An absence of sexual maturation associated with growth hormone deficiency or Turner syndrome affects both physical development and social functioning.
Is Turner syndrome a form of retardation?
Unlike some other genetic conditions, Turner Syndrome does not cause mental retardation or decreased intelligence. However some girls with Turner Syndrome have learning disabilities, especially in areas involving spatial skills, such as math.
What is Turner’s syndrome classified as?
Turner syndrome is a genetic disorder affecting girls and women. The cause of Turner syndrome is a completely or partially missing X chromosome. Turner syndrome symptoms include short stature and lack of breast development and periods. Treatment for Turner syndrome may include hormone therapy.
What type of abnormality is Turner syndrome?
Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.
Are babies with Turner syndrome small?
Turner syndrome (TS or monosomy X) is a genetic disorder that occurs in girls. It causes many traits and problems. Girls with TS are shorter than most girls. They don’t go through normal puberty as they grow into adulthood.
Why does Turner syndrome only affect females?
The condition only occurs in females. Most commonly, a female with Turner syndrome has only 1 X chromosome. Others may have 2 X chromosomes, but one of them is incomplete. Sometimes, a female has some cells with 2 X chromosomes, but other cells have only 1.
Is Turner syndrome recessive or dominant?
Turner syndrome only occurs in females. Noonan syndrome, sometimes inappropriately called male Turner syndrome, can occur in males or females. It is an autosomal dominant genetic disorder and is not a chromosomal disorder.
Is Turner’s syndrome genetic?
Most cases of Turner syndrome are not inherited. When this condition results from monosomy X , the chromosomal abnormality occurs as a random event during the formation of reproductive cells (eggs and sperm) in the affected person’s parent.
Can a woman with Turner syndrome get pregnant?
It is caused by a random error that leads to a missing X chromosome in the sperm or egg of a parent. Very few pregnancies in which the fetus has Turner Syndrome result in live births. Most end in early pregnancy loss. Most women with Turner syndrome cannot get pregnant naturally.
What genetic error causes Turner syndrome?
Turner syndrome is caused by partial or complete loss (monosomy) of the second sex chromosome. Chromosomes are found in the nucleus of all body cells. They carry the genetic characteristics of each individual and they come in pairs.
Can males have Turner syndrome?
Turner syndrome, characterized by the presence of a monosomy X cell line, is a common chromosomal dis- order. Patients with Turner syndrome are usually phenotypically female, and male cases are rarely reported.
Can Turner syndrome be detected before birth?
Turner syndrome may be suspected by prenatal cell-free DNA screening or certain features may be detected on prenatal ultrasound screening. Prenatal diagnostic testing can confirm the diagnosis.
Can Turner syndrome be misdiagnosed?
The discrepancies between the blood and skin karyotypes found in our patients mean that previous cases of Turner’s syndrome have been undiagnosed or misdiagnosed. We suggest that in some cases of Turner’s syndrome the abnormal cell lines die out in the bone marrow, thereby leaving the 46, XX cell line.
Do Turner’s syndrome have ovaries?
Girls who have Turner syndrome don’t have typical ovarian development. Because the ovaries are responsible for making the hormones that control breast growth and menstruation, most girls with TS won’t go through all the changes associated with puberty unless they get treatment for the condition.
Does Turner’s syndrome have uterus?
Even though many women who have Turner have non-functioning ovaries and are infertile, their vagina and womb are totally normal.
Can you have mild Turner’s syndrome?
There are various signs and symptoms of Turner syndrome , which can range from very mild to more severe. Short stature is the most common feature and usually becomes apparent by age 5. In early childhood, frequent middle ear infections are common and can lead to hearing loss in some cases.
