Defects in QSOX2, a novel regulator of STAT5B nuclear import and transcriptional activity, lead to severe post-natal growth restriction

Maharaj Avinaash , Andrews Afiya , Chatterjee Sumana , Hwa Vivian , Storr Helen

Background: Growth Hormone Insensitivity (GHI) is characterised by short stature and functional IGF-I deficiency associated with normal/elevated GH levels. Marked genetic and phenotypic heterogeneity exist, and heritable defects in GH-IGF-I axis genes/associated pathways account for mild-moderate to severe GHI cases. We report twin brothers from a non-consanguineous kindred who present with short stature and bi-allelic mutations in QSOX2 encoding the nuclear m...

A single-centre evaluation of remote video consultation for children and young people with diabetes

Andrews Edward , Odeleye Esther , Kumaran Anitha , Trevelyan Nicola ,

Background: Throughout 2020 telemedicine was rapidly deployed across health services and, during the COVID-19 pandemic, replaced many face-to-face (FTF) medical consultations. Children and young people (CYP) with diabetes present a unique opportunity for this type of consultation, due to the ability to interpret and share glucose data via other platforms. This study describes both CYP and parent experience of a new telemedicine service for CYP with diabetes.</...

Congenital Hypothyroidism: Neonatal SCREENING PROGRAM with T4 and TSH

Chueca Maria J. , Moreno Paula , Dura Teodoro , Berrade Sara , Andres Carlos , Garcia Maria Dolores , Moreno Jose Carlos , Ascunce Nieves

Objectives: -To determine children diagnosed with central congenital hypothyroidism (CCH) by a screening program using TSH and total T4 between May 2016 and January 2019.-To analyze the characteristics of the disease in these children.Material and Methods: During the time of the study, 14.743 newborns have been screened. Cut-off points are used for TSH ≥10MU/ml and T4 6 and 20 mg/dl as lower ...

Thyroid Function in Children Treated with rhGH for GH Deficiency

Triantafyllou Panagiota , Georeli Irene , Dimitriadou Meropi , Maliahova Olga , Daflos Anreas , Christoforidis Athanasios

Background: The relation between thyroid function and treatment with recombinant human GH (rhGH) has been the subject of many studies which indicate a decrease of fT4 levels and a compensatory TSH increase at rhGH therapy onset. On the other hand, we have identified a number of patients with documented primary hypothyroidism (either on treatment with L-thyroxine or not) before the onset of rhGH treatment.Objective and hypotheses...

Development of Novel Non-Invasive Strategies for Monitoring of Treatment Control in Patients with Congenital Adrenal Hyperplasia

Introduction: Glucocorticoid treatment remains a challenging aspect in the management of congenital adrenal hyperplasia (CAH). Current strategies for monitoring treatment are suboptimal and rely largely on frequent blood tests, which are traumatising in children and young persons (CYP). Recent evidence indicates a crucial role of 11-oxygenatedC19 androgens in the pathogenesis of CAH.Aim: To explore the use of 11-oxygenat...

Disrupting the Norm: The Experience of Young People with DSD

Steers Denise , Andrews Georgia , Collings Sunny , Ballantyne Angela , Stubbe Maria , Wiltshire Esko

The experiences of older adults with Variations in Sex Characteristics (VSC or Differences/Disorders in Sex Development/DSD) are well documented. However there has been a gap in the literature with respect to representing the voices of younger people. This qualitative research study has been conducted in collaboration with Intersex Trust Aotearoa New Zealand. Ten young people with VSC were recruited via health professionals, intersex advocates, support groups and social media ...

A complex phenotype due to the overlap of two rare conditions: miller-mckusick-malvaux (3M) and chung-jansen syndrome

Chiarito Mariangela , Giordano Mara , Mellone Simona , Urbano Flavia , Felicia Faienza Maria

Introduction: I. was born at term by emergency caesarean delivery due to foetal distress, by unrelated parents. Birth weight: 2160 g (-3.18 SD), length 41.5 cm (-4.47 SD), head circumference 35.4 cm (0.57 SD). He was admitted in the neonatal intensive care unit (NICU) for the severe growth retardation associated to dysmorphic features. Neonatal screening, echocardiography and brain ultrasound normal. Karyotype: 46,XY.Case present...

A rare heterozygous IGFI variant causing impaired IGF-I cleavage and postnatal growth failure: a novel disease mechanism with insights into IGF-I physiology

Cottrell Emily , Andrews Afiya , Williams Jack , Chatterjee Sumana , Edate Sujata , A. Metherell Louise , Hwa Vivian , L. Storr Helen

Background: Pathogenic IGFI gene mutations causing childhood growth failure are rare. Only 5 autosomal recessive mutations, one IGFI copy number variant and 2 heterozygous frameshift mutations are reported. Heterozygous missense IGFI mutations have not previously been described.Objectives: To identify and functionally characterise a novel missense IGFI variant in a patient with postnat...

Novel dominant negative GH receptor variants provide important insights into GH receptor physiology

Andrews Afiya , Cottrell Emily , Maharaj Avinaash , Ladha Tasneem , Williams Jack , Metherell Louise A , McCormick Peter J , Storr Helen L ,

Background: Growth hormone insensitivity (GHI) encompasses normal/elevated growth hormone (GH), low IGF-I levels and growth restriction. Non-classical/mild-moderate GHI is an emerging entity which is poorly characterised, and, in many subjects, the underlying cause is unclear. Heterozygous dominant negative (DN) variants located in the intracellular/transmembrane domain of the GH receptor (GHR) cause a ‘non-classical’ GHI phenotype.<p class="abst...

Primary hyperparathyroidism in a pediatric patient with tuberous sclerosis

Lucia Feller Ana , Mariana Aziz , Victor Ayarzabal , Ciaccio Marta , Gisela Viterbo

Introduction: Tuberous sclerosis (TS) is a rare, autosomal dominant, multisystem disease with a frequency of 1:6,000-10,000. It is caused by variants in the genes encoding hamartin (TSC 1) and tuberin (TSC 2) that normally act as inhibitors of the mTOR signaling cascade that regulates cell proliferation and migration, angiogenesis, and cell metabolism. The most frequent clinical presentation includes hypochromic macules, angiofibromas, hamartomas in the centra...
