Introduction: The phosphatase and tensin homolog (PTEN) hamartoma tumour syndrome (PHTS) groups related multi-system genetic disorders linked to germline mutations in the PTEN gene. There is an increased risk of thyroid cancer in PHTS, with some cases arising in childhood. Annual surveillance for thyroid cancer by ultrasound is recommended.Case report: A 15 year old female was referred to Paediatric Endocrinology by Clinical Genetics fo...

Background: Mutations in BRAF are a rare cause of cardiofaciocutaneous syndrome (CFC). Recently, BRAF mutations have been reported in papillary craniopharyngiomas, but have not been described in patients with other hypothalamo-pituitary abnormalities. We describe three patients with CFC and septo-optic dysplasia (SOD) associated with heterozygous BRAF mutations.Cases: Patients presented in childhood with clinical features of ge...

Introduction: We report two siblings presenting with pre-pubertal gynaecomastia and macro-orchidism, who were later diagnosed with Peutz-Jeghers Syndrome (PJS) secondary to a STK11 gene variant. Importantly neither child fulfilled the clinical criteria for diagnosis at presentation, with no muco-cutaneous pigmentation nor gastrointestinal symptoms.Case report: Sibling 1 was referred to Paediatric Endocrinology aged 4 years with ...

Background: There is increasing recognition that the in utero environment might influence obesity risk.Objective and Hypotheses: We explored the hypothesis that smoking and alcohol consumption in pregnancy are associated with offspring body composition using the Southampton Women’s Survey mother-offspring birth cohort study.Method: At 34 weeks’ gestation, maternal smoking and any alcohol intake in the preceding 1...

Background: Recent studies using data from the International Congenital Adrenal Hyperplasia (CAH) Registry (www.i-cah.org) (1), have provided valuable insight into the determinants of reported acute adrenal insufficiency (AI) related adverse events, demonstrating that the I-CAH Registry can be used as a tool to create clinical benchmarks in CAH care.Methods: Care quality reports were created for 32 centres who participat...

Background: Neonatal vitamin D deficiency (VDD) can result in symptomatic hypocalcemia, seizures and cardiomyopathy and has been associated with reduced bone mineralization in childhood, but is potentially preventable with antenatal cholecalciferol supplementation. Single nucleotide polymorphisms (SNP) in the vitamin D metabolism pathway are associated with serum 25-hydroxyvitamin D [25(OH)D] in adulthood. We assessed whether maternal and/or offspring SNPs in ...

Background: In later life, osteoporosis and poor cognitive function often co-exist. This has commonly been attributed to post-menopausal estrogen loss, but there is increasing recognition of cross-talk between the brain and bone. For example, in animal models, bone derived osteocalcin has positive associations with brain volume and cognitive function whilst brain-derived neurotransmitters appear to influence bone mass. Despite this, a common early life origin ...

Introduction: Congenital adrenal hyperplasia (CAH) is associated with long-term health problems. However, little is known about co-morbidities and their onset in children and young persons (CYP).Objective: To establish the health status of CYP with CAH across the United Kingdom.Methods: A multi-centre prospective study recruited 102 patients with 21-hydroxylase deficiency targeting...

Growth hormone (GH) is commonly used during childhood to treat short stature in Silver-Russell syndrome (SRS), but final height and long-term body mass index (BMI) data are limited.Objective: To evaluate height and BMI in older individuals with molecularly confirmed SRS and compare those previously treated with GH to those untreated.Methods: Growth data on individuals aged ≥13 years with SRS were evaluated from UK, French and...

Introduction: Patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) have specific plasma and urinary steroid patterns, with 11-oxygenatedC19 steroids established as key adrenal-specific androgens. Monitoring glucocorticoid (GC) replacement remains a challenge in the absence of reliable biomarkers.Aim: To reassess the urinary steroid profile of children with CAH in relation to plasma ...
