Spondyloocular syndrome (OMIM 605822) is an autosomal recessive disorder characterized by skeletal complaints (osteoporosis, platyspondyly, multiple bone fractures), hearing loss and ocular symptoms (cataracts, retinal detachment). XYLT2 gene (OMIM 608125) mutation encoding xylosyltransferase II enzyme which is responsible from the first step of proteoglycan assembly is responsible for the pathogenesis. Phenotypical variability is associated with varying genetic expre...

Objective: Hereditary hypophosphatemic rickets is a rare renal phosphate wasting disorder causing burden on pediatric patients despite conventional treatment of phosphate and calcitriol. The aim of this study is to analyze genetic and clinical variability of children with X-linked hypophosphatemic rickets (XLHR), focusing on short term, long term and pubertal impact of conventional treatment. Design: Retrospective cohort studyMet...

Introduction: Autoimmune polyendocrinopathy type 1 (APECED) is an autosomal recessive disease caused by loss of function mutations of autoimmune regulatory (AIRE) gene. Characteristically, early onset ectodermal dysplasia, mucocutaneus candidiasis is followed by hypoparathyroidism and primary adrenal insufficiency usually within the first two decades. Although clinical features may be variable, recently, it is suggested that population characteristics and natu...

Calcineurin inhibitors (CNIs) are widely used in pediatric transplantation for prevention of graft rejection, prophylaxis and treatment of graft versus host disease. Though hyperkalemia is a common adverse effect (10-45%), alterations in renin-angiotensin-aldosterone system in CNI-induced hyperkalemia are not well elucidated. Consequently, CNIs vital to transplantation are usually switched. Here, we describe two cases with CNI-induced hyperkalemia due to hyporeninemic hypoaldo...
