Background: 16p11.2 microdeletion is most common chromosomal anomaly associated with syndromic obesity. The presence of a large number of flanking segmental duplications/low-copy repeat sequences with a high degree of sequence identity in the short arm of chromosome 16 (16p) leads to recurrent deletions and duplications as a consequence of non-allelic homologous recombination. A recurrent 600kb microdeletion is one of the most frequent genomic imbalances in 16...

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 ...

Increasing Lean Body Mass, Phase Angle, and Total Body Water But Decreasing Body Fat Among Short-statured Children Born Small-for-Gestational Age on GH Treatment

Volkl Thomas M K , Stumpf Isabel , Dorr Helmuth-G

Background: There is a small proportion of children born SGA without postnatal catch-up growth who are presented with persistent short stature, low BMI, and decreased lean body mass (LBM). Data on body composition are rarely reported in the literature. Our study addresses the question whether human recombinant GH treatment could affect body composition in these SGA children or not.Design: We included 58 SGA children (n=20 females) with SGA (birt...

Clinical, molecular characterization and long-term follow-up of a patient with neonatal severe hyperparathyroidism

Padeira Goncalo , Carvalho Ana Isabel , Cavaco Branca M. , Virella Daniel , Lopes Lurdes Afonso ,

Introduction: Heterozygous inactivating mutations of the calcium-sensing receptor encoding gene (CASR) cause autosomal dominant familial hypocalciuric hypercalcemia (FHH), whereas mutations that inactivate both alleles cause neonatal severe hyperparathyroidism (NSHPT), a rare and potentially fatal disease. We present the clinical and genetic characterization of a Portuguese family with FHH/NSHPT as well as the long-term follow-up of the proband.<p class="a...

Transient Neonatal Diabetes Mellitus due to not Described Mutation in ABCC8 Gene with Different Behaviour in Affected Family Members

Angeles Santos Mata Maria , Pilar Fernandez Viseras Irene , Torres Barea Isabel , Castano Gonzalez Luis

Neonatal diabetes (ND), classified as either permanent (PND) or transient (TND), occurs in 1/200,000 live births. In 50% cases of TND, remission presents within the first year of life, only to relapse later before puberty in 50% of cases. The most frequent cause is mutation of the 6q24 gene accompanied by mutations in heterozygosis of ABCC8 gene. 80% of mutations in this gene are in novo, due to autosomal recessive inheritance. Such cases respond to treatment with sulfonylurea...
