Turner syndrome (TS) is associated with a wide range of clinical stigmata, such as short stature, ovarian dysgenesis, delayed puberty and infertility, congenital malformations, endocrine disorders, including a range of autoimmune conditions and type 2 diabetes, and neurocognitive deficits. Morbidity and mortality are clearly increased compared with the general population and the average age at diagnosis is quite delayed. During recent years it has become clear that a multidisc...

Turner syndrome (TS) affects 25-50 per 100,000 females and can involve multiple organs through all stages of life, necessitating a multidisciplinary approach to care. Numerous important advances have been noted during recent years. These advances cover all specialty fields involved in the care of girls and women with TS. This new international guideline is based on an international effort with emphasis on 1) diagnostic and genetic issues, 2) growth and development during child...

Turner syndrome is a condition in females missing a sex chromosome (45,X) or parts of the second sex chromosome. It is considered a rare condition and associated with a range of characteristics, such as short stature, ovarian dysgenesis, delayed puberty and infertility, congenital malformations of the heart, endocrine disorders, including a range of autoimmune conditions and type 2 diabetes. Morbidity and mortality is clearly increased compared with the background population a...

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: The majority of Turner syndrome (TS) girls need exogenous estrogen treatment to induce normal uterine growth. The optimal estrogen treatment protocol has not been determined.Objective and hypotheses: To compare the effect of two different dosing regimens of oral 17β-estradiol on uterine size with the hypotheses that most girls with TS would benefit from a higher dose.Method: A double-blind 5-year randomized control...

Background: Hypospadias surgery is usually performed during infancy at which time parents act as proxy decision makers. Parental decisional regret, a common phenomenon after hypospadias surgery, may be affected by the process of informed consent where decision making between parents and healthcare provider is shared based on available evidence and individual concerns.Objective: To identify short- and long-term parental c...

Introduction: Sex chromosome abnormalities (SCAs) are genetic conditions characterized by deviations in the number or structure of the sex chromosomes, present in 1 in 400 newborns. Despite their clinical significance, many patients with SCAs are diagnosed late in life or remain undiagnosed, leading to delayed or inadequate medical intervention. Karyotyping, the gold standard for diagnosis, is unsuitable for population-based newborn screening, as it is time-co...

Background: Klinefelter syndrome (47,XXY; KS) influences neurodevelopment, resulting in a neurocognitive profile with a more pronounced impact on verbal IQ compared to performance IQ. Additionally, KS is linked to changes in the epigenome and transcriptome. The relation between these epigenetic and genetic changes and the neurocognitive phenotype has yet to be determined.Methods: We conducted a comprehensive and integrat...

Aim: Increased clinical attention toward less severe cases of congenital adrenal hyperplasia (CAH) may affect both incidence and prevalence. In this nationwide population-based cohort study, we estimate incidence, prevalence, and age at diagnosis of CAH according to subtype and sex.Patients and Methods: Individuals registered with a diagnosis of CAH during 1977 to 2018 were identified in the Danish National Patient Regis...

Background: Turner syndrome (TS) is associated with short stature, hypogonadism, autoimmune diseases and metabolic conditions. Genome-wide changes in TS affect both transcriptome and methylome. Genomic studies have primarily focused on 45,X, but only 35-45% of the TS population has 45,X, while the remaining TS have other karyotypes.Methods: We used 5 study cohorts. A “genomic cohort” of TS with 45,X karyotype...
