Objective. To evaluate differences in phenotype and other clinical features between patients who have Turner syndrome diagnosed incidentally (on the basis of a prenatal karyotype performed for reasons unrelated to suspicion of Turner syndrome, eg, advanced maternal age) or traditionally (on the basis of either a prenatal karyotype performed for abnormal ultrasound findings or a postnatal karyotype performed for clinical findings suggesting Turner syndrome). Methods. Analysis was performed on…

TLDR
Termination was the most common outcome of fetuses diagnosed antenatally with Turner syndrome, which has modified the natural history of Turner syndrome particularly in cases with Mosaic karyotype.
Turner Syndrome 2008
  • C. Bondy
  • Medicine

  • 2009
TLDR
There is an unacceptably high rate of premature mortality in adults with TS, mainly because of complications from congenital heart disease, and cardiac magnetic resonance imaging is recommended to screen for individuals at high risk for serious complications.
Diagnosis and Management of Turner Syndrome in Children and Adults
TLDR
A multidisciplinary approach addressing all aspects of their care including expert cardiological monitoring and intervention when required, access to fertility and obstetric expertise when appropriate, expert genetic counselling if indicated, and discussion of psychosocial, education, employment issues is key to the successful outcome for all women with Turner syndrome.
Recent Developments in Diagnosis and Care for Girls in Turner Syndrome
TLDR
Important developments in the area of gynecological management of girls and young women with TS are reviewed, including prognostic factors that predict spontaneous puberty and potential fertility and recent practice guidelines aimed at reducing cardiovascular risk for oocyte donation pregnancies in TS.
Incidental findings of sex chromosome aneuploidies in routine prenatal diagnostic procedures : a qualitative study on the perspectives of parents and professionals
TLDR
The attitudes of pregnant women in low risk pregnancies towards full-scale genetic testing are examined and relationships between demographic characteristics and the level of interest are explored.
Prenatally Diagnosed Turner Syndrome and Cystic Hygroma: Incidence and Reasons for Referrals
TLDR
The present study indicates the importance of cystic hygroma in prenatal diagnosis of Turner Syndrome and other aneuploidies.
EFFECTS OF KARYOTYPE VARIATIONS ON PHENOTYPE OF PATIENTS WITH TURNER SYNDROME
TLDR
It is suggested that karyotype variations might affect phenotype of Turner syndrome, and chromosomal investigation for all suspected cases of Turner Syndrome should be considered in order to approach an appropriate treatment protocol.
Turner syndrome: contemporary thoughts and reproductive issues.
TLDR
The use of the term PRIMARY OVARIAN INSUFFICIENCY (POI) for Turner syndrome leaves the door open for the occurrence of reproductive function and for the 5 to 10% of 46,XX patients who may spontaneously become pregnant.
Neoplasia in Turner syndrome: a retrospective cohort study in a tertiary referral centre in Belgium
TLDR
The overall malignancy risk was not increased, but a different pattern of occurrence is apparent, with an increased risk of CNS and skin tumours and a decreased breast cancer risk.

Delayed diagnoses of Turner's syndrome: proposed guidelines for change.
TLDR
The diagnosis of TS is often delayed and karyotype analysis should be strongly considered for those who remain above the 5th percentile for height but have 2 or more features of TS, including high palate, nail dysplasia, short fourth metacarpal, and strabismus.
Prenatal and postnatal prevalence of Turner's syndrome: a registry study
TLDR
Discrepancy between prenatal and postnatal prevalence of Turner's syndrome challenges specificity of prenatal examination in diagnosing Turner’s syndrome.
Prenatal diagnosis of 45,X/46,XX mosaicism and 45,X: implications for postnatal outcome.
TLDR
The prevalence of 45,X/46,XX mosaicism is 10-fold higher among amniocenteses than in series of postnatally diagnosed individuals with Turner syndrome, which suggests that most individuals with this karyotype escape detection and that an ascertainment bias exists toward those with clinically evident abnormalities.
The distribution of chromosomal genotypes associated with Turner's syndrome: livebirth prevalence rates and evidence for diminished fetal mortality and severity in genotypes associated with structural X abnormalities or mosaicism
TLDR
The results of review of data pertinent to the livebirth prevalence of the (apparent non-mosaic) 45,X geno-type suggest a rate of about 5.7 per 100,000 livebirths with 95% confidence limits, consistent with the direct estimate of livebirth rates.
Parental decision following prenatal diagnosis of fetal chromosome abnormality.
TLDR
It is concluded that parents do distinguish among, and respond specifically to, fetal chromosome disorders of differing severity, at least in the second trimester of pregnancy, however, parents appear more inclined to terminate all pregnancies with chromosome abnormalities when the diagnosis has been made in the first trimester.
Chromosome abnormalities found among 34910 newborn children: results from a 13-year incidence study in Århus, Denmark
TLDR
Chromosome abnormalities were found in 276 liveborn children and in 19 fetuses, who were aborted after prenatal chromosome examination, the combined incidence of sex chromosomal and autosomal abnormalities was 1 per 118 children or 8.45 per 1000 children.
Decisions following the intrauterine diagnosis of sex chromosome aneuploidy.
TLDR
It is suggested that well-informed couples, counseled by geneticists, are more likely to continue these pregnancies and the possible occurrence of SCA should be considered in preamniocentesis counseling.
[Turner syndrome].
TLDR
This work presents here a female child who classical features of Turner Syndrome, most common monosomies in live born humans.
A cytogenetic survey of 11,680 newborn infants
TLDR
The results from all the series are consistent and the combined data indicate that among consecutive liveborn babies 0.56% have a chromosome aberration detectable with non-banded techniques.
CDC growth charts: United States.
TLDR
Created with improved data and statistical curve smoothing procedures, the United States growth charts represent an enhanced instrument to evaluate the size and growth of infants and children.
