Introduction: The frequency of solid and hematological malignancies has been reported to be higher in children with Turner syndrome than in the general population. Mycosis fungoides (MF) represent the most common type of cutaneous T-cell lymphoma, which is a low-grade lymphoproliferative disease. To the best of our knowledge, the coexistence of Turner syndrome and MF has not yet been reported. Here, we report a girl with Turner syndrome and MF.<p class="ab...

Introduction: Congenital Adrenal Hyperplasia (CAH) is a chronic disease that requires life-long hormonal replacement therapy. Growth of patients with CAH can be affected by this therapy or the hyperandrogenic effect of the disease. In this study, we aimed to assess the potential effect of CAH and its therapy on final height in Saudi affected patients.Methodology: This is a retrospective cohort study from two tertiary end...

Mutations in genes of the RAS/MAPK signalling pathway have been shown to cause several syndromes characterized by dysmorphic features, growth retardation, cognitive impairment, heart disease and cutaneous abnormalities. The GHrh treatment has been used to improve growth in children with Noonan syndrome.Material and methods: 201 cases of patients referred with clinical suspicion of S. Noonan and other RASopathies was studied. Analysis of ...

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...

Introduction: Short stature is a multifactorial condition caused by both genetic and environmental factors. Genetic causes include chromosomal disorders and diseases inherited by monogenic and multifactorial inheritance. The purpose of genetic evaluation in short stature is not only for diagnosis, but also to provide additional information to the patients and their families about prognosis of the disease, treatment approaches and genetic counseling.<p clas...

Introduction: Our Centre is an international referral centre for genetic analysis of children with short stature (SS) and features of GH/IGF-1 resistance. Following candidate gene and whole exome sequencing, diagnoses for ~50% patients remained elusive. Copy number variation (CNV) has not previously been investigated in GH/IGF-1 resistance and we hypothesised that CNVs contribute to the phenotype in our undiagnosed cohort.Experimental Design and Methodol...

Background: Aromatase excess syndrome (AEXS) (OMIM 139300) is a rare condition characterized with gynecomastia in boys and macromastia in girls. Estrogen excess in boys can lead to prepubertal and pubertal gynecomastia, bone age progression and short adult stature. While most of girls are usually asymptomatic, there are few reported female patients with excessive breast growth, early puberty, menstrual irregularities, and short adult stature. Male and female children with AEXS...

Background: FOP is an ultra-rare, severely disabling genetic disorder characterised by progressive heterotopic ossification (HO) following flare-ups. The median age at diagnosis is 5 years, and patients are managed by multiple specialties. No study to date has provided a longitudinal evaluation of FOP. Final data are presented for participants, aged <25 years, enrolled in the first 36-month, prospective, global natural history study of FOP (NCT02322255).</...

Background: Hypoglycaemia due to congenital hyperinsulinism (CHI) is the commonest cause of severe, recurrent hypoglycaemia in childhood. Previous follow up studies have focused on neurodevelopmental status which is noted to be delayed in as many as 48% of cases. There has been less emphasis on other long-term outcomes in patients with CHI. Given the requirement for high volume carbohydrate in most patients, there are concerns regarding the adverse effects on ...

Though up to fourteen different MODY subtypes have been so far described, there are no studies in the literature which have determined their actual frequency and prevalence in pediatric patients.Objectives: To identify the underlying molecular basis in a cohort of pediatric patients with a suspected clinical diagnosis of MODY by targeted NGS.Materials/Methods: Cohort of 60 patient fulfilling MODY c...
