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...

We report a 70 year old woman presenting with increased libido and mild but rapid onset virilism. Investigations showed markedly elevated androstenedione and 17 hydroxyprogesterone (17OHP) misdirecting to possible late-onset congenital adrenal hyperplasia (CAH). High serum testosterone and oestrogens with suppressed gonadotrophins, however, indicated an androgen secreting tumour. A normal dehydroepiandrosterone sulphate (DHEAS) and elevated inhibins A and B indicated the tumour was ovarian in origin, which was confirmed on pelvic examination and imaging...

11β-Hydroxylase deficiency is the second most frequent type of congenital adrenal hyperplasia and is more common in those of Turkish descent than in other populations. The purpose of this study is to examine the spectrum of CYP11B1 gene mutations in Turkish patients with 11β-hydroxylase deficiency. Twenty-eight patients from 24 families, ages ranging from 0.1 to 7 years, were included in the study. Clinical diagnosis was based on virilization and high levels of 11-deoxycortisol. Twenty-six cases exhibited the classical and 2 cases the non-classical form...

Congenital adrenal hyperplasia (CAH) is one of the most common diseases transmitted in an autosomal recessive manner and is caused by mutations of enzymes which are responsible for the process of adrenal steroidogenesis. According to the impairment of enzymes involved in steroidogenesis, several types of CAH can be distinguished. The most common type is associated with mutations in the CYP21A2 gene, encoding 21-hydroxylase enzyme and has different clinical forms: Classical (in which there are two types: salt wasting and simple virilization) and non-classical, characterized by less severe symptoms and late onset...

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is caused by mutations in the CYP21A2 gene. The residual enzyme activity is strongly associated with the phenotype. We describe a rare case of CAH with a rare CYP21A2 mutation. The patient was a one-year-old Japanese boy. At 16 days old, he was referred to our hospital because of elevated serum 17-OH-progesterone (17-OHP) levels in neonatal screening. The compound heterozygous mutations (IVS2-13 A/C>G, and p.E431K) in CYP21A2 were identified at 2 months old, and we diagnosed non-classical CAH, since he did not have significant physical signs (pigmentation and salt-wasting)...

Although hirsutism is classically part of the clinical presentation of polycystic ovarian syndrome (PCOS), congenital adrenal hyperplasia and Cushing's syndrome (CS), CS associated with underlying late-onset congenital adrenal hyperplasia (LCAH) in an adult has not been previously reported. We herein present the case of a 25-year-old woman who was followed for PCOS for seven years. After undergoing detailed tests described within the text, she received the diagnosis of LCAH and was found to have point mutations...

AIM: Aim of the study was to investigate the need to perform the adrenocorticotropic hormone (ACTH) stimulation test by recognizing the importance of a second look at basal serum 17-alpha hydroxyprogesterone (17-OHP) levels and calculating new serum 17-OHP cut-off level. METHODS: A total of 142 patients who had hyperandrogenism symptoms and had basal serum 17-OHP levels of higher than 1.3 ng/mL were scheduled to have an ACTH stimulation test performed. Prior to ACTH stimulation, 17-OHP levels were recorded and as second-look levels...

We report a novel NR0B1 mutation in a patient affected with X-linked adrenal hypoplasia congenita (X-AHC). The proband first presented with a generalized convulsion at 11 years, 4 months. His clinical and biochemical presentations were consistent with adrenal insufficiency. His basal 17-hydroxyprogesterone (17-OHP) level was not high, and the poor response in 17-OHP on ACTH stimulation test excluded congenital adrenal hyperplasia. At 14 years of age, he did not show any signs of puberty, with low levels of LH, FSH, and testosterone and unresponsiveness to lutenizing hormone releasing hormone stimulation test...

Cryptic deletions in balanced de novo translocations represent a frequent cause of abnormal phenotypes, including Mendelian diseases. In this study, we describe a patient with multiple congenital abnormalities, such as late-onset congenital adrenal hyperplasia (CAH), primary ovarian failure and Ehlers-Danlos syndrome (EDS), who carries a de novo t(6;14)(p21;q32) translocation. Genomic array analysis identified a cryptic 1.1-Mb heterozygous deletion, adjacent to the breakpoint on chromosome 6, extending from 6p21...

RANDOMIZED CONTROLLED TRIAL
Anne Bachelot, Philippe Touraine
Congenital adrenal hyperplasia (CAH) is the commonest genetic endocrine disorder. Mutations in the 21-hydroxylase gene account for 95 % of cases. CAH is classified according to symptoms and signs and to age of presentation. The clinical phenotype is typically classified as classic, the severe form, or nonclassic (NCF), the mild or late-onset form. Classic CAH is a life-long chronic disorder. In childhood, treatment focuses on genital surgery and optimization of growth and pubertal development. Priorities change with increasing age, typically focusing on fertility in early adult life and prevention of metabolic syndrome and osteoporosis in middle and older age...

The most common cause for menstrual abnormality and virilization in children and adolescents would be congenital adrenal hyperplasia. An elevated 17(OH) progesterone is invariably seen in this condition. Aromatase deficiency can also lead to a similar presentation but differs in several aspects. The age of onset of the clinical manifestations, the phenotype, biochemical abnormalities and karyotype help us to arrive at a definitive diagnosis. However sometimes the history is atypical, biochemical abnormalities may overlap between the different conditions and prior treatment may modify the clinical features...

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency accounts for 90%-95% of cases. This autosomal recessive disorder has a broad spectrum of clinical forms, ranging from severe or classical, which includes the salt-wasting and simple virilizing forms, to the mild late onset or nonclassical form. Most of the disease-causing mutations described are likely to be the consequence of nonhomologous recombination or gene conversion events between the active CYP21A2 gene and its homologous CYP21A1P pseudogene...

REVIEW
Selma Feldman Witchel
Non-classic or late-onset congenital adrenal hyperplasia (NCAH) due to 21-hydroxylase deficiency is one of the most common autosomal recessive disorders. Reported prevalence is approximately 1 in 1000. Affected individuals typically present due to signs and symptoms of androgen excess. The purpose of this review is to provide current information regarding the pathophysiology, molecular genetics, and management of this common disorder. The treatment of NCAH needs to be directed towards the symptoms. For affected children, goals of treatment include normal linear growth velocity, normal rate of skeletal maturation, "on-time" puberty...

The aim of the authors is to present two cases which raise the possibility of an association between polycystic ovarian syndrome/hyperandrogenism and ovarian cyst torsion in peripubertal girls. Androgen excess may cause more frequently ovarian cyst formation in premenarcheal or young adolescents with undiagnosed polycystic ovarian syndrome than in adults. The authors recommend that polycystic ovarian syndrome as well as late onset congenital adrenal hyperplasia should be considered in peripubertal adolescents with ovarian cyst torsion...

AIMS: Caucasian patients with disorders of sex development (DSD) are at a high risk of developing germ cell cancer (GCC). GCC is prominent in young adults in Western countries, while the incidence is significantly lower in Asia. So far, the risk of GCC in Asian DSD patients is unknown. METHODS AND RESULTS: A detailed study of gonad histology , morphology and immunohistochemistry (OCT3/4, testis-specific protein Y-encoded, VASA, SCF/KITLG, SOX9, FOXL2) of 16 Indonesian DSD patients was undertaken...

We present the diagnostic approach of a patient with adrenal incidentalomas. A 72-year-old African American male had a CT scan of the abdomen showing right and left adrenal masses measuring 5 × 3.5 cm and 3.7 × 2.9 cm, respectively. The patient had negative hormonal workup. The radiologist insisted that the CT findings are consistent with adrenal hyperplasia, and therefore he underwent ACTH stimulation to rule out late-onset congenital adrenal hyperplasia (CAH). The stimulation test revealed that 17-hydroxyprogesterone and 11-deoxycortisol increased to levels high enough to confirm CAH, but cortisol had exaggerated response as well, thus making the diagnosis of CAH unlikely where metabolism is shifted to precursors...
