Background: Hypospadias is one of the most common congenital anomalies in males. Surgical repairing aims to improve the aesthetic and functional outcome. The success rate of hypospadias repairing is variable according to the severity of the malformation with a complication rate(CR) of almost 60% in proximal forms. Testosterone treatment before surgery is still controversial and its impact on surgical outcomes, and the best regimen for administration, is unclea...

Background/Aims: Short stature is a common reason for presentation to paediatric endocrinology clinics. Getting to a diagnosis of short stature is a multi-step, complex process of tests that only in a few cases save a diagnosis. As genetic plays a strong role in height, we sought to identify known and novel genetic causes of short stature.Methods: We recruited 18 children with severe short stature, we conducted whole exo...

Background: Achondroplasia (ACH), the most common short-limbed skeletal dysplasia, is characterized by impaired endochondral ossification resulting from gain-of-function pathogenic variants in the fibroblast growth factor receptor 3 (FGFR3) gene, a negative regulator of endochondral bone growth. People with ACH are at risk for several significant co-morbidities, including brainstem compression due to foramen magnum stenosis, sleep-disordered breathing, chronic...

Oligogenic Inheritance May Explain The Phenotypic Variability and Incomplete Penetrance of Deleterious GL1I2 Variants in Congenital Hypopituitarism

Background: GL1I2 encodes a zinc-finger transcription factor expressed in the developing hypothalamus and in Rathke's pouch, the embryonic precursor of the pituitary gland. Pathogenic GL1I2 variants have been implicated in the etiology of the broad clinical spectrum of congenital hypopituitarism (CHY): holoprosencephaly, midline facial abnormalities, Culler-Jones syndrome, combined pituitary hormone-deficiency (CPHD) and isolated GH-defi...

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...

Whole Exome Sequencing to Identify Causative Variants in a Female Patient with Early Onset Obesity and Intellectual Disability: A New Case of Borjeson-Forsman-Lehmann syndrome

The epidemic spread of obesity in children has triggered the commitment of scientific research, which has allowed us to understand its genetic basis; the different forms of genetic obesity share common clinical aspects, making it difficult to achieve a molecular diagnosis based only on our clinical suspicion. We report a female patient presented with neonatal hypotonia, hyperphagia and early onset excessive weight gain, strabismus and high hypermetropia. Regarding her neurodev...

Central diabetes insipidus (CDI) in children is caused by brain tumors, Langerhans cell histiocytosis (LCH), trauma, infections, or genetic abnormalities in about 60% of the cases. In the remaining 40%, CDI is idiopathic even after detailed clinical and radiological investigations. Aim of the study was to assess whether measurement of serum antibodies against human growth hormone (GH) could aid in the identification of the etiological factors for CDI.<p class="abst...

A point mutation of SH2B1: a new cause of monogenic obesity?

CriscuoloSabrina , Ubertini Graziamaria , d'Aniello Francesco , Mirra Giulia , Mucciolo Mafalda , Elisa Amodeo Maria , Deodati Annalisa , Rapini Novella , Cappa Marco

Early identification of monogenic obesity, a rare condition, is quite challenging for pediatricians. Src-homology-2 (SH2) B adapter protein 1 (SH2B1) is an important component in the leptin-melanocortin pathway and it is found to play an important role in leptin and insulin signaling. In humans a rare deletion of a 220-kb region on chromosome 16p11.2 encompassing approximately 9 genes, including the SH2B1 gene, is associated with a highly penetrant form of isolated severe earl...
