Presentation
Two years later she presented with sings of hypocorticisam (artralgia, hyperpigmentation, fatigue and hypotension) and low corisol level, but normal electrolyte level, hydrocortisone substitution was started. PTH was in referent range. [endocrine-abstracts.org]
However, the classic genetic change is not present in all cases. [radiopaedia.org]
Other health problems may also be present involving the heart or renal system (i.e., kidneys). Many problems affecting girls with Turner syndrome can be managed or corrected with appropriate medical treatment. [checkorphan.org]
During childhood, girls with Turner syndrome usually present with short stature. [3] In older adolescents and adults, presenting symptoms usually involve issues of puberty and fertility as well as short stature. [emedicine.medscape.com]

None of the patients studied thus far with FISH have exhibited a Y-chromosome cell population. [mayoclinic.pure.elsevier.com]
The FISH results for 12 of the 19 cases were uniformly monosomy X. Table 2 Interphase FISH analysis results for 19 patients with a 45,X G-banded karyotype a Fig. 1 a, FISH using an X centromere probe (DXZ1). [nature.com]
Results Ninety five cases with 45,X cell line found, of which 60 were detected by karyotyping, 4 by FISH for sex chromosomes, and 31 by both karyotyping and FISH. [molecularcytogenetics.biomedcentral.com]
These can be identified by chromosomal analysis and molecular cytogenetic techniques such as Fluorescent in Situ Hybridization (FISH) and Microarray, which have enormously expanded in recent years. [books.google.com]
- Weakness
Women with Turner syndrome are also at increased risk of developing weak, brittle bones (osteoporosis). Learning disabilities. Girls and women with Turner syndrome usually have normal intelligence. [mayoclinic.org]
Osteoporosis —Women are more likely to have weak or thin bones due to a deficiency of estrogen. This may result in curvature of the spine, height loss and an increased chance of fractures. [clevelandclinic.org]

Isochromosomes (i) are structurally abnormal chromosomes comprised of two identical arms: either two short arms are two long arms. [alpfmedical.info]
Workup
See Workup for more detail. Management Patients with Turner syndrome require screening for commonly associated chronic diseases. [emedicine.medscape.com]
Many individuals with a diagnosis of Turner syndrome undergo a complete cardiac workup to assess the structure and function of the heart. This will include an echocardiogram. [rarediseases.org]

Prognosis
Overall prognosis very variable is dependent on associated anomalies. [radiopaedia.org]
Prognosis Despite the high risk of miscarriage and stillbirth, the overall prognosis for a baby with Turner syndrome is far from dismal after birth. [verywell.com]
Prognosis The prognosis of Turner syndrome depends partly on whether the patient has monosomy X, a damaged second X chromosome, or mosaic Turner syndrome. [encyclopedia.com]
The long-term outlook ( prognosis ) for people with Turner syndrome is typically good. [rarediseases.info.nih.gov]
Prognosis Most children with Turner syndrome can live relatively normal lives. The prognosis for a person with Turner syndrome is dependent on the other associated conditions that may be present. [healthofchildren.com]
Etiology
Monosomy X is the most common etiology, classically presenting with hypoestrogenemia and short stature. We present two cases of partial X chromosome deletions that do not reflect the typical phenotype of TS. [readbyqxmd.com]
C 11 Etiology Turner syndrome is caused by a reduced complement of genes that are typically expressed from both X chromosomes in females. [aafp.org]

Prevention
Hummel, M.D., a nationally recognized Fertility Specialist, states "A significant number of miscarriages can be prevented. A thorough fertility evaluation should give all couples options to maximize a full term pregnancy." [books.google.ro]
Prevention - Monosomy X There is no cure for Turner syndrome; however, many of the more serious problems can be treated. [checkorphan.org]
Prevention Since Turner syndrome is thought to be caused by a random genetic mutation rather than an inherited genetic defect, there is no way to prevent it. [encyclopedia.com]

Early preventive care and treatment are also essential. [13] Growth hormone therapy In childhood, growth hormone therapy is standard to prevent short stature as an adult. [14, 15, 16] The ideal age for initiating treatment has not been established; taller [emedicine.medscape.com]
