Background: Genetic factors play an important key role in regulating the timing of puberty. The premature activation of pulsatile release of gonadotropin-releasing hormone(GnRH) before 8 and 9 years of age in girls and boys causes central precocious puberty(CPP). Pathogenic variants in DLK1 are associated with isolated familial CPP. Here, we report three siblings with a diagnosis of CPP with novel variant in DLK1.Case Report:</st...

Objective: The incidence of congenital hypothyroidism (CH) has increased worldwide. Lowering cut-off in screening programs has led to an increase in the rate of transient CH. We aimed to evaluate the rates of permanent and transient CH in cases referred from the screening program and to investigate the clinical and laboratory factors to predict the transient CH.Methods: 109 cases referred from the screening program to ou...

Introduction: Bardet-Biedl syndrome is a rare autosomal recessive disease, characterized by rod-cone dystrophy, truncal obesity, left foot polydactyly, cognitive impairment, male hypogonadotrophic hypogonadism, female genitourinary malformations, and renal abnormalities. The authors present 3 cases of Bardet-Biedl syndrome diagnosed during pediatric age.Case description: Case1: A 3-year-old girl with a f...

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...

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...
