Effects of tiratricol treatment withdrawal in MCT8 deficiency: ReTRIACt Trial

Freund Matthijs , Chatterjee Krishna , van Geest Ferdy , van der Most Floor , Bowers Dominic , Persson Anders , J Bauer Andrew , Edward Visser W.

We introduce the ReTRIACt Trial (NCT05579327) of tiratricol (Triac) for MCT8-deficiency, a rare X-linked disease resulting from disordered thyroid hormone transport and characterized by profound neurodevelopmental delay and features of chronic peripheral thyrotoxicosis. The ReTRIACt Trial aims to verify the effects of tiratricol observed in previous studies. It is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the effects of tiratricol discontinu...

Carney complex 1 (CNC, OMIM# 160980) is an autosomal-dominantly inherited complex tumor predisposition syndrome associated with skin pigment abnormalities and neoplasms of heart, endocrine glands and other organs. CNC is caused by heterozygous constitutional loss-of-function variants in the PRKAR1A-gene. PRKAR1A codes for the cAMP-dependent protein kinase type I-alpha regulatory subunit, an enzyme that represents an integral part of protein kinase A (PKA) tha...

Introduction: Children with cancer are at increased risk of endocrine complications, especially children with a brain tumor. One of these late effects includes bone disorders (ranging from low bone mineral density (BMD) to osteoporosis). Children with a suprasellar Low Grade Glioma (LGG) may be especially at risk for bone problems due to exposure to multiple treatment modalities, hypothalamic dysfunction and/or decreased mobility in combination with vision los...

Albert , Dattani Mehul T. ,

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...

Background: Congenital adrenal hyperplasia (CAH) and long-term glucocorticoid treatment may be associated with an increased risk of developing cardiometabolic sequelae such as abnormal glucose homeostasis, hyperlipidaemia, hypertension, cardiovascular (CV) disease, obesity and osteoporosis.Objectives: To study the current practice amongst expert centres for assessing cardiometabolic outcomes in adult patients with 21-hyd...

High carbohydrate diet results in sex-specific differences in energy homeostasis in mice with PAPP-A2 deficiency

The growth hormone (GH)-insulin-like growth factor (IGF-1) system is essential for optimal human growth and energy homeostasis. Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease involved in the liberation of free IGF-1, leads to problems in growth and bone density in humans and mice. Patients with PAPP-A2 deficiency also present lower body mass and mild glucose intolerance. The present study aimed to determine the influence of 1 month of high carbohydr...

Genome-Wide Meta-Analysis Identifies a Novel Low Frequency STK39 Variant of Large Effect on Risk of Type 1 Diabetes

Background: The genetic etiology of Type 1 Diabetes (T1D) is well recognized, with over 60 loci being identified to date, mainly through genome-wide association studies (GWAS). Most of these genetic associations involve common variants, while a sizable portion of the missing heritability of T1D could be attributed to unidentified rare single nucleotide polymorphisms (SNPs) (minor allele frequency (MAF) < 5%). The recent availability of large human whole genome sequencing d...

Methylation of the C19MC microRNA Locus in the Placenta: A Mechanism whereby Maternal Body Size Links to that of the Child

Background: The C19MC locus microRNA gene cluster is imprinted in the placenta. Imprinted genes control prenatal development and placental functions, and are epigenetically regulated. The factors that affect the DNA methylation status of C19MC regulatory region are unknown, as is the impact of this differential methylation on the offspringÂ’s body size.Objectives: To study in humans 1) the association of placental C19MC DNA...

Background: Androgen excess in childhood is a common clinical presentation and might signify serious pathology. We have recently explored patterns and severity of androgen excess in a large female adult cohort to differentiate common polycystic ovarian syndrome (PCOS) from non-PCOS pathology, including congenital adrenal hyperplasia (CAH), ovarian hyperthecosis and adrenal and ovarian tumours (Elhassan et al., JCE&M 2018). Herein, we undertake a similar approach f...

Calcium signaling is fundamental to many cellular processes. An important pathway for increasing intracellular Ca2+ levels is store-operated Ca2+ entry (SOCE) regulated by stromal interaction molecule (STIM1-2), and Ca2+ channels formed by ORAI1-3 proteins. Mutations in the ORAI1 and STIM1 genes that abolish SOCE cause a combined immunodeficiency (CID) syndrome that is accompanied by autoimmunity and nonimmunologic symptoms. We present patients with Anhidrotic Ectodermal Dyspl...
