Klinefelter's Syndrome & mtf transexuality?
« on: August 07, 2010, 10:39:54 pm »
Hey
I was wondering if the two were related? Do you think that there are transwomen who are born with this condition in addition to Harry Benjamin Syndrome? My brother who's a medical student brought this up to me (as I am quite tall and have breast development without hormone treatment), and we were wondering if the two may be connected to each other. Have any transwomen here been diagnosed with this or does anyone have experience who could share?
Thanks!

I don't think anyone can tell you if there's a connection or not, there's never been any studies.

I can tell you that atleast one semiactive user on susans is both.

Klinefelter's is a form of intersex condition.

There are many of us here, myself included, who are both intersexed in some way, and are trans (or rather have been trans because I'm postop so I regard myself as merely having a Trans history now since, of course, I was cured by SRS).

However the two conditions are not really related as there are also many people who have one without the other.

But it is possible to suffer from both.

I read some statistics about Klinefelter people somewhere (sorry, don't remember the source).

50% of them were only into guys or were bi, and 5 or 10% had a female gender identity, some of these transitioned.

You could google "Klinefelter transsexual" (without the " ") and you will finally stumble over the statistics if you have the patience to go through several pages with search results.

And if you think you might have Klinefelter syndrome, go to a shrink/endocrinologist and get it checked up. It's not nice when left untreated as you might lack sex hormones and therefore end up with osteoporosis (brittle bones).

Hi, Charlotte:

Your brother knows his stuff.  Both Klinefelter and transsexual etiologies can, in fact, be coexistent and yet not be comorbid conditions.  In succinct nut-shell synopsis, Klinefelter's syndrome is:

Signs and symptoms
Affected males are almost always effectively infertile, although advanced reproductive assistance is sometimes possible.[7] Some degree of language learning impairment may be present,[8] and neuropsychological testing often reveals deficits in executive functions.[9] In adults, possible characteristics vary widely and include little to no signs of affectedness, a lanky, youthful build and facial appearance, or a rounded body type with some degree of gynecomastia (increased breast tissue).[10] Gynecomastia is present to some extent in about a third of affected individuals, a slightly higher percentage than in the XY population, but only about 10% of XXY males' gynecomastia is noticeable enough to require surgery.[11]

The term hypogonadism in XXY symptoms is often misinterpreted to mean "small testicles" or "small penis". In fact, it means decreased testicular hormone/endocrine function. Because of this hypogonadism, individuals will often have a low serum testosterone level but high serum follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels.[12] Despite this misunderstanding of the term, however, it is true that XXY men also have microorchidism (i.e. small testicles).[12]

The more severe end of the spectrum of symptom expression is also associated with an increased risk of germ cell tumors, male breast cancer,[13] and osteoporosis,[4] risks shared to varying degrees[14] with females. Additionally, medical literature shows some individual case studies of Klinefelter's syndrome coexisting with other disorders, such as pulmonary disease, varicose veins, diabetes mellitus, and rheumatoid arthritis, but possible correlations between Klinefelter's and these other conditions are not well characterized or understood.[citation needed]

In contrast to these potentially increased risks, it is currently thought that rare X-linked recessive conditions occur less frequently in XXY males than in normal XY males, since these conditions are transmitted by genes on the X chromosome, and people with two X chromosomes are typically only carriers rather than affected by these X-linked recessive conditions.

There are many variances within the XXY population, just as in the most common 46,XY population. While it is possible to characterise 47,XXY males with certain body types, that in itself should not be the method of identification as to whether or not someone has 47,XXY. The only reliable method of identification is karyotype testing.

Diagnosis
A karyotype is used to confirm the diagnosis. In this procedure, a small blood sample is drawn. White blood cells are then separated from the sample, mixed with tissue culture medium, incubated, and checked for chromosomal abnormalities, such as an extra X chromosome.

Diagnosis can also be made prenatally via chorionic villus sampling or amniocentesis, tests in which fetal tissue is extracted and the fetal DNA is examined for genetic abnormalities. A 2002 literature review of elective abortion rates found that approximately 50% of pregnancies in the United States with a diagnosis of Klinefelter's syndrome were terminated.[15]

Cause
The extra X chromosome is retained because of a nondisjunction event during meiosis (sex cell division). The XXY chromosome arrangement is one of the most common genetic variations from the XY karyotype, occurring in about 1 in 500 live male births.[4]

In mammals with more than one X chromosome, the genes on all but one X chromosome are not expressed; this is known as X inactivation. This happens in XXY males as well as normal XX females.[16] However, in XXY males, a few genes located in the pseudoautosomal regions of their X chromosomes, have corresponding genes on their Y chromosome and are capable of being expressed.[17] These triploid genes in XXY males may be responsible for symptoms associated with Klinefelter's syndrome.[citation needed]

The first published report of a man with a 47,XXY karyotype was by Patricia A. Jacobs and Dr. J.A. Strong at Western General Hospital in Edinburgh, Scotland in 1959.[18] This karyotype was found in a 24-year-old man who had signs of Klinefelter's syndrome. Dr. Jacobs described her discovery of this first reported human or mammalian chromosome aneuploidy in her 1981 William Allan Memorial Award address.[19]

Variations
The 48, XXYY (male) syndrome occurs in 1 in 18,000–40,000 births and has traditionally been considered to be a variation of Klinefelter's syndrome. XXYY tetrasomy is no longer generally considered a variation of KS,[citation needed] although it has not yet been assigned an ICD-10 code.

Males with Klinefelter syndrome may have a mosaic 47,XXY/46,XY constitutional karyotype and varying degrees of spermatogenic failure. Mosaicism 47,XXY/46,XX with clinical features suggestive of Klinefelter syndrome is very rare. Thus far, only about 10 cases have been described in literature.[20]

This mildly technical treatise is extracted from Wikipedia.  Anytime any of you want to know something about medical conditions and/or terms, I highly recommend Wikipedia to you.  Why?  The people who contribute these kinds of articles usually are professionals either practicing and/or researching in the medical field.  Their information is generally quite accurate, informative and complete enough for the layperson.  Nine times out of ten, this resource will be all that you need (as a layperson) to get good answers to your questions on matters medical. 

Think your bro is gonna be a really good doctor someday.  Hope you two are on good terms.  If you are, you're lucky to have somebody like that in the family. 

Good question!  Good luck!    ;)
Believe.  Persist.  Arrive.    :D

I know a few trans girls that have Klinefelters (XXY) but it's not a for sure thing, I don't think. If you have Klinefelters it doesn't mean your trans and if you're trans you don't necessarily have Klinefelters...although I don't know anyone that has it that isn't trans.....hehe. I've often wondered if I had it too.

Has anyone found any studies on this?  I too have been told that I have Klinefelter's, though it was not confirmed with genetic testing, I have all the symptoms.  My regret is that I was not given any counseling and just put on T when I was younger.
