Background: Gordon Holmes syndrome (GHS) is characterized by cerebellar ataxia/atrophy and normosmic hypogonadotropic hypogonadism (nHH). The underlying pathophysiology of this combined neurodegeneration and nHH remains unknown.Patients and methods: We studied a cohort of multiplex families with GHS through autozygosity mapping and whole exome sequencing.Results: We identified patients from three independent families carrying loss-...

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...

Introduction: In cases of disorder of sex development (DSD), the change between the gender assigned at birth and the individual's chosen gender identity can occur especially after puberty.Aim: was to determine the relationship between genetic sex, gender assigned at birth and gender identity, and the importance of molecular diagnosis.Method:154patients older than 14years of ag...

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 ...

Objective: Glioblastoma 2 (encoded by GLI 2 gene), is an activating zinc-finger transcription factor, involved in the Sonic Hedgehog pathway and embryogenesis of diencephalon and distal extremities Heterozygous mutations of GLI2 gene cause a wide range of clinical phenotype known as holoprosencephaly and holoprosencephaly-like syndrome, pituitary insufficiency, mid-facial hypoplasia, and polydactyly. We, herein, report a novel heterozygous IV...

Evaluation of Primary Hypertriglyceridemia Patients: Ethiology, Phenotype, Treatment

Kaplan Emel Hatun Aytaç , Kumru Burcu , Albayrak Hatice Mutlu , Keskin Mehmet , Karaoglan Murat

Introduction: Plasma triglyceride (TG) is formed by an exogenous pathway taken from food and by an endogenous pathway produced from the liver. Primer hypertriglyceridemia occurs by genetic reasons. Higher TG levels occurs in lipoprotein lipase (LPL), ApoC2, ApoA5 gene defects. Secondary hypertriglyceridemia is caused by obesity, insulin resistance, alcohol and some drugs. In that study, we evaluated 10 patients with primer hypertriglyceridemia regards to clini...

The Effect of Polychlorinobiphenyls on Premature Puberty in Girls

Guven Raziye Burcu , Ozen Samim , Gokşen Damla , Korkmaz Ozlem , Darcan Şukran

Introduction: Studies show that onset of puberty in girls is occurring at increasingly younger ages. Environmental endocrine disruptors are implicated in the etiology of early puberty. Polychlorobiphenyls (PCBs) are one of the endocrine disruptor with proven estrogenic effects.Aim: To investigate the effect of PCBs on premature puberty in girls.Materials-Methods: The study group was selected from girls aged 2–8 years with a di...

Aim: Thyroid hormones are necessary for neurological and psychological well-being in addition to normal growth and development in children and adolescents. Hashimoto thyroiditis is the most common cause of goiter and acquired hypothyroidism and Graves’ disease is the main cause of hyperthyroidism in children and adolescents.
