Background: Cytochrome P450 oxidoreductase (POR) deficiency (PORD) is a form of congenital adrenal hyperplasia (CAH) and results in steroid-production loss from cytochrome P450 proteins. Mutations in POR cause mild to severe forms of CAH with/without bone malformation symptoms resembling Antley-Bixler syndrome. We report a novel POR Arg550Trp mutation identified in a 46,XX patient with signs of aromatase (ARO) deficiency. Child (first pregnancy) and mother pr...

Background: AuxoLog is a validated computer program that evaluates auxologic parameters comparing them with the Spanish growth charts. It also allocates subjects to the corresponding pubertal development group.Objective: To assess the evolution of auxological parameters in GH deficient (GHD) pre pubertal children treated with Omnitrope for a minimum of 2 years prior to puberty.Method: This study is non-interventional, retrospective...

Background: Loss-of-function mutations in the imprinted gene MKRN3 represent the most common known genetic defects associated with central precocious puberty (CPP). The penetrance of these mutations remains to be established. To date, all reported individuals with MKRN3 mutations were already in puberty or postpubertal and were identified retrospectively.Objective and hypotheses: To report the first case of a prepubertal child with an MKRN3 muta...

Background: Androgen insensitivity syndrome in its complete form (CAIS) is a disorder of hormone resistance characterised by a female phenotype in an individual with an XY karyotype and testes producing age-appropriated normal concentrations of androgens. Pathogenesis is the result of mutations in the x-linked androgen receptor (AR) gene, which encodes for the ligand-activated AR. We report the clinical, biochemical and molecular features of two affected sisters in whom a nove...

Mosaic variegated aneuploidy (MVA) syndrome represents a rare autosomal recessive disease characterized by aneuploidies with gain and loss of multiple chromosomes. We describe case of two Moroccan brothers with MVA2, due to CEP57 mutations. Patients are 17 and 13-year-old male siblings of a Moroccan healthy consanguineous couple. Oldest brother was delivered at 35 gestational weeks after IGR diagnosis, small for gestational age (SGA, 1300 grams, -3 SDS). Younger patient’...

Six-year-old female, diagnosed with GH deficiency at another Center (H: -3.13SDS; H peak with clonidine 5.7ng/mL, with insulin 1.2ng/mL). Brain MRI at diagnosis: small pituitary gland, ectopic neurohypophysis, normal stalk, right internal carotid artery aplasia. At 10 years onset of polyuria-polydipsia syndrome (PPS) (4L/day–154ml/kg/die); mood disorders and ADHD diagnosis were also reported. A fluid deprivation test was performed, lasting 22 hours (pre: S-Osm 275mOsm/L,...

Although craniopharyngiomas are low-grade tumours, long-term survivors frequently suffer from severe morbidity due to hypothalamic lesions, such as hypothalamic obesity, that is largely resistant to lifestyle modification and pharmacotherapy. We investigated the efficacy of bariatric surgery in two patients with craniopharyngioma-related hypothalamic obesity during 18 months of follow-up. Patient n1, diagnosed with craniopharyngioma and treated with complete surgical excision ...

A 5-years-old boy was admitted because of polydipsia and polyuria. His family history was unremarkable. After water deprivation test (10h), laboratory test showed high levels of serum sodium (150.1 mmol/L), low urine osmolarity (88 mOsm/kg) and high serum osmolarity (301 mOsm/kg) consistent with the diagnosis of central diabetes insipidus (CDI). He started therapy with oral desmopressin with clinical improvement. Brain MRI revealed pituitary stalk thickening (3 mm), no hyperin...

Background: The SCOPE French retrospective study follows children affected with growth hormone (GH) disorders treated with recombinant human GH (r-hGH) therapy via the easypod® connected injection device for up to 5 years.Aim: To show the results from an interim analysis of the SCOPE study analysing adherence to r-hGH therapy in a real-world setting and its effect on catch-up growth.Met...

Background: Congenital hypopituitarism (CH), involving deficiencies in one or more anterior pituitary hormones, is rarely observed in combination with severe joint contractures, termed arthrogryposis. Schaaf-Yang syndrome (SHFYNG), which has phenotypic overlap with Prader-Willi syndrome, may be associated with arthrogryposis. L1 syndrome, a group of X-linked disorders including hydrocephalus and spasticity of the lower limbs, may also present with generalized contractures in r...
