Obesity—defined as excess fat mass which impacts on physical health—is a complex and multifactorial disease where numerous environmental factors (overeating and/or reduced physical activity) act in concert with genetic factors. Understanding molecular mechanisms of obesity has rapidly improved in recent years due to the development of faster, more specific genetic screening tools (1). Rare genetic obesities are distinguished from more-common polygenic obesities where...

Background: Hydrometrocolpos is a condition resulting in distension of the vagina and uterus due to accumulation of secretions (other than blood), caused by increased oestrogenic stimulation and vaginal outflow obstruction. The incidence in term neonates is 0.00014-0.001%. The condition presents at extremes of childhood, at birth when maternal circulating hormones are raised and at menarche when oestrogen production commences. Pseudohypoaldosteronism (PHA)...

Introduction: X-linked hypophosphatemic rickets (XHR) is the most common form of hereditary rickets, with an estimated incidence of 1: 20.000 individuals. The main characteristic of the disease is excessive renal phosphate loss, which leads to hypophosphatemia with high phosphaturia and defective bone mineralization.XHR results from mutations in the in the PHEX gene (Phosphate Regulatory Gene with Homology for Endopeptidases located on t...

Background: Silver Russell Syndrome(SRS) is a rare heterogeneous genetic disorder, which is mostly known because of its prenatal and postnatal growth retardation. Patients with Russell silver syndrome have syndromic facial appearance as well as some other common clinical features. The last guideline for diagnosis of SRS is Netchine– Harbison clinical scoring system that is clinical scoring system and followed by molecular evaluation.<p class="abstext"...

Background: Hypophosphatasia (HPP) is a rare metabolic bone disease caused by loss-of-function mutations in the gene ALPL encoding the tissue nonspecific alkaline phosphatase. HPP is associated with significant morbidity and mortality in pediatric patients, with high rates as high as %100 in perinatal-onset HPP. Serum alkaline phosphatase (ALP) activity is markedly reduced, which leads to increased serum/urine phosphoethanolamine (PEA), pyridoxal-5’phosphate (PLP). Asfota...

Background: Recently congenital hypothyroidism (CH) is increased,particularly mild forms. Current guidelines recommend initial levothyroxine (LT4) dose of 10–15 mcg/kg per day as soon as possible, if diagnosis is confirmed by serum test, even if FT4 concentration is normal and venous TSH concentration is >20 microUI/ml.Objective and hypotheses: The aim of our study was to evaluate the initial LT4 dose in newborn with congenital hypothyroidism, n...

Introduction: Rapid-onset obesity with hypoventilation, hypothalamic dysfunction and autonomic dysregulation (ROHHAD) is a rare syndrome that presents during early childhood and is associated with high morbidity and mortality. 40-50% of patients have neural crest tumours, most commonly ganglioneuromas or ganglio-neuroblastomas denoted by the suffix ROHHAD(NET) in a subset of patients. Currently, there is no specific diagnostic biomarker available and diagnosis...

Prader-Willi syndrome (PWS), a multisystem disorder, results of the absence of expression of paternal genes from chromosome 15q11.2-q13; it occurs with the prevalence of 1/10000-1/30000 in different populations. In real clinical practice PWS still remains a challenge for doctors, especially in resource-limited settings. We describe clinical course in 10 pediatric PWS patients (3M; 7F) aged 7,4±3,3 years (1,7&div;12,3), all have microdeletion of paternally inherited 15q11....

Cafe au-lait skin macules, Cushing syndrome (CS), hyperthyroidism, liver and cardiac dysfunction have been described as presenting features of neonatal McCune Albright Syndrome (MAS). Despite being defined, neonatal diabetes mellitus due to hypercortisolism is a rare presenting feature. Outcome of patients presenting in neonatal period is usually unfavorable, tthough spontaneous resolution of hypercortisolism have been reported. Newborn girl was born at 38 weeks of gestation v...

Background: Adenosine deaminase (ADA) deficiency is a systemic metabolic disease that primarily affects the immune system and lymphocyte development, causing a severe combined immunodeficiency (ADA-SCID). However, the accumulation of toxic metabolites occurs in other organs and systems. Since most ADA-SCID patients undergo definitive treatment with Gene Therapy (GT) or allogeneic haematopoietic stem cell transplantation (HSCT), preceded by conditioning (either...
