BACKGROUND: Adrenal hypoplasia is a rare congenital disorder, which can be classified into a non-syndromic form, without extra-adrenal features, and a syndromic form, with such features. Despite biochemical and molecular genetic evaluation, etiologic diagnosis cannot be performed in many patients with adrenal hypoplasia. CASE PRESENTATION: The patient in this case was a boy born at 31 weeks of gestation with a weight of 882 g (< 3rd percentile) to non-consanguineous parents...

INTRODUCTION: Recently recessive mutations in sphingosine-1-phosphate lyase (SGPL1) have been published as a cause of syndromic congenital nephrotic syndrome with adrenal insufficiency. We have identified a case with fetal hydrops and brain malformations due to a mutation in SGPL1. CASE REPORT: We report a patient presenting with severe fetal hydrops, congenital nephrotic syndrome and adrenal calcifications. MRI imaging showed generalized cortical atrophy with simplified gyral pattern and hypoplastic temporal lobes as well as cerebellar hypoplasia and hyperintensity in the pons...

OBJECTIVE To investigate the correlation of 21-hydroxylase deficiency (21-OHD) with male testicular dysplasia. METHODS Clinical data of 8 infertile males with congenital adrenal hyperplasia due to 21-OHD was retrospectively analyzed. In addition, potential mutations of the CYP21A2 gene was detected. RESULTS All patients were referred because of azoospermia or severe oligospermia and had small testis with averaged testicular volume of 6.1 mL. Three patients had testicular adrenal rest tumors. Endocrinologic examinations revealed low levels of leutinizing hormone and follicular stimulating hormone, normal or elevated testosterone, elevated progesterone, elevated or normal adrenocoticotropic hormone, and low or normal cortisol...

BACKGROUND: X-linked congenital adrenal hypoplasia (X-linked AHC) is characterized by acute onset of primary adrenal insufficiency in infancy or early childhood and hypogonadotropic hypogonadism (HH) at puberty. Mutations in NR0B1, the gene located on Xp21.3 and encoding an orphan nuclear receptor named DAX1, are responsible for this disease. METHODS: The entire coding region of the NR0B1 gene of a 14-year-old X-linked AHC proband as well as his family members was sequenced...

BACKGROUND: Myelodysplasia, infection, restriction of growth, adrenal hypoplasia, genital phenotypes and enteropathy (MIRAGE) syndrome is a recently described congenital disorder caused by heterozygous SAMD9 mutations. The phenotypic spectrum of the syndrome remains to be elucidated. METHODS AND RESULTS: We describe two unrelated patients who showed manifestations compatible with MIRAGE syndrome, with the exception of haematological features. Leucocyte genomic DNA samples were analysed with next-generation sequencing and Sanger sequencing, revealing the patients to have two de novoSAMD9 mutations on the same allele (patient 1 p...

A 2-month-old boy presented with adrenal insufficiency, impaired liver function, hypertriglyceridemia, significantly elevated creatine kinase and electrolyte disturbance. Microarray comparative genomic hybridization (aCGH) analysis test showed a pathogenic 8.7 Mb deletion in the short arm of chromosome X (Xp21.3 - p21.1) and confirmed the diagnosis of complex glycerol kinase deficiency (cGKD). He was treated with hydrocortisone, coenzyme Q10 and L-carnitine and was subsequently followed up for 4 years. His serum cortisol levels returned to normal one week later after treatment, but the serum creatine kinase, triglyceride and aminotransferase levels were progressively increased along with mental retardation and decreased muscular strength...

We present a 6-week-old male infant with persistent hyperbilirubinemia, hypertriglyceridemia, elevated creatine kinase levels, and transaminitis since the second week of life. When he developed hyperkalemia, clinical suspicion was raised for adrenal insufficiency despite hemodynamic stability. A full endocrine workup revealed nearly absent adrenocorticotropic hormone. Coupled with his persistent hypertriglyceridemia (peak of 811 mg/dL) and elevated creatine kinase levels (>20 000 U/L), his corticotropin level lead to a clinical diagnosis of complex glycerol kinase deficiency (GKD), also known as Xp21 deletion syndrome...

P450 oxidoreductase deficiency (PORD) is a variant of congenital adrenal hyperplasia that is caused by POR gene mutations. The POR gene encodes a flavor protein that transfers electrons from nicotinamide adenine dinucleotide phosphate (NADPH) to all microsomal cytochrome P450 type II (including 21-hydroxylase, 17α-hydroxylase 17,20 lyase and aromatase), which is fundamental for their enzymatic activity. POR mutations cause variable impairments in steroidogenic enzyme activities that result in wide phenotypic variability ranging from 46,XX or 46,XY disorders of sexual differentiation, glucocorticoid deficiency, with or without skeletal malformations similar to Antley-Bixler syndrome to asymptomatic newborns diagnosed during neonatal screening test...

BACKGROUND: Salt-wasting represents a relatively common cause of emergency admission in infants and may result in life-threatening complications. Neonatal kidneys show low glomerular filtration rate and immaturity of the distal nephron leading to reduced ability to concentrate urine. METHODS: A retrospective chart review was conducted for infants hospitalized in a single Institution from 1(st) January 2006 to 31(st) December 2015. The selection criterion was represented by the referral to the Endocrinology Unit for hyponatremia (serum sodium <130 mEq/L) of suspected endocrine origin at admission...

BACKGROUND: Hydrops foetalis is defined as excessive fluid accumulation within the foetal extravascular compartments and body cavities. It has been described in human and veterinary medicine, but despite several descriptive studies its aetiology is still not fully clarified. Pulmonary hypoplasia and anasarca (PHA) syndrome is a rare congenital abnormality in cattle that is characterised by hydrops foetalis including extreme subcutaneous oedema (anasarca) and undeveloped or poorly formed lungs (pulmonary hypoplasia)...

Adrenal hypoplasia is a rare, life-threatening congenital disorder. Here we define a new form of syndromic adrenal hypoplasia, which we propose to term MIRAGE (myelodysplasia, infection, restriction of growth, adrenal hypoplasia, genital phenotypes, and enteropathy) syndrome. By exome sequencing and follow-up studies, we identified 11 patients with adrenal hypoplasia and common extra-adrenal features harboring mutations in SAMD9. Expression of the wild-type SAMD9 protein, a facilitator of endosome fusion, caused mild growth restriction in cultured cells, whereas expression of mutants caused profound growth inhibition...

Congenital X-linked adrenal hypoplasia (AHC) is a rare disease characterized by primary adrenal insufficiency before adolescence and by hypogonadotropic hypogonadism (HHG) during adolescence. In this paper, we present a Chinese family with AHC. Two brothers, misdiagnosed with adrenal insufficiency of unknown etiology at the age of 9, were correctly diagnosed with AHC when delayed puberty, HHG, and testicular defects were observed. We investigated the clinical features and identified the dosage-sensitive sex reversal AHC critical region of the X chromosome gene 1 (DAX-1) mutation in this kindred...

OBJECTIVE AND DESIGN: The proinflammatory cytokine tumor necrosis factor alpha (TNF-α) has an inhibitory role in gonadal functions particularly in the steroidogenesis of Leydig cells. A detailed understanding of the mechanisms by which TNF-α regulates testicular steroidogenesis will be helpful in the design of novel clinical interventions for the treatment and prevention of male reproductive disorders. Here, we report that TNF-α-mediated activation of DAX-1 (dosage-sensitive sex reversal adrenal hypoplasia congenital critical region on X chromosome, gene 1) is involved in the inhibition of Leydig cell steroidogenesis...

Xp21 continuous gene deletion syndrome is characterized by complex glycerol kinase deficiency (GK), adrenal hypoplasia congenital (NROB1), intellectual disability and/or Duchenne muscular dystrophy (DMD). The clinical features depend on the size of the deletion, as well as on the number and the nature of the encompassed genes. More than 100 male patients have been reported so far, while only a few cases of symptomatic female carriers have been described. We report here detailed clinical features and X chromosome inactivation analysis in two unrelated female patients with overlapping Xp21 deletions presenting with intellectual disability and inconstant muscular symptoms...

Nuclear receptors (NRs) are ligand-activated transcription factors that play an important role in metabolism, homeostasis, differentiation and development regulation. NRs are also involved in pathogenesis of various diseases. For most of NRs natural ligands are known. Ligand-activated NRs bind specific nucleotide sequences in target genes and induce their expression. DAX1 protein is an unusual member of NR superfamily that does not have ligand and lacks typical DNA-binding domain. It was established 20 years ago that DAX1 plays a critical role in regulation of adrenal and gonadal development and in biosynthesis of steroid hormones, however the molecular mechanisms of its action remained not fully understood...

INTRODUCTION: X-linked adrenal hypoplasia congenita (AHC) is a rare cause of adrenocortical insufficiency. Early postnatal diagnosis may prevent severe hypoglycemia, Addisonian crises and death. Low maternal estriol (E3) levels in the second trimester of pregnancy could indicate the possibility that the fetus suffers from a disorder that causes adrenal insufficiency. Suspicion is based on the fact that E3 originates from dehydroepiandrosterone (DHEA) synthesized in the fetal adrenals...

Multiple or supernumerary nostril is a rare congenital anomaly with unknown etiology. The first case was reported by Lindsay as bilateral supernumerary nostrils. Supernumerary nostril cases are mostly unilateral and isolated. They are also reported with other congenital malformations like facial clefts and congenital anomalies like congenital auricular hypoplasia, congenital cataracts, eusophageal atresia and patent ductus arteriosus. Here, we report a case of supernumerary nostril with congenital adrenal hyperplasia...
