Kyphosis is a common spinal disorder affecting up to 8.3% of the population, and associated with significant morbidity. Familial and twin studies have implicated a genetic involvement. However, the causative genes have not been identified. Studies investigating the underlying molecular mechanisms are hampered by genetic heterogeneity, small families and variable modes of inheritance displayed by different kindreds. To overcome these limitations, we investigated 12 week old pro...

Kyphosis and scoliosis are common spinal disorders that lead to significant morbidity in childhood, adolescence and adulthood. Familial and twin studies have implicated a genetic involvement, although the causative genes remain to be identified. To facilitate these studies, we investigated 12-week-old progeny of mice treated with the chemical mutagen N-ethyl-N-nitrosourea (ENU) using phenotypic assessments that included dysmorphology, radiography and dual-energy ...

Introduction: Adrenal venous sampling (AVS) is the criterion standard method of lateralisation in primary aldosteronism (PA). Despite this pivotal role, there is limited consensus and significant variability between centres related to many of the technical aspects of AVS. In this study, we sought to address whether variations in two different technical aspects of AVS altered parameters and interpretation, namely: 1. Peripheral sample site 2. Method of adrenal vein (AV) venesec...

Renal calcification (nephrocalcinosis), which has a multi-factorial etiology involving environmental and genetic determinants, affects ~8% of adults by 70 years. Nephrocalcinosis may occur as a familial disorder in ~65% of patients, and in 70% of patients, nephrocalcinosis may be associated with endocrine and metabolic disorders that include primary hyperparathyroidism, renal tubular acidosis, hypercalciuria, cystinuria, and hyperoxaluria. Investigations of families with hered...

Background: FOP is an ultra-rare, severely disabling genetic disorder characterised by cumulative heterotopic ossification (HO), often preceded by episodic flare-ups, leading to physical disability and early death. Initial misdiagnosis can occur in ~90% of individuals leading to unnecessary, often harmful interventions. FOP is diagnosed and managed by multiple specialists, including endocrinologists.Objective: A prospective, 36-month, global natural...

Cushing’s syndrome, which is characterised by excessive circulating glucocorticoid (GC) concentrations, may be due to ACTH-dependent or -independent causes that include anterior pituitary and adrenal cortical tumours, respectively. In the course of our phenotype-driven screens of mouse mutants induced by the chemical mutagen N-ethyl-N-nitrosourea (ENU), we observed a mutant mouse with obesity, hyperglycaemia and low bone mineral density, features that ar...
