Introduction: APECED Syndrome; is a rare, autosomal recessive disease caused by mutations in the autoimmun regulatuar AIRE gene on the chromosome 21. Although classical triad is mucocutaneous candidiasis, hypoparathyroidism and adrenal insufficiency; endocrine / non-endocrine involvement may also be seen. Possible involvement should be evaluated without any clinical signs. We report a case of APECED syndrome with autoimmune hypophysitis secondary to growth hor...

Introduction: Autoimmune polyglandular syndrome type 1 (OPS1) is characterized by chronic mucocutaneous candidiasis, hypoparathyroidism and autoimmune adrenalitis. The mutations in the localized autoimmune regulator gene (AIRE) at 21q22.3 present the etiological cause.Objective: In this case report, two siblings case who were diagnosed with OPS1 with different clinical findings except classic triad were presente...

Introduction: Gain-of-function mutations in KISS1 and KISS1R genes and loss-of-function mutations in the gene encoding the makorin RING-finger protein 3 (MKRN3) expressed only in the paternal allele are the most common genetic reasons of familial central precocious puberty (CPP).Aim: We report a case of familial CPP and a pathogen variant in the MKRN3 gene.<stron...

Introduction: 17β-hydroxysteroid dehydrogenase type 3 (17βHSD3) enzyme deficiency is a rare cause of 46 XY disorder of sexual development. It is inherited autosomal recessively and clinical phenotype is highly heterogeneous and depends on the mutation severity. Conversion of androstenedione to testosterone deteriorates due to lack of enzyme.Objective: In this case report, we present a case who was born en...

Puberty is a physical, hormonal and psychosocial transition from childhood to adolescence. Precocious puberty (PP) is the beginning of secondary sexual characteristics before eight years of age in girls. The most common type is known as “central precocious puberty (CPP)”. CPP occurs due to early activation of the hypothalamus-pituitary-gonad (HPG) axis. Although the real trigger for idiopathic CPP is unknown, it has been proposed that it may be caused by the interact...

Background: The current diagnostic criteria for Prader–Willi syndrome (PWS) although widely accepted, is challenging to be implemented in Chinese population.Objective and hypotheses: The present study collected PWS cases from 12 centres across China. By analysing the clinical manifestation during early infancy, we aimed to provide data for clinical characteristics, screening strategy and effect of GH treatment in Chinese PWS patients.<p class="a...

Introduction: The etiology of hyperandrogenism is diverse and diagnosis is based on history, clinical findings, reliable measurement of steroid hormones and genetic analyzes. In the electrochemiluminescence immunoassay (ECLIA) method, the presence of various endogenous compounds and the use of certain pharmaceutical agents may cause interference in results, on the other hand liquid chromatography-mass spectrometry (LC-MS/MS) method allows measurement of 17 adr...

Introduction: Anti-thyroid arthritis syndrome (AAS) is a rare complication that may occur in patients treated with anti-thyroid drugs. Presentation is variable and may include myalgia, arthralgia, skin rash, high fever, and polyarthritis. Herein, we present a girl diagnosed with AAS. Case report: A 9-year-old girl was admitted to emergency complaining of fever and arthralgia. She was the second child of non-consanguineous healthy parents. She had been d...

Background: Osteogenesis imperfecta (OI) is a genetic disorder characterized by diffuse osteoporosis, recurrent fractures, and resulting deformities. Bruck syndrome (BS) is a rare autosomal recessive disease that manifests with many symptoms of OI. In addition to the deficiency of type I collagen in OI, congenital joint contractures also occur in BS. BS is caused by mutations of FKBP10 (BS type 1) and PLOD2 (BS type 2) genes encoding the chaperone-collagen com...

Introduction: SHOX deficiency is the most common cause of monogenic short stature and results in short stature with a highly variable phenotype. In this study, we aimed to detect SHOX gene pathologies in patients who applied to the pediatric endocrine outpatient clinic with short stature and who were found to have Madelung deformity on hand-wrist radiography, and to evaluate the clinical, laboratory features and responses to growth hormone (GH) treatment.<...
