Introduction: In medical practice, sex assignment at birth depends primarily on the appearance of the external genitalia, which development begins as early as the fetal period and is largely dependent on dihydrotestosterone (DHT). Any discordance between the chromosomal, gonadal or anatomical sexes can lead to a disorder of sex development (DSD). 5 alpha-reductase 2 (5aRD2) deficiency is a very uncommon autosomal recessive genetic disorder that falls into the DSD 46 XY group, ...

Introduction: Adequate nutritional status of adolescents is essential for their healthy development, with health repercussions in both short-term and adult life.Objective: To analyze the temporal trends of the BMI of Brazilian adolescents (10 to 19 years old) between 2010 and 2022.Patients and methods: Descriptive ecological study. Data obtained from e-SUS Primary Care. The BMI cat...

Objective: Maturity onset diabetes of the young (MODY)5 is a type of monogenic diabetes. Primary autosomal recessive microcephaly (MCPH)3 is a rare microcephaly caused by depletion of neuronal progenitor cells characterized by mostly normal brain structure, mental retardation, and premature closure of the frontal cranial suture. To report a case of MODY5 combined with MCPH3, in order to increase the clinical attention to this disease.<st...

The changes of the immune reactivity, the production of hormones and the neuroendocrinal regulation of immune homeostasis are the entities closely connected with the puberty. There is evidence for the role of cytokines in securing of intersystemic interaction as well as for the influence of reproductive hormones on the cytokine production. However, the question as to the role of cytokine in the formation of delayed puberty continues to be relevant.<stron...

Background: Hashimito's Thyroiditis is influenced by genetic and environmental factors. Interleukin-2 receptor alpha chain (IL2RA) gene polymorphism and Cytotoxic T-lymphocyte antigen 4 (CTLA 4) gene polymorphism are known to be associated with HT, but have not been established in a Caucasian children population yet. The Fas Apoptotic Inhibitory Molecule 2 (FAIM2) gene polymorphisms impact on the development of HT in children has not been reported yet....

Background: In males with congenital hypogonadotropic hypogonadism (CHH), LH/FSH stimulation of gonads is deficient. In clinical practice, two hormone replacement strategies are employed to induce and maintain virilisation: Treatment with testosterone and gonadotropin replacement with hCG/rFSH.Objective: To delineate the role of gonadotropins in pathways of male androgen biosynthesis and to thereby better define the gona...

Introduction: Ulnar mammary syndrome (UMS) is caused by a mutation of T-box transcription factor 3 (TBX3). It is a rare condition with only a few cases being reported in the literature. We report a child with ulnar mammary syndrome .Case Report: The patient presented to us at 14 years 6 months of age with concerns of failure to gain height which was noted from the age of 11years. His investigations were suggestive of gro...

17β-Hydroxysteroid dehydrogenase type 3 (17β-HSD3) is expressed mostly in the testes and converts the inactive Δ4-androstenedione (A) to testosterone (T). 17β-HSD3 deficiency is a rare autosomal recessive disorder and the most common testosterone biosynthesis defect leading to 46,XY Disorders of Sex Development (DSD). To date, more than 40 mutations of HSD17B3 have been reported. 46,XY patients with 17β-HSD3 deficiency would present with wide variable ...

Background: Monogenic disorders of the immune system are increasingly recognized as a cause of early-onset immune dysregulation and autoimmunity. We recently identified 13 patients with a newly-described syndrome of early-onset polyautoimmunity, including endocrinopathies, and immune deficiency caused by gain-of-function (GOF) variants in the STAT3 gene. STAT3 is a highly conserved transcription factor that affects cytokine-induced changes in gene expression....

Background: X-linked adrenoleukodystrophy (X-ALD) is caused by a defect in the gene ABCD1, which maps to Xq28 and codes for a peroxisomal membrane protein that is a member of the ATP-binding cassette transporter superfamily. This disease characterized by progressive neurologic dysfunction, occasionally associated with adrenal insufficiency.Objective and hypotheses: To identify mutations of gene ABCD1 in Vietnamese patients with X-ALD.</...
