Computer-aided facial analysis as a tool to identify patients with Silver-Russell syndrome and Prader-Willi syndrome

Ciancia Silvia , Goedegebuure Wesley J. , Grootjen Lionne N. , Hokken-Koelega Anita C.S. , Kerkhof Gerthe F. , van der Kaay Danielle C. ,

Introduction: Genetic syndromes often show suggestive facial features that provide clues for the diagnosis. Considering the high number of genetic syndromes and the possible overlap of some features, memorizing facial gestalt is a challenging task for clinicians. DeepGestalt technology, and its app Face2Gene, has a growing impact on the diagnosis and management of genetic diseases by analyzing the features detected in one or more facial images of affected indi...

The Prader-Willi phenotype and atypical 15q11.2-q13 deletions

Grootjen Lionne , Juriaans Alicia , Kerkhof Gerthe , Hokken-Koelega Anita

Introduction: Prader-Willi syndrome (PWS) is a rare genetic disorder resulting from the lack of expression of the PWS region (locus q11-q13) on the paternally derived chromosome 15. Either a paternal deletion of the PWS region (50%), a maternal uniparental disomy (mUPD; 43%), an imprinting defect (4.1%) or translocation (<1%) can lead to PWS. Deletions are almost always de novo and manifest either as a large type I or a smaller type II deletion. In more rar...

Three years of growth hormone (GH) treatment in young adults with PWS previously treated with GH during childhood: Effects on cognitive functioning

Trueba - Timmermans Demi , Mahabier Eva , Grootjen Lionne , Juriaans Alicia , Hokken - Koelega Anita

Introduction: Most patients with Prader-Willi syndrome (PWS) have a mild to moderate cognitive impairment. Growth hormone (GH) treatment has positive short- and long-term effects on cognition in children with PWS. Few studies, however, have investigated the effects of GH on cognitive functioning in adults with PWS.Objective: To investigate the effects of 3 years GH treatment on cognitive functioning in young adults with ...

Long-Term Effect of Growth Hormone Treatment on the Onset and Progression of Scoliosis in Children with Prader-Willi Syndrome

Grootjen Lionne , Donze Stephany , Damen Layla , Rutges Joost , Hokken-Koelega Anita

Context: Most children with Prader-Willi syndrome (PWS) develop scoliosis. Scoliosis has a prevalence of 80% in children with PWS older than 10 years, who were not treated with growth hormone (GH). GH is an approved treatment for children with PWS and improves psychomotor development and body composition. The onset and progression of scoliosis are generally associated with an accelerated growth velocity and GH treatment might cause accelerated growth. Sinc...

Effects of age of start growth hormone treatment in children with Prader-Willi syndrome: The earlier the better?

Grootjen Lionne , Timmermans Demi , Damen Layla , Kerkhof Gerthe , Hokken-Koelega Anita ,

Context: Clinical findings characterizing PWS are muscular hypotonia, abnormal body composition, developmental delay, behavioral problems, hyperphagia with obesity when food intake is not restricted and short stature. Endocrine problems are described, like hypogonadism, hypothyroidism and adrenal insufficiency and growth hormone (GH) deficiency. Hypothalamic dysfunction may be responsible for many features of PWS. Randomized controlled studies showed that GH t...

Renal Involvement ın Obese Children and Adolescents

Kaya Mehmet Sirin , Anık Ahmet , Unuvar Tolga , Sonmez Ferah

Background and aim: Epidemiologic studies have been shown that obesity increases the risk of renal disease and it impact on prognosis. In this study, we aimed to investigate both glomerular and tubular involvement in asymptomatic obese children and to investigate the association of metabolic-anthropometric parameters with renal parameters.Material-method: Children with BMI ≥95th percentile and diagnosed as primary obesity (n=43) were inclu...

Clinical findings in three Japanese patients with N-acetylneuraminic acid synthetase-congenital disorder of glycosylation (NANS-CDG)

Background: N-acetylneuraminic acid synthetase-congenital disorder of glycosylation (NANS-CDG) is a recently established rare autosomal recessive disease caused by pathogenic variants in NANS involved in the biosynthesis of N-acetylneuraminic acid (the most common member of sialic acids). Sialic acids are ubiquitously distributed in the body including the brain and skeletal system, and are required for the development and function of multiple organs/tissues. C...

Pancreatic N-Methyl-D-Aspartate Receptors as Novel Drug Targets for The Treatment of Diabetes Mellitus

Background: N-methyl-D-aspartate receptors (NMDARs) are ionotropic glutamate receptors that are widely expressed in the CNS where they play an important role in neurotransmission and cell viability and serve as drug targets for the treatment of neurodegenerative disorders.Objective and hypotheses: Much less is known about the role of pancreatic NMDARs. Since neurons and pancreatic islets have many features in common, we hypothesiz...

Novel Association between the Non-synonymous A803G Polymorphism of the N-acetyltransferase 2 Gene and Impaired Glucose Homeostasis in Obese Children and Adolescents

Marzuillo Pierluigi , Grandone Anna , Di Sessa Anna , Umano Giuseppina Rosaria , Cirillo Grazia , Perrone Laura , del Giudice Emanuele Miraglia

Background: The N-acetyltransferase 2 (NAT2) A803G polymorphism leading to substitution of lysine to arginine at residue 268 and codifying for a cytosolic enzyme catalysing acetyl-CoA-dependent N- and O-acetylation reactions, has been associated with decreased insulin sensitivity in a large adult population with the A allele associated with insulin resistance (IR)-related traits.Objective and hypotheses: We screened for this polymorphism, for th...

Effects of Exposure to the Endocrine disruptor di(n-butyl) Phthalate on Testicular Dysgenesis Fetal Germ Cell Development in the Rat and in Human Fetal Testis

Mitchell Rod , van den Driesche Sander , Hrabalkova Lenka , Anderson Richard , McKinnell Chris , MacPherson Sheila , Calarrao Ana , Sharpe Richard

Background: Phthalate exposure results in endocrine disruption by inhibiting steroidogenesis, inducing focal dysgenesis and disrupting germ cell development in the rat fetal testis. Whilst phthalate exposure does not reduce testosterone production by the human fetal testis, its effects on germ cells and induction of dysgenetic areas in the developing human testis are less well described.Objective and Hypotheses: To determine the effects of phthalate expo...
