Introduction: Costello syndrome is a rare RASopathy that is associated with such characteristics as prenatal overgrowth, postnatal growth retardation, mental-motor retardation, coarse face appearance, loose skin on the neck, hands and feet, cardiovascular abnormalities, deep palmar and plantar lines and a predisposition to various types of cancer. Several endocrine disorders, including growth hormone deficiency, adrenal failure, glucose intolerance, hyperprolactinemia and hypo...

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...

Background: Triple A syndrome is a rare autosomal recessive disorder characterized by adrenal failure, alacrima, achalasia, and a variety of neurological features. In 70% of the families it is caused by mutations in the AAAS gene. Linkage analyses indicated genetic heterogeneity and exome sequencing revealed two further genes causing triple A-like syndromes.Objective and hypotheses: To summarise the genotypes and phenotypes of classic triple A s...

Objective: The first line of treatment for Cushing`s disease (CD) is transsphenoidal surgery (TSS), whose effectiveness range is from 70 to 90%. If surgical treatment is unsuccessful or recurrence appears, radiation treatment (RT) is the next therapeutic option, which effectiveness range is also 90%, but the hypopituitarism rate as side effect of treatment is higher.Aim: Analysis of recurrence rates of CD and side ...

Background: Puberty is a dynamic period of physical growth. Genetic factors, increasing prevalence of adiposity, environmental factors and the widespread presence of endocrine-disrupting chemicals are suspected to contribute to the trend of earlier pubertal onset.Method: The study group consists of 32 girls diagnosed with central puberty precocious. The eating habits and physical activity status were evaluated with a detailed questionnaire. Daily calorie...

Objectives: Familial hypocalcemia is a rare autosomal dominant disease characterized by hypercalciuric hypocalcemia. The disorder is caused by heterozygous mutation in the CASR gene that encode a calcium-sensing receptor in parathyroid glands and kidney tubules.Clinical case: The boy was born at term from non-consanguineous parents with normal length and weight. On the second day of life he was admitted to an intensive care department with convu...

Background: Androgen insensitivity syndrome (AIS) is the most common cause of 46,XY sexual differentiation disorders. Clinical presentation is variable among cases with a range from a complete female to male external genitalia. There is a weak correlation between genotype and phenotype.Aım: Our aim is to report clinical and molecular characteristics of siblings with AIS.Patients and methods: Two siblings newborns with ambiguou...

Background: Neurokinin B and kisspeptin appear to play main roles in puberty.Aims and objectives: The aim of the present study was to investigate the diagnostic role of kisspeptin and neurokinin B in central precocious puberty (CPP) and premature thelarche (PT).Methods: The girls who presented with breast development (between 5 and 8 years) were included in the study. All cases underwent bone age (BA) assesment. Basal serum FSH, LH...

Background: False-negative results can occur an extremely high level of substrate at the assay system. This is called the ‘high-dose hook effect’.Case presentation: 14 year-old female patient was referred with short stature, amenorea and hirsutism. Height, weight and blood pressure were 140.5 cm (SDS:−3.5), 43.4 kg (SDS:−1.6) and 120/80 mmHg. She had stage 1 Tanner breast, stage 5 pubic hair and hirsutism (mFG scale: 28) with androi...

Background: Adrenal hypoplasia congenital associated with DAX-1 (NROB1) gene mutations is a rare cause of primary adrenal insufficiency in male. It can be presented as a part of Xp21 contiguous gene deletion syndrome which characterized by complex glycerol kinase deficiency (GK), adrenal hypoplasia congenital (NROB1), intellectual disability (IL1RAPL1) and/or Duchenne muscular dystrophy (DMD).Case report: We report a 6-month-old male infant, which presen...
