Revisiting GDF9 variants in primary ovarian insufficiency: A shift from dominant to recessive pathogenicity?

Background: Primary ovarian insufficiency (POI) affects around 2-4% of women before the age of 40. Genetic factors play an important role in POI. The GDF9 gene has been identified as a significant genetic contributor of POI.

Biallelic FANCA variants detected in sisters with isolated premature ovarian insufficiency.

Premature ovarian insufficiency is a common form of female infertility affecting up to 4% of women and characterised by amenorrhea with elevated gonadotropin before the age of 40. Oocytes require controlled DNA breakage and repair for homologous recombination and the maintenance of oocyte integrity. Biallelic disruption of the DNA damage repair gene, Fanconi anemia complementation group A (FANCA), is a common cause of Fanconi anaemia, a syndrome characterised by bone marrow failure, cancer predisposition, physical anomalies and POI.

Shifting the landscape: Dominant C-terminal rare missense FOXL2 variants in non-syndromic primary ovarian failure etiology.

Pathogenic germline variants in the FOXL2 gene are associated with Blepharophimosis, Ptosis, and Epicanthus Inversus syndrome (BPES) in humans, an autosomal dominant condition. Two forms of BPES have emerged: (i) type I (BPES-I), characterized by ocular signs and primary ovarian failure (POI), and (ii) type II (BPES-II) with no systemic associations. This study aimed to compare the distribution of FOXL2 variants in idiopathic POI/DOR (diminished ovarian reserve) and both types of BPES, and to determine the involvement of FOXL2 in non-syndromic forms of POI/DOR.

A Human Homozygous Missense Variant Does Not Cause Premature Ovarian Insufficiency in a Mouse Model.

Disruption of meiosis and DNA repair genes is associated with female fertility disorders like premature ovarian insufficiency (POI). In this study, we identified a homozygous missense variant in the gene (c.596 A>C; p.

Very long-term outcomes of pediatric patients treated for optic pathway gliomas: A longitudinal cohort study.

Background: Optic pathway gliomas (OPGs) represent 5% of childhood brain tumors. Successive relapses lead to multiple treatments exposing to late complications.

Methods: We included patients treated at Gustave Roussy (GR) between January 1980 and December 2015 for OPG, before 18 years old and alive at 5 years from diagnosis.

Position statement on the diagnosis and management of congenital pituitary deficiency in adults: The French National Diagnosis and Treatment Protocol (NDTP).

Pituitary deficiency, or hypopituitarism, is a rare chronic disease. It is defined by insufficient synthesis of one or more pituitary hormones (growth hormone, TSH, ACTH, LH-FSH, prolactin), whether or not associated with arginine vasopressin deficiency (formerly known as diabetes insipidus). In adult patients, it is usually acquired (notably during childhood), but can also be congenital, due to abnormal pituitary development.

Impact of exenatide on weight loss and eating behavior in adults with craniopharyngioma-related obesity: the CRANIOEXE randomized placebo-controlled trial.

Importance: A major issue in the management of craniopharyngioma-related obesity (CRO) is the ineffectiveness of the current therapeutic approaches.

Objective: To study the efficacy of glucagon-like peptide-1 analogs compared with placebo in adults with obesity CRO.

Design: A double-blind multicenter superiority randomized clinical in trial in two parallel arms.

Drivers of patient and caregiver preferences for growth hormone deficiency treatments in France: a discrete choice experiment.

Introduction: To identify drivers of preference for growth hormone deficiency (GHD) treatment in French children, and their caregivers, and to quantify the relative importance of different aspects of treatment modalities using a discrete choice experiment (DCE).

Materials And Methods: Attributes characterizing GHD treatment modalities were identified through a literature review, qualitative interviews and focus groups with children, adolescents, and caregivers. A DCE questionnaire of 12 choice tasks was administered online to four groups of participants: autonomous adolescents (12 to 18 years), non-autonomous adolescent / caregiver dyads, caregivers of non-autonomous children (3 to 11 years) and autonomous children / caregiver dyads.

Stratification of the risk of ovarian dysfunction by studying the complexity of intermediate and premutation alleles of the FMR1 gene.

FMR1 premutation female carriers are at risk of developing premature/primary ovarian insufficiency (POI) with an incomplete penetrance. In this study, we determined the CGG repeat size among 1095 women with diminished ovarian reserve (DOR) / POI and characterized the CGG/AGG substructure in 44 women carrying an abnormal FMR1 repeat expansion number, compared to a group of 25 pregnant women carrying an abnormal FMR1 CGG repeat size. Allelic complexity scores of the FMR1 gene were calculated and compared between the two groups.

NOBOX gene variants in premature ovarian insufficiency: ethnicity-dependent insights.

Purpose: Premature ovarian insufficiency (POI) affects approximately 1% of women before the age of 40. Genetic contribution is a significant component of POI. The NOBOX gene was considered one of the major genetic causes of POI.

Identifying patient-related predictors of permanent growth hormone deficiency.

Objective: Isolated childhood growth hormone deficiency (GHD) can persist into adulthood, and re-testing at the transition period is needed to determine whether continued growth hormone therapy is indicated. Here, our objective was to identify predictors of permanent GHD.

Design: Retrospective single-centre study of patients with childhood-onset GHD who were re-tested after adult height attainment.

Assessment of Puberty and Hypothalamic-Pituitary-Gonadal Axis Function After Childhood Brain Tumor Treatment.

Context: Endocrine complications are common in pediatric brain tumor patients.

Objective: To describe hypothalamic-pituitary-gonadal axis (HPGA) function in patients treated in childhood for a primary brain tumor more than 5 years earlier, in order to identify risk factors for HPGA impairment.

Methods: We retrospectively included 204 patients diagnosed with a primary brain tumor before 18 years of age and monitored at the pediatric endocrinology unit of the Necker Enfants-Malades University Hospital (Paris, France) between January 2010 and December 2015.

Family building after diagnosis of premature ovarian insufficiency: a cross-sectional survey in 324 women.

Objective: The diagnosis of premature ovarian insufficiency (POI) is a traumatic event for many patients that involves poor fertility prognosis. After such diagnosis, spontaneous pregnancies are rare. The alternatives for building a family are oocyte donation, embryo donation, and adoption.

Modified-release hydrocortisone is associated with lower plasma renin activity in patients with salt-wasting congenital adrenal hyperplasia.

Objective: Poorly controlled salt-wasting (SW) congenital adrenal hyperplasia (CAH) patients often require high 9α-fluorocortisol doses as they show high levels of 17-hydroxyprogesterone (17OHP), which is a mineralocorticoid (MC)-receptor antagonist.

Design: We investigated the renin-angiotensin-aldosterone system in patients with SW-CAH receiving twice daily modified-release hydrocortisone (MR-HC, Efmody) compared with standard glucocorticoid (GC) therapy.

Methods: Data were analyzed from the 6-month, phase 3 study of MR-HC (n = 42) versus standard GC therapy (n = 41).

Treatment patterns and unmet needs in adults with classic congenital adrenal hyperplasia: A modified Delphi consensus study.

Background: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare autosomal recessive condition characterized by cortisol deficiency and excess androgen production. The current standard of care is glucocorticoid (GC) therapy, and sometimes mineralocorticoids, to replace endogenous cortisol deficiency; however, supraphysiologic GC doses are usually needed to reduce excess androgen production. Monitoring/titrating GC treatment remains a major challenge, and there is no agreement on assessment of treatment adequacy.

Fertility and pregnancy outcomes in women with nonclassic 21-hydroxylase deficiency.

Introduction: Overall fertility and pregnancy outcomes in patients with nonclassic congenital adrenal hyperplasia (NCCAH) have been poorly studied. It has been suggested that hydrocortisone (HC) may decrease the time to conceive (TTC) and the rate of miscarriage in these patients.

Objectives: To describe fertility and pregnancy outcomes in a large cohort of NCCAH women.

Normal-high IGF-1 level improves pregnancy rate after ovarian stimulation in women treated with growth hormone replacement therapy.

Objective: Growth hormone (GH) and insulin-like growth factors (IGFs) are not mandatory for reproductive life, but data suggest their synergistic action with follicle-stimulating hormone throughout ovarian folliculogenesis. We aimed to evaluate the association of IGF-1 level on clinical pregnancy rate after ovarian stimulation, with or without intrauterine insemination, in women with GH deficiency (GHD) treated with GH replacement therapy (GHRT) at conception.

Design And Methods: Data from 19 women with both GHD and hypogonadotropic hypogonadism referred to our reproductive medicine department were retrospectively collected.
