Background: Monogenic defects are among the significant causes of early-onset non-syndromic severe obesity in childhood. Identifying the genetic cause of obesity can guide for treatment. The aim of our study is to investigate the clinical and biochemical features of patients with early-onset severe obesity and evaluate the underlying molecular diagnosis.Materials and Methods: A total of 39 patients (M/F: 22/17) with non-...

Introduction: Brachydactyly mental retardation syndrome (BDMR, #MIM600430) is a rare genetic disorder caused by deletions in 2q37 region, characterised by intellectual disability, facial features, and skeletal abnormalities. This case delineates the clinical progression and growth hormone (GH) therapy response of a patient with a unique phenotype resulting from an unbalanced derivative of a paternal balanced translocation, leading to a 2q37 deletion and 14q32 ...

Key words: Dysgerminoma, gonadoblastoma, virilizationIntroduction: Gonadoblastoma is a rare ovarian tumor composed of sex cord cells and primitive germ cells. Although it is frequently seen in patients with 46,XY gonadal dysgenesis, it is also rarely seen in patients with a 46,XX karyotype. Here, we report a girl with a 46,XX karyotype presenting due to an uncommon cause of virilization, which was caused by bilateral gon...

Background: Bardet-Biedl syndrome (BBS) is a rare, autosomal recessive, clinically and genetically heterogeneous, pleiotropic disease characterized by the immotile primary cilia, leading to an MC4R pathway impairment. In addition to syndromic features, patients present with hyperphagia, early-onset obesity, metabolic syndrome (MetS) and increased risk of type 2 diabetes. Here, we aimto describe metabolic features and MetS z-score in a group of rare BBS cases.<...

Background: P450 oxidoreductase (POR) deficiency is a rare cause of congenital adrenal hyperplasia (CAH) with a wide spectrum of clinical phenotypes including glucocorticoid deficiency, difference/disorder of sex development (DSD), skeletal malformations, and Antley-Bixler syndrome. We describe the clinical and molecular characteristics of a large cohort with POR deficiency with long-term data.Methods: The medical record...
