Disorders of sex development (DSD) are a group of congenital developmental disorders in which the chromosomal, gonadal, or anatomical sex is atypical. The clinical diagnosis and management of DSD are difficult and complex because of the various aetiology and diverse manifestation. The project ‘Genetics of Human Disorders of Sexual Development’ is funded by Swiss National Science Foundation and fulfilled by the University of Geneva Medical School (Switzerland), the Me...

Introduction: Interstitial deletions on the long arm of the 12th chromosome are rare and often occur de novo. These deletions have been found to be associated with mental retardation, developmental delay, growth retardation and various congenital anomalies in different studies. In studies up to date, it has been determined all interstitial 12q deletions are clustered between five regions on this chromosome (HMGA2, GRIP1, LEMD3, MSRB3, and TMBIM4). Low birth we...

Background: Ovarian sex differentiation network involves a panoply of interacting factors. Yet, no single sex-determining factor has been identified to be an equivalent of SRY or SOX9 in the testis. Recently, data suggested CBX2 as a pioneer regulator promoting testis development. In addition to its implication in ovary pathway differentiation which remains unclear.Objective and hypotheses: To deepen our understanding of the regulatory network that under...

Background: CHI is a rare condition which can be related to neurological damage due to hypoglycaemic brain injury. Long hospital admissions maybe necessary which can impact babies’ experience of posture and movement, translating to a motor delay. A physiotherapy developmental assessment is a vital part of a multidisciplinary team approach to personalising care. Assessment during admission is essential to provide appropriate developmental support, particu...

Background and Objectives: Managing type 1 diabetes (TIDM) in covid pandemic is a real challenge in resource limited countries like Pakistan. This study was aimed to determine the effects of covid 19 in managing type 1 diabetes in resource limited countries.Methods: Cross-sectional observational study, included all type 1 diabetes patients who were already enrolled in endocrine and diabetes clinic and were on regular fol...

Introduction: Kisspeptin is well known gatekeeper of puberty onset to date. However, several neuroendocrine factors are also discovered to be associated with puberty onset and, especially neuropeptide Y (NPY) and neurokinin B, participate in the neuronal network integrating reproduction. However, the interactions between neuroendocrine factors and the reproductive axis have not yet been fully explored. We report herein the expression profile of NPY gene and neurokinin B gene i...

We recently showed that Xq26.3 microduplications are associated with early childhood-onset gigantism, a condition we named X-linked acrogigantism (X-LAG). Patients with X-LAG present with mixed GH/PRL secreting pituitary macroadenomas and/or hyperplasia. The original smallest region of overlap for the microduplications included 4 coding genes, of which only one, an orphan G protein-coupled receptor named GPR101, was highly expressed in tumors. A single patient with GP...

Introduction: The Kiss1/Kisspeptin/Kiss1r system is essential for puberty onset and reproductive system development, especially in the hypothalamus. Nevertheless, Kiss1 is expressed in other organs. Additionally, serum kisspeptin has been associated with puberty. However, studies on the developmental changes in serum kisspeptin levels and its main source are limited. Therefore, the aim of this study was to evaluate the developmental ...

Background: We previously found that mast cells are present in the human adult adrenal gland with a possible role in the regulation of aldosterone secretion in both physiological conditions and aldosterone-producing adrenocortical adenomas responsible for primary hyperaldosteronism.Objective and Hypotheses: The aim of the present study was to investigate the presence of mast cells in the human fetal adrenal gland, and to provide arguments in favor of the...

Background: Mutations in POU1F1 is a rare cause of combined pituitary hormone deficiency, which commonly includes GH, TSH and prolactin deficiencies and characterised by hypoplastic anterior pituitary.Objective and hypotheses: To present a case of severe short stature and developmental delay 1.5 years old girl, who was admitted to our hospital because of short stature.Method: Hypopituitarism panel’ genes were sequence...
