Background: McCune Albright syndrome (MAS) is defined by the classic triad of precocious puberty, fibrous dysplasia of bone and café au lait skin pigmentation. However, the clinical spectrum is often more variable due to mosaic distribution of the postzygotic GNAS-mutation. Hypercortisolism occurs in a minority (5%) of patients. It is most frequently caused by nodular adrenal hyperplasia and can be life-threatening. Decisions on whether clinical management should be conse...

Turner syndrome (TS) affects 25-50 per 100,000 females and can involve multiple organs through all stages of life, necessitating a multidisciplinary approach to care. Numerous important advances have been noted during recent years. These advances cover all specialty fields involved in the care of girls and women with TS. This new international guideline is based on an international effort with emphasis on 1) diagnostic and genetic issues, 2) growth and development during child...

Background: Type 2 diabetes mellitus (T2DM) is a chronic and disabling disease affecting increasing numbers of adolescents. Conventional medical therapy presents unique challenges and seldom stalls progression.Objective and hypotheses: The objective of this presentation is to discuss the findings of contemporary, controlled, and prospective trials of surgical therapy for adult T2DM, which demonstrate dramatic early glycemic control, improvement in cardio...

Turner syndrome is a condition in females missing a sex chromosome (45,X) or parts of the second sex chromosome. It is considered a rare condition and associated with a range of characteristics, such as short stature, ovarian dysgenesis, delayed puberty and infertility, congenital malformations of the heart, endocrine disorders, including a range of autoimmune conditions and type 2 diabetes. Morbidity and mortality is clearly increased compared with the background population a...

Background: Generalized lymphatic anomaly (GLA) is a rare congenital disorder characterized by aggressive proliferation of dilated lymphatic vessels. The etiology of GLA is poorly understood.Objective and hypotheses: To identify the underlying genetic basis for GLA.Method: Exome sequencing (ES) was performed in two families, including a multigenerational family (family-1) with six affected members. RNA-seq was performed on skin bio...

Background: Prenatal androgen exposure can lead to variable virilization of external female genitalia. The lack of a consensus definition of clitoromegaly and the limited data available on normal steroid levels in female neonates makes its diagnosis difficult.Objective and hypotheses: The aims of this study were (i) to define reference sizes for external female genitalia in term and preterm neonates as a function of gestational age and birth weight; and ...

Background: Transient neonatal diabetes mellitus (TNDM) is a rare form of diabetes mellitus that presents within the first 6 months of life with remission in infancy or early childhood. TNDM is mainly caused by anomalies in the imprinted region on chromosome 6q24; however, recently, mutations in the ABCC8 gene, which encodes sulfonylurea receptor 1, have also been implicated in TNDM.Objective and hypotheses: To describe clinical features and lab...

Background: Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare and life-threatening primary immunodeficiency characterized by widespread autoimmunity. Mutations in the FOXP3 gene have been identified as the cause for IPEX syndrome.Objective and hypotheses: To describe clinical characteristics and genetic finding in the first Vietnamese patient with mutation of FOXP3 gene.Meth...

Background: Congenital hypothyroidism (CH) affects one in 3000 children at birth. In 65% of cases, CH is due to thyroid dysgenesis (CHDT). For CHDT, there is a family component and therefore genetic. Over the past 20 years, disease-causing mutations in 10 genes have been implicated in CHDT cases (NKX2-1/TTF1, FOXE1/TTF2, NKX2-5, PAX8, GLIS3, NTN1/Netrin-1, JAG1, BOREALIN/CDCA8, TUBB1</...

Background: While the risk for hypoglycemia during acute illness is well described in children with classical congenital adrenal hyperplasia (CAH), there is little evidence for the prevalence of asymptomatic hypoglycemia in CAH. We explored the glucose profile of children with classical CAH by the use of continuous glucose monitoring (CGM).Methods: We conducted an observational study in children aged 1-6 years with a dia...
