Antenatal Glucocorticoid Treatment and Polymorphisms in Glucocorticoid and Mineralocorticoid Receptor Genes are Associated with Long-Term Neurodevelopmental Outcomes in Preterm Survivors

van der Voorn Bibian , van der Pal Sylvia , Wit Jan , Meulenbelt Ingrid , Slagboom Eline , Rotteveel Joost , Finken Martijn

Background: Preterm survivors are found to exhibit deficits in several neurodevelopmental domains. It is unknown whether this could be explained by antenatal glucocorticoid treatment.Objective and Hypotheses: We studied whether antenatal glucocorticoid treatment is associated with behaviour and IQ in young adults born preterm. In addition, we studied whether these associations could be modified by the R23K and N363S polymorphisms in the glucocorticoid re...

An Open-Label Phase 2 Dose-Finding Study Comparing Three Different Doses of Weekly TV-1106 and Daily Recombinant Human GH (Genotropin®) in Treatment-Naive, Pre-Pubertal, GH-Deficient Children

Rosenfeld Ron G , Wit Jan M , Malievsky Oleg , Bolshova Elena , Brown Kurt , Sakov Anat , Anscheutz Gaya , Bassan Merav , Butler Kathleen

Background: TV-1106 (Teva Pharmaceuticals) is a genetically fused human GH and human serum albumin, in development for treatment of GH deficiency (GHD). TV-1106 has an extended duration of action compared to daily GH treatment and thus it is believed that treatment with TV-1106 can reduce the frequency of injections and improve compliance and quality of life for those requiring growth hormone replacement therapy. The efficacy and safety data from adult studies with TV-1106 sup...

Starting recombinant human growth hormone treatment at an early age improves adherence and catch-up growth in patients with growth disorders, and highlights the importance of the new guideline on referral of short children to paediatric care

van Dommelen Paula , Zoonen Renate van , Vlasblom Eline , Wit Jan M. , Beltman Maaike , Arnaud Lilian , Koledova Ekaterina ,

Background: The new preventive child health care guideline for referral of short/tall children facilitates early detection of growth disorders. Understanding the impact of early treatment initiation on recombinant human growth hormone (rhGH) adherence and catch-up growth can support the use of the guideline.Aim: To evaluate the impact of age at rhGH treatment start on adherence (≥85% vs <85% of prescribed doses...

Single nucleotide variations associated with short stature in Baka Pygmies as identified by Whole Exome Sequence (WES)

Bozzola Mauro , Zoccolillo Matteo , Lazarevic Dejan , Cittaro Davide , Manai Federico , Moia Claudia , Wit Jan M , Comincini Sergio ,

Introduction: Human growth is a multifactorial process involving genetic, hormonal, nutritional and environmental factors. Genome-wide association studies (GWAS) have shown that >400 genes are associated with adult height. African Baka Pygmies represent an isolated and well-confined small population with short stature of unknown etiology. In previous studies we reported an 8-fold reduced GH receptor gene expression and reduced serum levels of IGF-I and GHB...

Evidence that non-syndromic familial tall stature has an oligogenic origin including ciliary genes

Human growth is a complex trait. A considerable number of gene defects have been shown to cause short stature, but there are only few examples of genetic causes of non-syndromic tall stature. Besides rare variants with large effects and common risk alleles with small effect size, oligogenic effects may contribute to this phenotype. Exome sequencing was carried out in a tall male (height 3.5 SDS) and his parents. Filtered damaging variants with high CADD scores were validated b...

Objective: To describe clinical, laboratory and genetic characteristics of 42 short children from 34 consanguineous Turkish families.Design: Descriptive case series.Methods: After collecting clinical information, DNA samples were analysed in three European laboratories. In 18 children (12 families) suspected of a genetic defect in the growth hormone (GH)-insulin-like growth factor ...

Mutations in TBL1X as a Novel Cause of Familial Central Hypothyroidism

Background: Congenital central hypothyroidism (CeH) may occur isolated, or in combination with other pituitary hormone deficiencies. Although a third causative gene for CeH was recently reported (IGSF1), the aetiology of isolated CeH has remained unexplained in most cases.Objective and hypotheses: We hypothesized that in three relatives with unexplained isolated CeH a mutation in another gene might be responsible for the phenotype.<p class="...

Long-Term Outcome of a Male Preschooler Treated for Central Precocious Puberty

Foote Jan

Background: A 3.6-year-old Caucasian male presented with rapid onset of deep voice, facial hair, Tanner stage 2 testes, Tanner stage 3 pubic hair, penile length 9.5 cm, growth velocity (GV) 13.1 cm/year, and bone age 7 years. Evaluation was consistent with central precocious puberty and ruled out other pathology. Standard weight-based gonadotropin-releasing hormone agonist (GnRHa) therapy was initiated. GV increased to 16.6 cm/year, puberty advanced further, and bone age was 1...

De.Coding Obesity – Control of Metabolism by the Noncoding Transcriptome

Kornfeld Jan-Wilhelm

The pervasiveness of noncoding transcription has revolutionized our understanding of gene regulation. Although not yet fully catalogued in terms of numbers, mammalian genomes express a broad spectrum of, small and long, noncoding RNAs. Whereas small noncoding RNAs like microRNAs and their role in energy metabolism and glucose handling are rather well understood, we have little understanding concerning the metaboregulatory properties of those 10,000s of long noncoding RNAs (lnc...

Congenital Hypoaldosteronism of Unknown Etiology in Five Half-Siblings

Foote Jan , Cook Jennifer

Background: The children had normal 21-hydroxylase screening. An atypical form of congenital adrenal hyperplasia was initially suspected. The first child (female) had hyponatremia, hyperkalemia, elevated ACTH, and elevated androgens at birth. The second child (male) presented at 16 days with hyponatremia, hyperkalemia, normal cortisol, very elevated renin, low aldosterone, and elevated deoxycortisol. The third (female) and fourth (male) siblings had similar electrolyte abnorma...
