Amino Acids Plasma Profile in Children with Type 1 Diabetes

Dura-Trave Teodoro , Cortes-Castell Ernesto , Moya-Benavent Manuel , Chueca-Guindulain Maria Jesus , Berrade-Zubiri Sara , Nogueira-Lopez Javier

Background: Insulin deficiency inhibits protein synthesis and stimulates protein degradation, and then amino acids metabolism could be altered in diabetes mellitus.Objective: The aim of this study is to analyze amino acid plasma profile in a group of children with type 1 diabetes, and to evaluate its potential application as markers of metabolic control of the disease.Subjects/Methods: A clinical assessment and metabolic study (ami...

Quality of Life and Anxiety in Adolescents with Differentiated Thyroid Cancer

Benoit Melissa Anne

Background: Clinical observations of children and adolescents with differentiated thyroid cancer (DTC) patients led us to investigate quality of life and anxiety. Although adult DTC survivors have similar or slightly worse quality of life (QOL), this has not been evaluated in the pediatric population.Objective and Hypotheses: In this cross-sectional pilot study, our objective was to compare QOL and anxiety in adolescents with DTC to patients with acquire...

Paternal Loss-of-Function Mutations of GNAS and Growth Retardation in a Mice Model: A Specific Placental Transcriptomic Signature?

Tran Lea Chantal , Ballandone Celine , Vaiman Daniel , Barbaux Sandrine , Richard Nicolas , Kottler Marie-Laure

Background: GNAS gene is a complex imprinted locus, resulting in the expression of at least four transcripts (XL, NESP55, A/B and Gsα) characterized by their specific exon 1 and common exons 2-13. While Gαs is biallelically expressed in most tissues, XL is only expressed from the paternal allele. Maternally inherited, loss-of-function mutations affecting those GNAS exons that ...

Loss of Function CYP24A1 Mutations in Patients with Hypercalcemia and Low Pth level: an Autosomal Dominant or Recessive Trait?

Molin Arnaud , Baudouin Roseline , Coudray Nadia , Figueres Marie-Lucille , Jones Glennville , Kottler Marie-Laure

Background: Homozygous or compound heterozygous mutations of gene CYP24A1 have recently been reported to cause idiopathic infantile hypercalcemia due to increased intestinal absorption of calcium. However, an autosomal dominant transmission with partial penetrance of the trait was also suggested.Objective and hypotheses: Evaluation of the frequency of CYP24A1 mutation and evaluation of the impact of heterozygous mutation on calcium meta...

Why understanding hemoglobin glycated measurement can be important: Santa Juana hemoglobin variant and falsely elevated HbA1c

Lorand Juan , Boutsen Laure , Gueulette Emmanuelle , Maisin Diane , Closset Mélanie , Mouraux Thierry , Beckers Dominique

Diabetes mellitus is a chronic disease. The risk of microvascular complications is correlated with hemoglobin A1c (HbA1c) level [1] Educating the diabetic patient to keep an HbA1c below 7% reduce the risk of long-term complications. We report the case of a 15 years old teenager, with chronical headache, referred for diabetes mellitus with a fasting glycemia of 83 mg/dl (normal < 100) and an HbA1C of 8.3% using an Ion-exchange High Performance Liquid Chromatography (HPLC, Ad...

Meta-analysis of Children with Multiple Endocrine Neoplasia (MEN) Type 2A from 1995-2014: Impact of RET Mutation Screening on Age at Thyroidectomy and Frequency of Metastatic Disease

Burckhardt Marie-Anne , Zumsteg Urs , Szinnai Gabor

Background: Medullary thyroid cancer (MTC) in MEN 2A is caused by mutations in RET. Guidelines (2001/2009/2015) recommend prophylactic total thyroidectomy (TT) based on mutation specific risk levels (ATA 2015: high/moderate).Objective: The aim of this study was to analyse changes of age at TT, frequency of metastatic MTC (MMTC), and frequency of TT according to guidelines since introduction of RET testing in 1995....

A Rare Cause of Short Stature: the Floating Harbor Syndrome

Kayemba-Kay's Simon , Maillet Odile , Heron Anne

Background: Short stature has several causes ranging from complex hormonal deficiencies mostly related to pituitary gland genetics, to idiopathic and environmental causes such as maternal smoking in pregnancy, etc. Floating harbor syndrome is a rare genetic disorder characterized by short stature, delayed bone age, mild to moderate mental retardation, retarded speech development, and typical facial dysmorphic features. The syndrome is caused by heterozygous mutations in exon 3...

Two French Families with Vitamin D Dependency Rickets Type 1B Harbor Homozygous Recessive Expression Of CYP2R1 Mutations L99P and G42_L46DEL INSR

Molin Arnaud , Feillet Francois , Demers Nick , Wiedemann Arnaud , Brennan S , Kaufmann Martin , Jones Glenville , Kottler Marie Laure

Vitamin D dependency rickets type 1B (VDDR-1B) is a rare condition classified as rickets due to inadequate 25-hydroxylation of vitamin D. In this study, we describe rickets and loss-of-function CYP2R1 mutations in 6/10 individuals tested from two unrelated families. Five patients in family 1 (F1) have homozygous L99P mutations; while one member of family 2 (F2) has novel homozygous mutations at G42_L46del insR. The mutations, as well as another variant M248I found in ...

Using Public Databases, ‘Virtual Controls’ and Geolocalization to Search for Environmental Correlates of Hypospadias

Valleron Alain-Jacques , Esterle Laure , Mouriquand Pierre , Meurisse Sofia , Valtat Sophie , Urology Centers HYPOCRYPT Network , Bougneres Pierre

Background: Incidence of hypospadias varies considerably across countries, ranging from 4 to 43 cases per 10,000 births. Environmental factors might explain these differences. The classical approach is to use case-control studies to identify these factors. However, this approach suffers from the unavoidable arbitrariness of the definition of controls, and of recall bias.Objective and hypotheses: To identify environmental markers of the place of birth of ...

Silver Russell syndrome: A Cause of Partial IGF1 Resistance?

Dufourg Marie-Noelle , Perin Laurence , Houang Muriel , Daubard Marie-Laure , Brioude Frederic , Bouc Yves Le , Netchine Irene

Background: Silver-Russell syndrome (SRS) is characterized by intrauterine and postnatal growth retardation, relative macrocephaly at birth, prominent forehead, severe feeding difficulties and body asymmetry. In around 50%, it is secondary to hypomethylation at the IGF2/H19 imprinted locus on 11p15 (11p15 LOM), and in 10% to a maternal disomy of chromosome 7 (mUPD7). Mechanisms of postnatal growth failure in SRS are not well understood.Objective and hypo...
