A unique combination of Klinefelter syndrome and Three M Syndrome in a boy with short stature

Lee Mi-Seon , Lee Rosie , Lee Sang-Eun , Kwak Na-eun , Kwon Soon-Hak , Moon Jung-Eun

Introduction: Klinefelter syndrome (KS) is most common sex chromosomal aneuploidy in males. The typical clinical features are tall stature with long extremities, small testis, and learning disabilities. Three M syndrome is an extremely rare genetic disorder characterized by short stature, craniofacial abnormality and skeletal malformations. We report a unique case of short stature in KS due to three M syndrome.Case: A 9-...

Background: Primary ovarian insufficiency (POI) is genetically mediated in up to 30% of cases. Many genes associated with POI have roles in early ovary developmental processes, including meiosis.Objectives: We investigated the genetic mechanism underlying early-onset POI in three young women presenting with absent puberty: two sisters from a consanguineous pedigree and a third unrelated proband.<st...

Background: Persistent Müllerian duct syndrome (PMDS) is a Disorder of Sex Development (DSD) caused by mutations in genes encoding anti-Müllerian hormone (AMH) or its type II receptor (AMHR2) with autosomal recessive transmission. Objective: To report a case of transverse testicular ectopia (TTE), associated with PMDS, initially presented as an obstructed inguinal hernia.Case presentation: An 18- days- old male infant, wi...

Diagnostic precision of the Tri-Ponderal Mass Index (kg/m3) to identify the metabolic risk phenotype in obese children and adolescents.

Arciniegas Larry , Tomasini Rosangela , Vega Elizabeth , Fabregas Ana , Clemente Maria , Yeste Diego ,

Introduction: The metabolically healthy obese phenotype (MHOF) defines obese patients who have preserved insulin sensitivity and who do not have metabolic complications: lower risk of cardiovascular disease and type 2 diabetes in adulthood. Recent studies indicate that TMI (kg/m3) estimates the percentage of body fat more accurately than the BMI and it has been proposed to substitute the use of the BMI z-score values by those of the TMI. TMI values ...

Diagnostic accuracy of Tri-Ponderal mass index (kg/m3) for identifying glucose intolerance in obese children and adolescents.

Arciniegas Larry , Mogas Eduard , Tomasini Rosangela , Fabregas Ana , Clemente Maria , Yeste Diego ,

Introduction: The identification of obese patients with increased susceptibility and risk for glucose intolerance and type 2 diabetes requires an oral glucose tolerance test (OGTT). Reference values for Body mass index (BMI) and Tri-Ponderal mass index (TMI) according to age and sex of healthy children in Spain without malnutrition or obesity have recently been published (*). TMI values remain very uniform in both boys and girls from the age of 8 to 18 years, ...

Poor Weight Gain in Prader-Willi Syndrome – Not Always Over-restriction Consider Coeliac Disease

Lateva M , Kassim A , Meade C , Maher R , McCrann A , Roche E

Introduction: Prader-Willi Syndrome (PWS) is a complex genetic condition associated with feeding difficulties, hypotonia, developmental delay in infancy; hyperphagia leading to extreme obesity, growth failure and behavioral problems in childhood. Coeliac disease (CD), is an autoimmune disease characterized by gluten intolerance and a variety of symptoms most commonly diarrhea or constipation and failure to thrive. In PWS the challenge is to optimize growth while avoiding obesi...

Evaluation of Two New Anti-Müllerian Hormone Assays for the Investigation of Disorders of Sexual Development in Neonates

Ho Clement K M , Setoh Johnson W S

Background: Anti-Müllerian hormone (AMH) inhibits the in utero growth of the Müllerian structures in female fetuses. In neonates with suspected disorders of sexual development (DSDs), the presence of testicular tissues and functioning Sertoli cells can be investigated by testing for serum AMH concentration.Objective: To evaluate the performance of two new AMH assays in a hospital laboratory.Method: The technical performan...

Gender Identity Prediction in Adulthood by HTP Test (House-Tree-Family) in 46, XY DSD Patients

Batista Rafael Loch , Inacio Marlene , Oliveira Jr Ari , Brito Vinicius N , Costa Elaine M F , Domenice Sorahia , Mendonca Berenice B

Background: Patients with 46, XY DSD present conflicts and issues related to gender identity (GI) and change to male social sex in patients registered in the female social sex is not rare. The HTP test is a projective psychological test, which assesses aspects related to sexual identification. GI in this test is defined as female (F), male (M) or ambiguous.Objective and hypotheses: To evaluate GI in patients with 46, XY DSD by the HTP test and compare th...

Age at Onset of Weight Gain in Prader–Willi Syndrome is Often Between 1 and 2 Years, Preceding the Hyperphagic Phase; Implications for Management

Donaldson Malcolm , Hammed Noran Abu-Of , Shaikh M Guftar

Background: Prader–Willi syndrome (PWS) results from loss of paternally imprinted genes from the 15q11–13 region and causes hypotonia with weight faltering in infancy, followed later by obesity which is classically attributed to hyperphagia.Objective and hypotheses: To determine, where possible, the age at onset of unwanted weight gain (as opposed to actual obesity) in children with PWS attending a specialist clinic.Metho...

Genetic Variation of AMH Signaling Affects AMH and Inhibin B Levels in Healthy Peripubertal Girls

Hagen Casper P , Almstrup Kristian , Main Katharina M , Juul Anders

Background: Anti-Müllerian hormone (AMH) is produced by small growing ovarian follicles. It inhibits both FSH induced maturation of follicles as well as aromatase activity. Genetic variation of AMH signalling is associated with age at menopause and circulating oestradiol levels, i.e. AMH rs10407022 T>G (intragenic) and AMHR2 rs11170547 C>T (putative enhancer).Objective and hypotheses: This present study aims to investigate ...
