The insulin-like growth factor (IGF) system is fundamental for physiological processes such as growth and metabolism. In addition, in the brain it regulates glucose metabolism and neuroprotection. The IGF axis can be altered by nutritional status, but little is known regarding the effects of specific dietary components on this system.Our aim was to examine how high-fat diet (HFD) and low-fat/high sucrose diet (LFHSD) intake affect the central and circula...

Background: IGF1R is a keystone of foetal growth regulation by mediating the effects of both IGF-I and IGF-II. Recently the first clinical cohort of patients carrying an IGF1R defect has been reported from which a clinical score was established for diagnosis. Since no external validation of this score is available we assessed it in a large cohort of patients with identified IGF1R defects. Furthermore we aim at setting-up a functional test to ...

Introduction: The degree of consistency between the findings from next generation sequencing (NGS) and detailed endocrine assessment is unclear in boys with XY DSD.Objectives: Examine the range of endocrine and molecular genetic variation in boys undergoing evaluation for XYDSD.Methods: Boys with XYDSD who were evaluated in Glasgow from 2016 to 2018 were included. Sequence variants...

Introduction: Childhood obesity and insulin resistance (IR) are rising in prevalence, increasing the future adults' cardio-metabolic risk. One of the potential mechanisms behind these alterations is oxidative stress, fruit of increased free radical production and diminished antioxidant defense. Although low plasma vitamin concentrations and oxidative stress have been observed to be associated with obesity in adults and children, their association with IR i...

Introduction: PTEN Hamartoma Tumor Syndrome (PHTS) is a rare disease with dominant inheritance characterized by benign (hamartoma) and malignant tumors (breast, endometrium, thyroid). Mutations in the tumor suppressor gene phosphatase and tensin homologue (PTEN) gene are responsible for the etiology.Objective: In this case report, we present an 11-year-old male who was being monitored due to follicular thyroid cancer, an...

Introduction: An activating mutations in the ABCC8 gene cause both transient and permanent neonatal diabetes mellitus (DM) or MODY 12. In relation to the variant in the ABCC8 gene, patients may also present with either neonatal hyperinsulinism and/or DM later in life. Besides, the same variant can cause different phenotypic features among family members. Response to the sulfonylurea treatment may vary between patients.<...

Introduction: Heterozygous loss-of-function mutations in the glucokinase (GCK) gene cause MODY 2. Conversely, homozygous loss-of-function mutations in the same gene give rise to permanent neonatal diabetes mellitus (DM). Previously, two patients diagnosed with DM in adolescence and had homozygous GCK mutations were reported. Variants in these patients have been shown to exhibit inactivated kinetics that are indistinguishable from neonatal ons...

Introduction: Congenital generalized lipodystrophies (CGL); autosomal recessive disorders characterized by dyslipidemia and almost complete absence of body fat associated with insulin resistance. It develops due to mutations in AGPAT2, BSCL2, CAV1, PTRF, PCYT1A and PPAR, genes.CGL type 4 results from PTRF-CAVIN gene mutation. Unlike classical CGL, myopathy, flat and skeletal muscle hypertrophy, heart rhythm disorders (sudden death) and skeletal abnormalities a...

Introduction: Resistance to thyroid hormone alpha (RTHα) is characterised by tissue-specific hypothyroidism associated with barely normal thyroid function tests. Clinical features include dysmorphic facies, skeletal dysplasia, growth retardation, constipation, dyspraxia and intellectual deficit. Hormonal assessment often shows decreased/low-normal free thyroxine (fT4) and increased/high-normal free triiodothyronine (fT3) concentrations, resulting in a low...

Introduction: Heterozygous inactivating mutations of the CaSR gene (CaSR) generally result in mild, asymptomatic hypercalcemia in the familial hypocalcuric hypercalcemia syndrome. Homozygous inactivating CaSR mutations end up with neonatal severe hyperparathyroidism. Calcimimetics are drugs that interact with the transmembrane part of CaSR and make the receptor more sensitive to calcium. Cinacalcet, a type II calcimimetic, suppresses PTH levels and increases r...
