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: 3β-hydroxysteroid dehydrogenase (3βHSD) deficiency is a rare form of congenital adrenal hyperplasia (CAH) and caused by loss of function mutations in the HSD3B2 gene. In classic form, affected patients have salt wasting early in infancy and may have ambiguous genitalia in both sexes. Herein we report a nonvirilized female patient with classic form of 3βHSD deficiency due to homozygous S218P mutation in the HSD3B2 gene and classic phenylketonuria....

Background: 17 hydroxylase deficiency is a rare form of congenital adrenal hyperplasia resulting from loss-of-function mutations involving the CYP17 gene. It is characterized by decreased production of glucocorticoids and sex steroids and increased synthesis of mineralocorticoid precursors.Objective and hypotheses: We aimed to identify genetic cause of lack of puberty in a girl and the cause of ambiguous genitalia in her sibling. Fourteen-year-o...

Background: Two LIM homeodomain transcription factors, Lhx3 and Lhx4, are critical in the development of the nervous system and pituitary gland in mice. Lhx4 null mice die shortly after birth and have abnormal pituitary gland development. Recently, the first human homozygous LHX4 mutation was described, resulting in congenital hypopituitarism and neonatal death. Heterozygous LHX4 variants have been described and are linked to hypopituitarism but have...

Background: Mutations in genes encoding type 1 procollagen (T1PC) and proteins responsible for posttranslational modifications of the T1PC heterodimer may result in brittle bone disorder osteogenesis imperfecta (OI). FKBP65 is a known chaperone for type I procollagen and encoded by FKBP10. Autosomal-recessively inherited epidermolysis bullosa simplex and moderately severe OI caused by FKBP10 mutation reported in consanguineous Turkish and Mexican families.</p...

Background: Proopiomelanocortin (POMC) deficiency is characterized by severe, early-onset hyperphagic obesity and congenital adrenal insufficiency, the latter secondary to ACTH deficiency.Case: 3.5 years old female patient whose initial diagnosis was neurometabolic disease because of motor mental retardation, ataxia, and bilateral hyperintense lesions in the basal ganglia in magnetic resonance imaging, increased lactate-lipid peak in proton magnetic reso...

Background: Adrenal insufficiency is an important and potentially life-threatening condition, and it is also known as a rare cause of hypercalcaemia.Objective and hypotheses: Resistant hypercalcemia may be associated with hypocortisolism.Method: A 18-day-old male infant was born at 36 weeks by emergency cesarean section for fetal distress and intrauterine growth retardation. He was referred to paediatric endocrinology because of th...

Background: Leprechaunism, also known as Donohue syndrome, is due to a severe congenital insulin-resistance, with prenatal and neonatal growth retardation, typical dysmorphic features, glycaemic dysregulation with hyperinsulinism and hyperandrogenism.Objective and hypotheses: These patients have a poor prognosis with death in the first year of life.Method: We report the case of a newborn (35.4 weeks) with severe fetal growth restri...

Background: Ovarianleucodystrophies are one of the rarest leucodystrophies associated with primary ovarian failure. Patients may present with variable disease manifestations such as neurologic, psychiatric or ovarian failure. Disease onset may occur in infancy, adolescence or adulthood caused by mutation in the eukaryotic initiation factor 2B (eIF2B) which has a poor prognosis.Objective and hypotheses: Seventeen-year-old girl was brought with tremor, gai...

Introduction: Neonatal diabetes mellitus (NDM) is a monogenic form of diabetes that occurs in the first 6 months of age. It is a rare condition occurring in only one in 100 000–300 000 live births. Clinically, NDM subgroups include transient (TNDM) and permanent NDM (PNDM). TNDM is most frequently caused by abnormalities in the imprinted region of chromosome 6q24.Case Report: A 18-day-old male was referred from another clinic due to diabetic ketoaci...
