatase (ALP) levels and resolution of radiological signs of rickets.Objectives: To determine the usefulness of serum ALP in assessing disease severity on wrist and knee ra...

Growth Hormone Deficiency (GHD): Assessing Parent Burden for Child Growth Hormone Deficiency Treatment: The Growth Hormone Deficiency - Parent Treatment Burden Measure (GHD-PTB)

Brod Meryl , Rasmussen Michael Højby , Vad Knud , Alolga Suzanne , Bedoin Jacques

Background: Treatment for child GHD requires daily injections, which can be painful and disruptive. For most children, these injections are administered by an adult, usually their parent. Unfortunately, little is known about the burden that a child's treatment places on a parent. The GHD-PTB was developed according to FDA/EMA guidances to address this gap. Items were based on qualitative interviews of 31 parents of children with GHD, ages 4 to <13 year...

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...

Purpose: was to evaluate the interaction of caries risk indicators and metabolic control in children with type 1 diabetes mellitus.Methods: The study included 50 children with type 1 DM and 50 healthy controls. Diabetic children were classified into 3 groups: well, fairly, and poorly controlled based on glycosylated hemoglobin level. Personal, family data, medical and dental history were collected. Children were examined...
