Turners Syndrome
(Webster's definition) A chromosomal disorder resulting in a syndrome
characterized by specific dysmorphic features (short stature) and organ
malformations (gonadal dysgenesis) Turner's Syndrome- (Anastasia and Rosebud's
def.) "It's something that makes me different from other people. It's
something that I'm proud of, and ya know what? I have a pretty normal
life." When I was assigned this report, I decided to do a little more than
the average person does. When I was doing all of the research, I wondered what
it would be like to have TS. Well, through the wondrous powers of the Internet,

I was able to take a peek at TS by talking to two young women who have it. What
did they have to say? Suprizingly, they were extremely open and happy. These
girls were full of life and weren't letting TS get to them. Anastasia is 11(from

Cincinnati, Ohio), and Rosebud (screen name) is 24, from Minnesota. Anastasia
was diagnosed when she was 4 months old. She commented, "It's really not
that bad once you get use to it." As a young child, she always is picked on
about her shortness. However, she wanted to make it quite clear that she was
only picked on about her shortness, and not her TS. Anastasia is in the 6th
grade, (Caucasian) and wants to become famous. She takes GH shots to help her
growth and shouted to the chat room, "I have TS...and I'm proud of
it!!" Rosebud is 24, Caucasian, and single. She was diagnosed when she was

11. She comments that, "I would have to say that I've had a pretty normal
life." Rose bud was never teased as a child or as an adult. Children don't
really know about TS, but her playmates never made fun of her. Rose also took GH
shots when she was younger to help her with the TS, but she doesn't take them
anymore Turner's Syndrome is a rare chromosomal disorder of females (1:2500)
characterized by short stature and the lack of sexual development at puberty.

H.H. Turner first described this syndrome in 1938. Other physical features may
include a webbed neck, heart defects, kidney abnormalities, and/or various other
malformations. Normally, females have two X-chromosomes. In some cases of

Turner's Syndrome, however, one X chromosomes is missing from the cells (45,X);
research studies suggest that approximately 40 percent of these individuals may
have some Y chromosomal material in addition to the one X chromosome. In other
affected females, both X-chromosomes may be present, but one may have genetic
defects. In still other cases, some cells may have the normal pair of

X-chromosomes while other cells do not (45, X/46, XX mosaicism). Although the
exact cause of Turner's Syndrome is not known, it is believed that the disorder
may result from an error during the division (meiosis) of a parent's sex cells.

In 1938 H. H. Turner first described TS. He first found out TS through sexual
infantilism, webbed neck, cubitus valgus, and shortness. Then, in 1959, Ford et
al recognized the chromosomal basis of syndrome. The clinical features are

Classic, Newborn, and Childhood/Adolescence. In the Classic, there is short
stature, gonadal dysgenesis, and lymphedema. In the Newborns, they are small for
dates, lymphedema of hands and feet, and excessive skin at nape of neck. In

Childhood/Adolescence, there is a 98% short stature, 95% gonadal dysgenesis, 82%
high palate, 80% short neck, low hairline, 78% hypoplastic, widely-spaced
nipples, 75% broad chest, cubitus valgus, nail hypoplasia, and a 70% lymphedema,
prominent anomalous ears, and excessive nevi. Ways of management are supportive,
surgery, and endocrine. For supportive, you should follow-up with ophthalmology,

ENT, dentist, orthopedics, cardiology, urology, genetic counseling. For surgery,
there is the removal of bilateral streak gonads prior to starting in

45,XO/46,XY. With endocrine there is growth, gonadal failure, fertility, and
hypothyroidism. With the growth, there is a low dose of estrogen at an early age
with slow progression to a higher dosage, and a combination of low dose
estrogen, growth hormone, and anabolic steroid. With gonadal failure, there is a
replacement with estrogen and progesterone. You must begin at the time
appropriate for teenage peers, and start with a low dose estrogen for 1-2 years
then progress to larger doses cycled with progesterone and then maintain with
the birth control pill. With fertility, there is the oocyte donation, gamete or
embryo transplant. And finally, with the hypothroidism, there is replacement
therapy. TS is a female disease and is more common that one would think.
