Klinefelter syndrome is a genetic disorder in which the person has an extra X chromosome.
It is a male disorder and the individual has male sex organs, but many other features like small testicles, higher-pitched voice, and less musculature are seen in them along with some female features like wider hips and larger breasts.
This chromosome abnormality occurs around one in every 660 males.
This chromosomal condition causes mild to severe symptoms that appear early or later on during life.
The usual signs of Klinefelter syndrome include lack of development of sperm production by the testes, enlarged breast tissue (gynecomastia), reduced facial hair at puberty, and an increase in height.
Some people develop fertility problems due to low testosterone levels while others experience infertility without any known medical problems.
A number of studies have shown that Klinefelter syndrome affects men in three ways: mentally, physically, and developmentally/cognitively with some suffering from mild or moderate learning disabilities.
There are many famous people who had this chromosomal disorder including a few celebrities. Read on to know the top 10 most famous people with this condition:
10. Dr. Renee Richards
Renee Richards was a famous ophthalmologist who has an additional X chromosome.
He was also known to suffer from Klinefelter’s syndrome. She became famous when she tried to participate in a women’s singles tournament in 1976 but was initially barred from participating because of a new law that required female competitors to have 2 X chromosomes only.
Richards refused to take the mandatory tests. She appealed the decision and won her case, he had a briefly successful career as a tennis player after this incident, despite his condition.
The New York Supreme Court made its biggest precedent by allowing her to play a woman instead of a man, citing other cases where intersexed people were permitted their own category (such as Renee Imperato-McGinnis, who won a case in 1975 to play as a woman).
9. Caroline Cossey
Caroline Cossey (born 31 August 1954) is a former English model and an actress.
Cossey was assigned male at birth and underwent gender reassignment surgery in 1974 while serving in the British Army.
She later successfully sued the UK Ministry of Defence for wrongful dismissal due to her transsexual status, receiving one thousand pounds in damages.
Cossey came to international attention in the early 1990s when she revealed that she had been a participant in the James Bond films and posed nude for Playboy magazine’s September 1991 issue.
She underwent further sex reassignment surgery later during that decade, which also ended her career as a model.
In addition to her fame from modeling and the James Bond film appearances, Cossey has also been recognized for her work as an LGBTQ rights activist.
8. George Washington
George Washington was the first President of the United States and Commander-in-Chief of the Continental Army during the American Revolutionary War.
He also presided over the convention that drafted and approved the Constitution.
The consensus among historians is that he had Klinefelter syndrome, a genetic disorder in which an individual has an extra X chromosome.
He was famous for his peak physical health despite having chronic illnesses like smallpox (he got this in 1751 when he was two years old), pneumonia (in 1789), and tuberculosis (in 1789).
He also did not have very strong muscles and at 6 feet, 4 inches tall; he did not look like the caricature of him that was drawn later on.
7. Caster Semenya
Caster Semenya is a South African middle-distance runner and gold medalist originally referred to as an intersex athlete, but no evidence was found to support this.
She has since been allowed to compete by the IAAF without any known medical conditions.
There are no other tests that can accurately diagnose the syndrome. However, some have argued that she may have a medical condition known as “classical” congenital adrenal hyperplasia. She had Klinefelter Syndrome, but her circumstances were different because he was not allowed to compete because she was not diagnosed with it.
She still won many races despite all of the controversies about her condition, and she even defended her 800-meter title at the 2012 Olympics in London.
6. Brooke Moore
Brooke Moore is a trans woman who has been missing from her town for sixteen years.
She was born with Klinefelter’s syndrome, which is the most common chromosomal disorder associated with transgenderism.
She was assigned male at birth and went to an all-boys school. But eventually, she developed breasts and never grew Adam’s apple or facial hair.
This led to her diagnosis of Klinefelter syndrome, meaning she was born with an extra X chromosome.
5. Tom Cruise
One of Hollywood’s most famous actors has been rumored to have Klinefelter syndrome. This is a genetic disorder associated with transgenderism in which an individual has an extra X chromosome.
He was diagnosed with dyslexia as a child and has struggled with it throughout his life, but eventually found a way to overcome this issue through a proper education system.
However, there are no records of him receiving treatment for Klinefelter syndrome but rumors have circulated about him having it.
4. King Tutankhamun
King Tut was an ancient Egyptian Pharaoh who lived during the New Kingdom of Egyptian history.
He was also known as the “boy-king” because he became king at age ten and died around age eighteen or nineteen, which is young for a pharaoh.
He is well known for his golden death mask which was found in a tomb.
This has been cited as the most famous archaeological find of the twentieth century, and it included a full-sized sarcophagus that was decorated with gold.
King Tut Klinefelter syndrome was discovered after his mummified remains were studied by scientists.
According to Bernadine Paul, the king’s sculptures had “defined breasts” which resembled those of a young girl who published a remarkable correspondence in JAMA from 2013-2016 claiming that she is Pharaoh Akhenaten and not Queen Nefertiti as most historians believe her identity with certainty but simply wanting confirmation through DNA tests before engaging into more serious historical research about ancient Egypt,
Even if these details are mixed up due to lack or unclear information during the excavation process it can still come out positively for this subject because there does exist evidence accepting both sides, one stating he suffered while the other exonerates him completely given the latest discoveries!
3. Lili Elbe
Lili Elbe is a famous Danish painter and a transgender person.
She was born as Einar Magnus Andreas Wegener, but she changed her name to Lili Ilse Elvenes after transitioning from male to female.
In 1930, she became one of the first recipients of sex reassignment surgery ever done.
Before undergoing her first surgery, Lili Elbe had been told with firmness and determination that she was more female than male.
Doctors at the time diagnosed this condition now known as Klinefelter syndrome or “XXY” for short but did not know what caused it because scientists didn’t yet understand hormonal differentiation in humans back then.
Her physicians castrated Dr. Ludwig Levy-Lenz after deciding his feminine features were one reason people speculated about adding fuel onto speculation fires when they believed he might have given birth to children of different kinds depending on their sex organs during operation despite never producing any offspring himself.
However, she passed away after her third surgery in 1931.
But even though she is no longer alive today, the details surrounding her life are still fascinating.
Her brother Gerda Gottlieb was an artist as well and also had Klinefelter syndrome which led to the reasoning why Lili had this particular genetic disorder as well.
2. Jamie Lee Curtis
Jamie Lee Curtis is another famous Hollywood actress who might have Klinefelter syndrome.
Her parents gave her a unisex name since she was born during the middle of the twentieth century when more people started transitioning into different genders outside of designated sex roles.
For this reason, some people believe she had Klinefelter syndrome since she didn’t identify as a female.
Jamie Lee also doesn’t like to discuss this issue in public, and she might be trying to prevent rumors from getting out of hand.
However, her feminine looks do give away that there is something different about her compared to other people who were born with the XX sex chromosomes.
1. Adele Markham
Adele Markham is a 31-year-old woman who had Klinefelter Syndrome and had been living as a man until a stunning medical discovery revealed her true sexual identity.
For Adele, she had always felt that she was not meant to live life as a male and knew deep down that something was different about her.
When she was born, doctors told her parents she’s one of the three variants of XXY chromosomes which gave her ambiguous genitalia during puberty. But even though she was born with male sex organs, Adele describes herself as a normal girl who loves clothes and one day hopes to be married.
So It can be seen that Klinefelter syndrome is not really a condition of the past. Today, there are many celebrities with this genetic disorder.
We listed the above 10 famous people with the disorder to help raise awareness for those who may not be aware of the condition.
