Background: Diabetic dyslipidaemia is characterized by high triglycerides (TG), low HDL cholesterol (HDL-C) and the presence of small, dense LDL. The UK National Paediatric Diabetes Audit (NPDA) 2013/14 reported that 16.1% of children and young people (CYP) with type 1 diabetes mellitus (T1DM) have a total cholesterol (TC) of ≥ 5 mmol/l. TG, LDL and TC-HDL-C were not reported in the NPDA. The significantly high prevalence of hypercholesterolemia in CYP with T1DM is conce...

Background: Data on metabolic effects of gonadotropin-releasing hormone agonist (GnRHa) therapy are still controversial.Objective and hypotheses: To longitudinally evaluate the effect of GnRHa therapy on BMI, glycaemic metabolism and lipid profile in children affected by idiopathic central precocious puberty (CPP).Method: This longitudinal retrospective study included data from 42 children (7.70±0.80 years, 2 males) affected b...

Background: LDL cholesterol (LDL-C) levels can be high in familial hypercholesterolemia or other dyslipidemia, and the elevated levels are often found in the pediatric setting.Objective: To create a pediatric reference using data of a prospective birth cohort study at our hospital (Seiiku Cohort for Children and Mothers) and to examine its association with possible predisposing factors.Resu...

Beckwith Wiedemann syndrome (BWS) is a rare overgrowth disorder characterised by macroglossia, exomphalos, lateralised overgrowth, organomegaly, hyperinsulinism, and an increased risk of embryonic tumor during early life. In about 80% of BWS cases, molecular defects are identified at the imprinted 11p15.5 region which contains the IGF2 and the CDKN1C genes (most patients show methylation defects at either imprinting control region IC1 or IC2, or paternal unip...

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...

Background: 17β-Hydroxysteroid Dehydrogenase3 (17b-HSD3) deficiency is a rare autosomal recessive disorder, caused by a mutation of the HSD17B3 gene. The phenotypic spectrum ranges from normal-appearing female external genitalia to microphallus with hypospadias and variable degrees of genital ambiguity. 17b-HSD3 deficiency phenotype is variable, leading to misdiagnosis especially with partial androgen insensitivity syndrome and 5alfa reductase deficiency.<p c...

NMDA (N-Methyl-D-aspartic acid) receptors have been shown to control the timing of sexual maturation in laboratory animals. Therefore, variants in genes impacting NMDA receptor signaling might be predicted to affect human puberty. We studied an extended family with extremely delayed puberty (menarche at 16.5 - 18 years for female family members and pubertal onset at 16 years for male family members). Exome sequencing revealed a rare missense variant (F900V) in DLG2, w...

Background: Congenital hypothyroidism(CH) is the most common neonatal endocrinological disorder in the world. Although most of the CH is sporadic, some genetic defects are responsible from the etiology. The aim of this study was to determine the genetic and etiological factors of CH.Methods: 49 patients(female;n=24), from 24 families were included in the study. The data, collected retrospectively, consisted ...

Background: Leydig Cell Hypoplasia (LCH) is a very rare autosomal recessive condition that is manifested by a wide spectrum of phenotypes, ranging from completely female external genitalia to male genitalia. Long-term outcome in these patients is unclear.Objectives: To assess sex assignment, clinical characteristics and long-term outcome of 46,XY LCH cases.Patients and Methods: Thr...

Background: Rokineticin receptors (PROKR1 and PROKR2) belong to the family of G protein-coupled receptors. Bi-or mono allelic mutations in PROKR2 gene have been identified in Kallmann syndrome which is characterized by hypogonadotropic hypogonadism and anosmia/hyposmia. Recently, PROKR2 mutations were reported in patients with multiple pituitary hormone (MPHD) and growth hormone deficiencies (GHD), suggesting a potential role for the PROK2 p...
