Purpose: To assess the prevalence in 2017 and elucidate the well-being of youngsters with gender dysphoria.Background: Gender dysphoria is described as a strong and persistent feeling of being born in the wrong sex. Often the feeling is associated with impaired ability to function in everyday life, found in children, adolescents and adults. For adolescents with gender dysphoria, puberty is an additional mental strain that can lead to depression, anxiety ...

Introduction: The umbrella term disorders of sex development (DSD) encompass a conglomerate of different genetic conditions affecting gonadal and adrenal function. Access to specialized health care and dissatisfaction with medical and psychosocial care is an issue for many adult patients. However, it is not evident which type of health care meets the needs of care seekers with DSD.Patients and methods: The European multidisciplinary outcome study dsd-LIF...

dsd-LIFE is a comprehensive clinical outcome study investigating medical, surgical, psychosocial and ethical issues to improve treatment and care of patients with the different diagnoses included in the umbrella term disorders/differences of sex development (dsd). The multidisciplinary dsd-LIFE consortium consists of 15 experienced European scientists in the areas endocrinology, psychology, surgery, gynaecology, urology and ethics. The fields of investigation of dsd-LIFE are H...

Background: Ullrich-Turner-Syndrome is usually characterized by typical morphological features. Short status, delayed bone age in childhood and gonadal dysgenesis with delayed or lacking pubertal development, amenorrhoea and infertility. Other symptoms like thyroid dysfunction, heart defects, diabetes, behavioural or learning problems vary. The genotype/phenotype correlation may be poor. Especially in UTS mosaicism, spontaneous puberty may occur.Objectiv...

Background: Hypoglycemia is the most common and most feared complication of insulin treated diabetes. Though mostly asymptomatic, nocturnal hypoglycemia can be fatal in rare cases: sudden nocturnal death is more frequent in diabetic patients than in others. It is postulated that hypoglycemia related QTc prolongation contributes to cardiac arrhythmia and can lead to dead in bed.Objective: To evaluate influence of nocturna...

Background: Rare congenital conditions with incongruence of chromosomal, gonadal, and phenotypic sex have been summarized as disorders of sex development (DSD). Included in DSD are conditions with diverse genetic etiology, varying levels of prenatal androgen effects, phenotypes, and subsequently, different medical treatments. Quality of life (QoL) and psychological wellbeing are indicators of successful psychosocial adaptation to the conditions. Studies addressing these issues...

Human growth is a complex trait. A considerable number of gene defects have been shown to cause short stature, but there are only few examples of genetic causes of non-syndromic tall stature. Besides rare variants with large effects and common risk alleles with small effect size, oligogenic effects may contribute to this phenotype. Exome sequencing was carried out in a tall male (height 3.5 SDS) and his parents. Filtered damaging variants with high CADD scores were validated b...

Background: The steroidogenic Factor 1 (SF1, NR5A1) is one of the key factors involved in gonadal and adrenal development and steroidogenesis. Until now, over 50 mutations were described in different phenotypes of XY disorders of sex development (DSD) such as complete gonadal dysgenesis, severe and mild partial gonadal dysgenesis, hypospadias, infertility and bilateral anorchia. So far, no genotype-phenotype correlation could be demonstrated.Objective an...

Background: Low birth weight, unfavourable intrauterine conditions, and post-natal catch-up growth are associated with a subsequent impact on growth, pubertal development, and metabolic disturbances later in life. Although the start of puberty is genetically determined it might be altered due to environmental influences.Objectives: In a longitudinal study (birth to final height) we observed growth and pubertal development of genetically identical twins b...

Background: 49,XY gonadal dysgenesis (GD) is a very rare disorder of testes development with an incidence of 1:50–100 000. MAP3K1 is a MAPK that mainly regulates the MAPK pathways. High Map3k1 expression was found in female and male mice gonads at 13.5 dpc. In 2010, MAP3K1 mutations were identified in two families with complete and partial XY GD and in two unrelated sporadic cases with complete XY GD (Pearlman 2010 AJMG). Recently, four additional mutations (four out of 4...
