Background: Sitosterolaemia, or phytosterolaemia, is a disorder of increased plant sterol levels in the body leading to a variable presentation including hypercholesteremia, xanthoma, atherosclerosis and haematological manifestations. Although considered rare, the prevalence is likely underestimated due to the variable phenotype. It is caused by recessively inherited mutations in ABCG5 or ABCG8 which encode the sterol efflux transporters in the gut. Hyperchole...

Background: Pseudohypoparathyroidism (PHP) is a condition primarily caused by impaired hormonal signaling through the stimulatory G protein (G2 alpha) for the activation of adenyl cyclase, which is coupled to G protein receptors(1). This occurs due to the molecular defects in the receptors related to the alpha subunit. (1–3). The condition results in resistance to Parathyroid hormone (PTH) and other hormones. Less than 60 cases have been reported worldwi...

Background: Prader-Willi syndrome (PWS) is a rare genetic obesity syndrome associated with relative growth hormone deficiency. Scoliosis is a known association of both PWS and growth hormone therapy (GH), although its role in causation remains uncertain. In the literature, short-term and long-term data revealed no adverse effects of GH on scoliosis. As the metabolic and clinical benefit of growth hormone therapy is established in the management of PWS, it is d...
