Background: Idiopathic hypogonadotropic hypogonadism (IHH) is a congenital heterogeneous disorder characterized by a deficiency of gonadotropin-releasing hormone. IHH can be categorised as IHH with anosmia/hyposmia (Kallmann syndrome: KS) or as normosmic (n)IHH. More than 25 genes have been identified in IHH. Nevertheless, patients with IHH are genetically diagnosed in only less than 50%.Objective: The objective of this study is to confirm the applicatio...

Background: The IGF1 receptor (IGF1R) gene is located on the distal long arm of chromosome 15 (15q26.3). Heterozygous inactivating mutations of the IGF1R gene cause intrauterine and postnatal growth failure and mental retardation.Objective: The purpose of this research is to determine the most effective GH treatment for patients with IGF1R haploinsufficiency due to heterozygous deletion.Method: We investigated the clinical course o...

Background: Wiedemann–Steiner syndrome (WSS) is a rare autosomal dominant disorder characterized with hypertrichosis cubiti, dysmorphic facial appearance (hypertelorism, thick eyebrows, and narrow palpebral fissures), psychomotor delay, and short stature. WSS is caused by a mutation in the KMT2A gene. The timing of secondary sexual characteristics in patients with WSS is not well known. To our knowledge, two patients (one boy and one girl) with W...

Introduction: Iodide transport in the thyroid is crucial for thyroid hormone synthesis. A homozygous loss-of-function mutation in the SLC26A4gene coding an iodide transporter located at the apical side in the thyroid follicular cells causes Pendred syndrome accompanied with goitrous congenital hypothyroidism (CH) and sensorineural deafness. However, about half of patients with Pendred syndrome demonstrate normal thyroid function. This indicates anothe...
