Introduction: Autoimmune polyendocrinopathy syndrome (APS) is an inherited rare autosomal recessive disorder caused by mutations of the AIRE (autoimmune regulator) gene with organ-specific autoimmune destruction of several, mostly endocrine. APS patients may develop autoimmune enteropathies and other intestinal dysfunctions.Aim: We describe a case of eosinophilic ascites in a nine-year-old girl with APS.<p c...

Background: Loss-of-function variants in the NR5A1 gene are frequent causes of 46,XY differences of sex development (DSD). To date, the Human Gene Mutation Database contains 291 NR5A1 variants, most of which are missense (69%). Mouse models demonstrated the effect of loss of SF-1 on sex development, but the interactome of SF-1 is huge and an explanation for the broad phenotype is still missing. Controversies exist as: a) in vitro transactivation assays of NR5A...

Spondylo-epimetaphyseal dysplasia -ACAN (SEMD- ACAN) is a rare form of osteo-chondrodysplasia that represents a group of vertebral, epiphyseal, and metaphyseal dysplasia. This genetic condition is caused by biallelic loss-of-function mutations in the ACAN gene, which encodes for aggrecan, an essential component of the extracellular matrix in cartilage. Biallelic loss-of-function mutations in this gene result in a range of characteristic symptoms, including disproportionate sho...

Obesity—defined as excess fat mass which impacts on physical health—is a complex and multifactorial disease where numerous environmental factors (overeating and/or reduced physical activity) act in concert with genetic factors. Understanding molecular mechanisms of obesity has rapidly improved in recent years due to the development of faster, more specific genetic screening tools (1). Rare genetic obesities are distinguished from more-common polygenic obesities where...

Background: Adrenocortical tumors (ACT) are rare in children. Mostly occurs in younger age, before 4 years and predominantly in girls. ACT represents 1.3% of all carcinomas in paediatric age group and 0.2% of all pediatric neoplasms.Case report: 14 month old girl presented with signs of progressive hirsutism started first few months of life. She was referred to our clinic due to suspect diagnosis of virilizing CAH. Physical exams showed virilization in c...

Objectives: Familial hypocalcemia is a rare autosomal dominant disease characterized by hypercalciuric hypocalcemia. The disorder is caused by heterozygous mutation in the CASR gene that encode a calcium-sensing receptor in parathyroid glands and kidney tubules.Clinical case: The boy was born at term from non-consanguineous parents with normal length and weight. On the second day of life he was admitted to an intensive care department with convu...

Background: Van Wyc-Grumbach syndrome is a rare presentation of long standing pre-pubertal hypothyroidism characterized by bilateral multicystic ovaries, vaginal bleeding and delayed skeletal growth in case of female.Case Presentation: we present a clinical course, diagnosis and management of a case of Van Wyc-Grumbach syndrome in a 10-years old Egyptian counselled for recurrent vaginal bleeding and pubertal advancement for age. She was ...

Background: Hyperthyroidism is rare in childhood and adolescence and Graves’ disease accounts for approximately 96% of pediatric cases of thyrotoxicosis.Case Report: A 12-year-old girl, with no relevant family or personal history, was examinated for a thyroid mass noticed a few days before. She also reported excessive sweating of the hands and mild psychomotor agitation. Clinical examination revealed, in addition to the right thyroid mass, other sig...

Background: In our center for adults with rare genetic syndromes, we see adolescents and young adults with overgrowth syndromes, among others. In our 'general endocrinology' outpatient clinic, we also see patients with overgrowth, but in these cases the overgrowth is due to excess of growth hormone (GH). Our clinical impression is that the differentiation between the two is often challenging. Therefore, we believe it is important to emphasize the dif...

Background: Pseudoisodicentric X chromosomes with an Xq deletion (46,X,idic(Xq)) are rare. Most cases are mosaic, the other cell line being 45,X. Nonmosaicism is rare. Phenotype is characterized by the resultant of the X deletion. Variations from short to tall stature can occur and premature ovarian failure is a common feature.Case presentation: A 16 year old girl was referred to our clinic with primary amenorrhoea. She ...
