Turner syndrome: Causes and Symptoms- Dr. Srinivasa Murthy C L
It is a chromosomal condition that alters development in females. Women with this condition tend to be shorter than average and are usually unable to conceive a child. Because of an absence of ovarian function. This condition occurs in about 1 in 2500 female births worldwide but is much more common among pregnancies that do not survive to term.
It is a chromosomal condition related to the X chromosome. It is not yet determined which genes on the X chromosome are responsible for most signs and symptoms of Turner syndrome.
- Girls who have Turner syndrome are shorter than average. They often have normal height for the first three years of life, but then have a slow growth rate. At puberty, they do not have the usual growth spurt.
- Non-functioning ovaries are another symptom. Normally a girl's ovaries begin to produce sex hormones at puberty. This does not happen with most girls who have Turner syndrome. They do not start their periods or develops breasts without hormone treatment at the age of puberty.
- Girls with this syndrome may have frequent middle ear infections.
- An especially wide neck and a low or indistinct hairline.
- A broad chest and widely spaced nipples.
- A heart murmur, sometimes associated with narrowing of the aorta.
- A tendency to develop high blood pressure.
- Minor eye problems.
- Scoliosis occurs in 10 percent of adolescent girls.
- Osteoporosis can develop because of a lack of oestrogen, but this can largely be prevented by taking hormone replacement therapy.
- Physical features are observed such as webbed neck, a broad chest and widely spaced nipples.
- The two main clinical feature of Turner syndrome are short stature and the lack of the development of the ovaries.
- Diagnosis is confirmed by a blood test, called a karyotype. This is used to analyze the chromosomal composition of the female.
There is no cure for Turner syndrome, but many associated symptoms can be treated.
- Growth hormone injections are beneficial in some individuals with Turner syndrome.
- Oestrogen replacement therapy is usually started at the time of normal puberty, around 12 years to start breast development.
- ENT specialist may be involved in caring for hearing loss issue.
