Background: Congenital Proopiomelanocortin deficiency (POMC) is a rare autosomal recessive disorder characterized by the association of adrenal insufficiency, early onset obesity, hyperphagia and altered skin & hair pigmentation. POMC is a complex propeptide encoding a range of melanocortin peptides that are released by tissue-specific proteolytic processing. These peptides have important roles in a range of functions such as skin pigmentation and the cont...

Introduction: Mitchell Riley syndrome is a rare autosomal disorder, characterized by severe neonatal diabetes associated with hypoplastic or annular pancreas, duodenal or jejunal atresia, intestinal malrotation, gallbladder hypoplasia or agenesis, and cholestatic disease, less common features were reported such as severe neonatal anemia, hemochromatosis and biliary atresia.Mitchell-Riley syndrome is caused by a mutation in regulatory fac...

Background: Vitamin D dependent rickets type II (VDDR II) is a rare autosomal recessive disorder, inherited due to mutation on vitamin D receptor (VDR) leading to end organ unresponsiveness to vitamin D. It is characterized by an early onset refractory rickets, hypocalcaemia, hypophosphatemia, growth retardation, hyperparathyroidism and elevated circulating levels of 1,25-dihydroxyvitamin D3 which is the hallmark of the disease.Objective and hypotheses: ...

Background: Patients with NNT (Nicotinamide Nucleotide Transhydrogenase) gene mutations, a rare cause of glucocorticoid and mineralocorticoid deficiency. Adrenal Rest Tumor (ART) in females, reported so far only in noncompliant patients with congenital adrenal hyperplasia and elevated ACTH levels, is very rare (<20 cases world-wide). This study characterizes the pathophysiology, the molecular ontogeny and methylation analysis of a unique ART in a female wit...

Background: Mutations in Steroidogenic factor 1 (SF-1; also known as NR5A1), a transcription factor involved in sexual differentiation, steroidogenesis and reproduction, have been associated with mild to severe XY and XX DSDs and adrenal failure. Asplenia and complete XY sex reversal were recently reported in a Palestinian patient homozygous for p.R103Q NR5A1 mutation.Clinical Cases: Five Pales...

Background: PDX-1 gene is involved in the early development of the pancreas and plays a major role in glucose-dependent regulation of insulin gene expression. Defects in this gene cause pancreatic agenesis, which can lead to early-onset insulin-dependent diabetes mellitus (IDDM).Clinical Data: A 1-day-old male newborn, admitted to NICU due to antenatal diagnosis of duodenal atresia, polyhydramnios and IUGR. Laparotomy re...

Objectives: Pseudohypoaldosteronism type 1(PHA 1) is a rare hereditary disorder characterized by resistance to the actions of aldosterone. Two different modes of inheritance with different mechanisms and clinical manifestations have been described, Autosomal recessive that affects the epithelial sodium channel (ENaC),the defect is permanent and affects all aldosterone target organs. Autosomal dominant or sporadic PHA 1, affects the mineralocorticoid receptor i...

Objectives: Sanjad-Sakatti syndrome or hypoparathyroidism-retardation-dysmorphism syndrome (HDRs) is a rare autosomal recessive multisystem disorder characterized by intrauterine and postnatal growth retardation, infantile-onset hypoparathyroidism that can result in severe hypocalcemic seizures, dysmorphic facial features, and developmental delay.Methods: Thirteen unrelated Palestinian infants to a consanguineous Palesti...

Background: Pituitary hormone deficiency combined type 3 (CPHD3; MIM# 221750) is an autosomal recessive combined pituitary hormone deficiency caused by mutations in LHX3, a LIM-homeodomain transcription factor gene which is necessary for the normal pituitary and motorneuron development.Aims: Clinical manifestations of CPHD3 are pituitary dwarfism and might be accompanied by rigid cervical spine leading to limited neck rotation or sensorineural deafness. ...

Background: Short stature is the commonest problem encountered in endocrine clinics. Accuracy in opportunistic measurements is helpful in guiding subsequent management regarding medication doses including growth hormone treatment. Our study aimed to assess the prevalence and factors affecting inaccurate height measurements in different non-Endo clinic visits in our tertiary institute.Methods: A retrospective cohort study...
