Context: Polycystic ovary syndrome (PCOS) is defined by androgen excess and ovarian dysfunction in the absence of a specific physiological diagnosis. The best clinical marker of androgen excess is hirsutism, while the best biochemical parameter is still a matter of debate. Current consensus guidelines recommend serum free testosterone as the most sensitive serum parameter to measure androgen excess. Recently, however, novel active androgens and androgen metabo...

The physiology of adrenarche, i.e. the development of the zona reticularis of the adrenal cortex, is mostly unknow. Some genes of steroidogenic enzymes need to be down- (HSD3B2) while others upregulated (e.g. CYB5) to enhance androgen production in zona reticularis, but it is not known how this is regulated. Micro RNAs (miRNAs) are small non-coding RNAs that can affect gene expression at posttranscriptional level. We hypothesized that miRNAs might be involved in regulating adr...

Introduction: Microarray (SNP array) method offers a powerful full genome scanning opportunity in the diagnosis of disorders of sex development (DSD).Aim and Method: We aimed to determine the copy number variations (CNVs) by using the microarray method to elucidate the molecular etiology in DSD patients. The variants found were scored according to the American College of Medical Genetics and Genomics criteria.<p clas...

Gender uncertainty is stressful condition for children and their families. Gender assignment in children with disorder of sex development (DSD) is considered as a medical emergency. Influencing factors to consider when debating gender assignment include medical diagnosis, external genital appearance, potential of fertility and sexual, therapeutic and/or surgical intervention options, views and desires of patients and families, situation of social-cultural factors, the psycholo...

Introduction: Various types of mutations in GHRHR cause isolated growth hormone deficiency type 1B. Here, we report the clinical features associated with deletion of whole GHRHR gene for the first time.Case: A four-year–and-nine-month-old otherwise healthy girl was admitted due to short stature. She was born at term with a birthweight of 3750 gr. Her height velocity slowed down after 2 years of age. The mother (157.8 cm, −0.8...

Introduction: 17α-hydroxylase deficiency (17OHD) is a rare form of congenital adrenal insufficiency characterized with decreased cortisol and sex steroid biosynthesis, overproduction of ACTH, and increased mineralocorticoids. The overproduction of corticosterone hinders the symptoms of glucocorticoid deficiency and causes sodium retention, hypertension, and hypokalemia in severe cases. Affected 46,XX and 46,XY individuals are phenotypically female in the...

Introduction: Proopiomelanocortin (POMC) deficiency is a rare disease characterized by central adrenal insufficiency, early-onset obesity, red hair, and impaired skin pigmentation. This disease is caused by mutations of POMC that is localized in 2p23.3. Here, we aimed to present a case with central adrenal insufficiency, red hair, and rapid weight gain and who was detected frameshift mutation in the POMC.Case</s...

Background: Congenital adrenal hyperplasia (CAH) is the most common form of primary adrenal insufficiency in children. 21-hydroxylase enzyme deficiency (21-OHD) occurs in 90–95% of all cases of CAH. Despite it being a treatable condition, if unrecognized, CAH may present with life-threatening cardiovascular collapse. Mortality in the first years is reported to be higher than in the general population. Neonatal screening for CAH is effective in detecting the salt-wasting f...
