A rare case of a 4-year-old boy with a SRY-positive 45, X karyotype was presented. Family history of the child was not remarkable. His height and weight were -2.1 SD and -1.4 SD, respectively. Physical examination revealed a well-developed penis with hypospadias. His right testis was in the scrotum and the left testis was not palpable. In previous inguinal exploration recordings, unilateral testicular agenesis on the left side were noted. The right testis was biopsied and prep...

Background: Craniopharyngioma is a non-malignant, embryological brain tumour in the sellar and parasellar region. Hypothalamic damage is common and accompanied by development of obesity in at least 50% of cases. Mechanisms underlying hypothalamic obesity in craniopharyngioma patients however remain unclear and treatment options are invasive and limited. This feasibility study included a novel application of functional neuroimaging, an established method in obe...

Background: Phosphoglucomutase 1 (PGM-1) deficiency is a congenital disorder of glycosylation caused by an impairment of glucose-1-phosphate and glucose-6-phosphate interconversion.The clinical phenotype of PGM1 deficiency is variable and includes several endocrine manifestations such as recurrent hypoglycemia and short stature, which may be associated with the decreased levels of growth hormone (GH), insulin like growth factor-1 (IGF1) ...

Background: Central precocious puberty (CPP) is a premature activation of the hypothalamic-pituitary-gonadal axis. One of its negative effects is lower final adult height (FAH) due to premature epiphyseal closure. GnRH analogues act by desensitizing GnRH receptors and stopping the progression of puberty and prolonging growth period.Objectives: We aimed to evaluate the effect of the GnRH analogue on FAH and identify facto...

Introduction: The 46,XX testicular disorder of sex development (DSD) is a rare genetic condition and clinical phenotype shows complete sex reversal from female to male. The sex-determining region Y (SRY) gene can be identified in most 46,XX testicular DSD patients, but approximately 20% of patients are SRY-negative. We report a 1.3 -year old SRY/negative 46,XX boy with complete sex reversal caused by SOX3 duplication.Case report:...

Introduction: Hypopituitarism is the partial or complete insufficiency of a single or multiple pituitary hormones. The clinical manifestation of hypopituitarism varies depending on the number and severity of hormone deficiencies. Familial cases are rare, compared to the sporadic ones. Its estimated incidence is between 1:4000-1:10000 live births.Case report: We report the clinical case of familial hypopituitarism in a fa...

Background: TransCon hGH is a sustained-release prodrug in development as a long-acting GH for children with growth hormone deficiency (GHD). TransCon hGH consists of a parent drug, growth hormone (hGH; somatropin), that is transiently bound to a carrier via a TransCon linker. The carrier extends hGH circulation time in the body and fully active hGH is released over one week at physiologic pH and temperature. Unlike other molecules in development, TransCon hGH...

In the typical developing gonad, cells with XY chromosomes become masculinised into Sertoli cells, leading to the development of the bipotential gonad into testes. Disruptions to sex determining genes and transcription factors, or XX chromosome complement, typically leads to failure of Sertoli cell development. In the study of sex determination, upregulation of specific genes in animal models has sucessfully led to male factor expression in XX cells in some animals but not in ...

Sex differentiation and development are complex processes reflecting the precise spatiotemporal expression of specific genes and interactions among gene products. In some instances, peripheral blood karyotype diverges from anticipated findings based on phenotypic features. Ascertaining for chromosomal mosaicism aids the shared decision-making discussions with families and other health care providers. We have investigated for sex chromosome mosaicism in 13 patients by using flu...

Background: Mc Cune Albright (MAS), is a rare genetic disease clinically defined by bone fibrous dysplasia (BFD), café au lait skin spots and at least one hyperfunction endocrinopathy. Growth Hormone (GH) excess has been described in 20% of patients usually accompanied by hyperprolactinemia (80%). As reported in literature GH hypersecretion is allways associated with craniofacial BFD, macrocephaly and is also accompanied by higher risk of systemic...
