Pseudohypoparathyroidism (PHP) is a disease of rare frequency. There are five subtypes with each having different phenotypes and blood laboratory test results, which depend on gene mutation and hereditary styles. Among them, the most common type is PHP Ia which inherits maternal gene mutation and expresses Albright’s hereditary osteodystrophy (AHO) appearance, hypocalcemia, hyperphosphatemia and serum parathyroid hormone elevation. Another type, pseudo-pseudohypoparathyro...

Background and hypothesis: Mitochondrial disorders are multisystemic conditions associated with sensorineural hearing loss, encephalomyopathy, lactic acidosis, and non-autoimmune diabetes. The majority of molecular etiologies involve mutations in the genes encoding the oxidative phosphorylation system's components. Superoxide generation is significantly increased and causes oxidative damage in the affected tissues in these disorders. The establishment of ...

Copy-number variation (CNV) is a kind of malfunction of DNA polymerase to produce extra genetic material which leads to more number of repeats in genes. CNVs have been associated with different clinical phenotypes, such as learning disabilities, short stature, and intellectual disability. The chromosomal microarray analysis is an effective diagnostic method for identifying new CNVs and understanding their clinical effects. In this case report, a variation that has not been rep...

Background and aim: Epidemiologic studies have been shown that obesity increases the risk of renal disease and it impact on prognosis. In this study, we aimed to investigate both glomerular and tubular involvement in asymptomatic obese children and to investigate the association of metabolic-anthropometric parameters with renal parameters.Material-method: Children with BMI ≥95th percentile and diagnosed as primary obesity (n=43) were inclu...

Background: Wolcott–Rallison syndrome (WRS) is an autosomal recessive, multi-system disorder with early onset diabetes in infancy. It is associated with clinical features that show variability between WRS cases. Clinical data are still scarce.Patient data: A 9 year old girl followed-up due to diabetes and growth failure since 2 months of age from another centre presented with ketoacidosis and multi-organ failure. After resolution of her decompansate...

Background: HVDRR is characterised by hypocalcaemia, secondary hyperparathyroidism and severe early-onset rickets in infancy and is diagnosed easily especially associated with alopecia.Objective and hypotheses: Successful treatment requires reversal of hypocalcaemia and secondary hyperparathyroidism and is usually failed by high dose calcitriol but sometimes accomplished by administration of high doses calcium. Some patients need enteral or parenteral co...

Background: Thyroid hormone resistance (THR) is an autosomal dominant, rare syndrome and result of the reduction sensitivity of target tissues to thyroid hormone. There is usually normal or slightly elevated TSH concentration with increase in serum fT3 and fT4 concentrations. The most common cause of resistance to thyroid hormone (RTH) is heterozygous thyroid hormone β (THR β) gene mutations. THR is defined by Refetoff et al. at 1967. THR mutati...

Background: Laron syndrome, which is characterised with GH insensitivity, is caused by mutations of GH receptor (GHR). GHR, consisting of nine exons, is located on 5th chromosome. Typical findings of this syndrome are immature facial appearance, prominent forehead and eyes, depressed nasal bridge, low IGF1 and IGFBP3 levels which do not increase with IGF-generation test.Case report: A 4-year and 3-month old boy was admitted because of growth retardation....

Background: Experience with oral desamino-D-arginine-8-vasopressin lyophilisate (OLD) for central diabetes insipidus (CDI) in children with CNS malformations is limited.Objective and hypotheses: We aimed to assess the efficacy of oral use of OLD in children with CDI.Methods: Clinical, laboratory, and imaging characteristics of twenty-five children with CDI treated with OLD were eva...

Context: Deficiency of 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) causes a very rare form of congenital adrenal hyperplasia (CAH) known as 3βHSD2 deficiency, which is a consequence of biallelic HSD3B2 gene defects. The estimated prevalence is less than 1/1,000,000 live births. Knowledge of comprehensive steroid metabolome patterns in 3βHSD2 deficiency is scarce.Objective: We aimed...
