Background: Persistent Müllerian Duct Syndrome (PMDS) needs to be considered in boys (46, XY) presenting with bilateral cryptorchidism or unilateral cryptorchidism associated with an inguinal hernia. Anti-Müllerian hormone (AMH) gene as well as Anti-Müllerian hormone Receptor (AMHR 2) gene mutations have been identified in PMDS boys.Aim and methods: To report a novel mutation in the AMHR 2 gene in monochorionic d...

Background: Newborn screening for CAH is effective in identifying the severe cases; however, the high rate of false-positive (FPR) results remains an important issue. Therefore, positive neonatal results must be confirmed by serum 17OHP levels, which present a great overlap among all forms.Objective and hypotheses: To evaluate the utility of molecular analysis to improve CAH diagnosis in NBS program.Method: Between 1999 and 2014, 8...

Background: Main concerns of Congenital Adrenal Hyperplasia Newborn Screening (CAH-NBS) are the high false-positive results (FPR) rate, low positive predictive value (PPV) and heterogeneity of confirmatory tests. Considering the CAH-NBS implementation in our country, our.Objectives: Objectives are to optimize the Neonatal 17OH-Progesterone (N17OHP) cutoffs and to evaluate the best serum confirmatory test.Methods: 473 983 newborns w...

A female patient was firstly evaluated at the age of 12 years, complaining of headaches and visual loss. Physical examination demonstrated adequate height and weight, Tanner stage P1B1. Papillary edema was confirmed by fundus examination. MRI showed a pituitary macroadenoma, 6.6×7.3×6.1 cm with compression of the optic chiasm and bilateral cavernous sinus invasion. The first prolactin value obtained was 169.164 uUI/ml (normal<210) with the other pituitary axis wi...

Background: Genetic defects in NKX2.1 (chromosome 14q13) are associated with hypothyroidism, choreo-athetotic movements and respiratory distress, known as the “Brain-Lung-Thyroid syndrome”.Objective and hypotheses: To identify the genetic basis of a disorder compatible with the “NKX2.1 syndrome” and extra features outside the typical triad.Patients and methods: 10-year old girl with congenital ...

Background: Most children with idiopathic short stature (ISS) have a delayed bone age (BA). ISS with advanced BA is far less common. We studied three families with autosomal dominant short stature, unexplained BA acceleration, and premature growth cessation.Objective and hypotheses: To identify the genetic cause of this condition and describe its clinical spectrum.Method: Whole exome sequencing was performed in selected individuals...

Background: Recent clinical guidelines recommend that all patients with non-classic congenital adrenal hyperplasia (NCCAH) on glucocorticoid therapy (GC) need to be informed about stress doses and suggest the use of GC in the subgroup of patients with low cortisol response during periods of stress even though they are not on GC.Objective and Hypotheses: To study the response of cortisol to ACTH 250 μg i.v. (Synacthen®, Novartis) in p...

Background: The immunoglobulin superfamily member 1 (IGSF1) gene encodes a plasma membrane glycoprotein enriched in pituitary and testes. Loss-of-function mutations in IGSF1 cause an X-linked syndrome of central hypothyroidism (CeH), macroorchidism, and delayed pubertal rise of testosterone despite normal timing of testicular growth. This syndrome was discovered in patients with CeH; therefore, it is presently unknown whether IGSF1 mutations also cau...

Background: microRNAs (miRNAs) are a class of small (18–25 nucleotides), non-coding RNA molecules. They play an important role in the regulation of gene expression by either suppressing translation of genes or inducing their mRNA degradation. Several miRNA species are expressed in adipose tissue and involved in adipocyte function.Objective and hypotheses: Obesity leads to the infiltration of macrophages into adipose tissue causing local inflammation...

Background: MEHMO (microcephaly, epilepsy, hypogenitalism, mental retardation, obesity) is a rare disorder with X-linked inheritance. Only three families with this disorder were described previously, with the linkage to a region on X chromosome. No specific gene has been identified so far.Aims and objectives: The aim was to identify the genetic etiology in two unrelated Slovak male probands (4.5 and 1.5 years old respectively) with the clinical diagnosis...
