Background: The large phenotypic spectrum of Disorders of Sex Development are caused by mutations in many different genes, but a large phenotypic spectrum of sexual disturbancies may also be seen with different mutations in the same gene.Objective and hypotheses: To report on one new mutation in the 5 alfa reductase (SRD5A2) gene, and describe the extremes of the phenotypic spectrum of 5 alfa reductase deficiency presented in two patients.<p class="a...

Background: The anogenital distance (AGD) is considered a valid marker of altered androgen action in utero. Recently, reduced AGD has been shown in males with hypospadias, cryptorchidism, reduced semen quality and infertility. It has also been proposed as a new marker to be used by clinicians when managing patients with Disorders of Sex Development. However, little normative data exist and measurement methods vary.Objective and hypotheses: We established...

Background: Reduced bone mineral density (BMD) is seen in Turner syndrome (TS) with an increased risk of fractures and osteoporosis. Body composition in TS is characterised by increased body fat (FM) and decreased lean body mass (LBM), even with a normal BMI. Oestrogen replacement therapy for attaining and preserving normal bone mass is necessary in most TS girls. There is a potential role of age-specific estrogen doses, with lower doses used in the early puberty and higher do...

Background: X-linked hypophosphatemia (XLH) are rare inheritable disorders caused by excessive renal phosphate wasting manifesting as rickets in children and osteomalacia in adults. Osteoid accumulates due to the reduced mineralization rate. Based on previous histomorphometric bone biopsy studies it the impression that XLH is a low bone turnover disease. Very little is known about the level of bone markers in XLH and the effects of conventional medical treatment with oral phos...

Background: Prader-Willi Syndrome (PWS), due to loss of expression from genes within the PWS imprinted region at chromosome 15q11.2-13, is characterized by hypotonia and feeding intolerance in infancy with later development of hyperphagia and obesity. Growth hormone improves tone, body composition, and height and can be started in infancy. Morbidity and mortality in PWS include those secondary to hyperphagia and respiratory illness as well as a 17% reported incidence of sudden...

Background: Children with GHD, in addition to short stature, may experience physiological symptoms as well as social and emotional problems. Assessing these impacts is critical for understanding the extent of GHD burden and assessing treatment benefit. Since many children initiating treatment are too young to self-report information, we must rely on adult reporters. However, according to FDA guidelines and established measure development principles, adult reporter information ...

Background: Hypophosphatemic rickets (HR) are rare, inheritable disorders caused by excessive renal phosphate wasting. Despite a generalized mineralization defect, patients with HR are reported with a lower risk of fracture.Objective and hypotheses: The aim of this study was to evaluate the effect of bone -geometry, -microarchitecture and volumetric BMD (vBMD) on the estimated bone strength in adult patients with HR using high-resolution peripheral quant...

Objectives: To present Chung-Jansen Syndrome or CHUJANS by a de novo variant in the pleckstrin homology domain-interacting protein (PHIP) gene and compare the clinical phenotype with previous case reports; ②To provide a novel genetic detection methods with whole-exome sequencing(WES) and whole genome sequencing(WGS) and Sanger sequencing for rare genetic diseases.Patients and methods: Following collecting clinical...

Introduction: I. was born at term by emergency caesarean delivery due to foetal distress, by unrelated parents. Birth weight: 2160 g (-3.18 SD), length 41.5 cm (-4.47 SD), head circumference 35.4 cm (0.57 SD). He was admitted in the neonatal intensive care unit (NICU) for the severe growth retardation associated to dysmorphic features. Neonatal screening, echocardiography and brain ultrasound normal. Karyotype: 46,XY.Case present...

Context: The early activation of the hypothalamic-pituitary-gonadal axis during infancy can be used in the evaluation of infants suspected of disorders of sex development (DSD). However, few data exists on sex-specific reference ranges for these hormones during early life.Objective: To evaluate sex-differences in reproductive hormone concentrations in serum from healthy infants in order to define sex-specific cut-off values and to apply these in infants ...
