Background: Vitamin D Dependent Rickets Type IA(VDDR1a) is an autosomal recessive disorder characterized by defects in the biosynthesis of its active form 1,25 dihydroxyvitamin D due to the mutations in the CYP27B1 gene encoding for the enzyme 1α-hydroxylase.Objective and hypotheses: To evaluatethe clinical characteristics, molecular genetics aetiology and long-term outcome of a large nationwide cohort of VDDR-Ia f...

Background: Cystic fibrosis is an autosomal recessive genetic disorder affecting typically the lungs, the pancreas, the gastrointestinal tract and tissues that produce mucus secretion, such as sweat glands. Impaired glucose tolerance and cystic fibrosis-related diabetes are the most common complications of cystic fibrosis. Cystic fibrosis-related diabetes is another type of diabetes mellitus and carries some of the characteristics of type1 and type2 diabetes.<p class="abst...

Background: Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH) is characterized by utero-vaginal atresia in patients with a normal female phenotype and 46, XX karyotype. Various anomalies may accompany MRKH. The number of cases with accompanying hyperandrogenemia is limited.Case presentation: We describe a combination of Mullerian agenesis and hyperandrogenemia (total testosterone level 0.85 ng/ml) in a patient presenting with primary amenorrhea and mild hir...

Osteogenesis imperfecta is a hereditary connective tissue disease developing based on the structure or synthesis impairment of type 1 collagen and proceeding with diffuse osteoporosis, fragility, fractures and deformities in bones. Bone mineral density can be at normal or even high levels particularly especially in type I and XIII. Here, a 13 year-old boy diagnosed as osteogenesis imperfecta with normal bone mineral density was presented and treatment results were shared. A 13...

Introduction: Vitamin D resistant rickets type II (VDDR-II) is a disease with a difficult treatment developed as a result of mutations in VDR gene. Despite high dose active vitamin D and oral calcium treatments, sufficient recovery cannot be achieved mostly. Successful results with intravenous calcium infusion that is an alternative treatment have been reported; however, serious restrictions and complications such as hospitalization, catheter infection, thrombosis, skin necros...

Introduction: It has been suggested that adipokines found in breast milk and may be effective in early growth of infants.Purpose: It was aimed to evaluate the relationship between total ghrelin (TGh) and nesfatin-1 levels in breast milk with anthropometric measurements in the first 4 months of life in infants with small for gestation age (SGA) showing fast growth pattern.Method: A total of 20 SGA and 20 control infants with appropr...

Introduction: BMI is claimed to be unreliable in the determination of body fat rate and cardiometabolic risk. Troublesome and reproducibility low measurements like waist circumference, waist circumference/height rate are used in the evaluation of cardiometabolic risk. Triponderal mass index (TMI; weight/height3), however, is suggested to be superior BMI in determining body fat rate and obesity.Purpose: In this study TMI’s relationship wit...

Background: Swyer syndrome (46,XY pure gonadal dysgenesis) is a rare disorder, which is characterized by female phenotype, female internal genitalia and fibrotic and primitive gonads. Classically, breast development and menstruation are absent due to hypergonadotropic hypogonadism.Objective and hypotheses: To our knowledge, three cases of Swyer syndrome with spontaneous breast development have been reported so far. In these reports, breast development wa...

Background: STAT5B deficiency is characterized by severe postnatal growth failure, low IGF1, elevated levels of GH and prolactin, and immunodeficiency. To date, only ten patients with seven different mutations have been described.Objective and hypotheses: Describe clinical characteristics of a novel homozygous frameshift mutation in STAT5B.Results: A 17-year-old female was referred for proportionate short stature and prima...

Background: Partial androgen insensitivity syndrome (PAIS) typically presents with micropenis, penoscrotal hypospadias, bifid scrotum with descending or undescending testes and gynecomastia. It is x-linked recessive disease resulting from mutations in androgen receptor (AR) gene.Objective and hypothesis: To present clinical characteristics of a novel mutation in the AR gene in an adolescent boy with PAIS who presented with gynecomastia ...
