If you read last week's article, you might have remembered
me mentioning a name of a genetic disorder called Haemophilia. This horrific
condition once played absolute havoc with several European royal families and
can be judged as partially response for the downfall of the Russian
Empire.
So, bit of a background about Haemophilia. This disorder
affects the body's ability to make blood clots- or scabs. Without blood clots,
bleeding will continue. Bleeding inside joints or inside the brain can result
in seizures and death.
The two main types of haemophilia are haemophilia A, caused
by low amounts of clotting factor VIII, and haemophilia B, which is caused by
low levels of clotting factor IX. Both of these clotting factors are
essential for stopping bleeding and are proteins coded for by genes located on
the X-chromosome. Haemophilia arises when these genes are non-functional. As
the genes are located on the X-chromosome, this means both forms of Haemophilia
are X-linked. For those who didn't read my article this week, this is a form of
inheritance that involves the sex chromosomes.
So going off on a bit of a tangent, the sex chromosomes are
the X chromosomes and the Y chromosomes. Every person inherits one sex
chromosome from each parent. If someone inherits one X chromosome from one
parent and an X chromosome from another parent, they are female. If they
inherit an X chromosome from one parent and a Y chromosome from another parent,
they are male. As such, a person can either get an X or a Y chromosome from
their father, but only an X from their mother.
As women have two X chromosomes, this means that they would
have two copies of the Factor VIII and Factor IX genes. But men would only have
one copy. That means that if a man has a non-functional factor VIII or
factor IX gene, they would not be producing any factor VIII or factor IX,
giving them haemophilia. In females, they would need both copies of the factor
VIII or Factor IX to be non-functional to give them haemophilia. If only one of
their copies was mutated and non-functional, they would have another copy
producing the clotting factors. This means that they would be a carrier of the
mutations and can pass this on to their children.
So, these days, haemophilia is reasonably well managed.
Clotting factors can now be injected to replace the missing clotting factor in
the blood and prophylaxis to prevent bleeding can also be given. People
with the disease often live to a near- normal life expectancy.
But let’s cast our mind back to the late 1800's and early
1900's where haemophilia wasn't well managed. There was next to nothing that
doctors could do other than give pain relief and advise rest. Aspirin could be
offered- but doctors, due to lack of understanding of haemophilia, did not know
this was one of the worst things you could actually do. Aspirin thins the blood
making the bleeding much worse.
In 1904, Tsarevich Alexi Nikolaevich, the heir to the
Russian Empire was born in St Petersburg. At this time, Russia was a very
powerful empire that spanned from the Arctic Ocean to the Black Sea in the
south, Central Asia and some parts of Northeast Asia. The Russians were ruled
by an absolute monarch - the Tsar. By 1897, the population had reached 125.6
million. 38% of this would have been serfs- a kind of slave with limited rights
until their emancipation in 1861.
Alexei, 1916
After the birth of four girls who couldn't inherit (yes, I
know but it's the 1900's), Tsar Nicholas and his wife Alexandra were beyond
desperate for an heir. So, when Alexei was born, there was widespread joy
around St Petersburg.
Initially, the child seemed healthy, weighing 11 pounds at
birth. But after they cut his umbilical cord, his navel continued to bleed and
did not clot. Tsar Nicholas reflected that in 48 hours Alexei had lost '1/8 to
1/9 of the total quantity' of his blood. This child has been so longed
for and desired that it was devastating when the child was found to have
haemophilia B to such a severe extent that trivial injuries such as a bruise or
a cut were life-threatening. From the age of five, Alexei had two navy sailors
accompanying him at all times to prevent any injuries. The nature of his
illness was kept secret, leading to mass speculation.
Now, this is when a certain person called 'Rasputin' (Ra Ra
Rasputin, Lover of the Russian Queen... Thank you Boney M!) enters the scene.
So those who are unfamiliar with the lyrics of Boney M and the general history,
Rasputin was an apparent holy man and mystic. He gets quite a bit of a
following in St Petersburg and many of his followers are rather influential.
Ultimately, he gets popular amongst the aristocracy who are apparently curious
about the occult and the supernatural.
Grigori Rasputin, c.1910s
So, Alexandra is desperate to help her son, and this leads to her
crossing paths with Rasputin. She and Nicholas first meet Rasputin in 1905 and
meet him again in July and October 1906. It's unclear when the Tsar and Tsarina
first became convinced that Rasputin could heal the Tsarevich but there are two
records about Rasputin healing Alexei successfully.
In 1907, Alexei fell over, damaging his leg and triggering
an internal haemorrhage. There was nothing doctors could do and the child was
left racked in pain, feverish and his leg swollen. Rasputin was asked by
Alexandra to pray over Alexei. Rasputin did so and soon after he left, the
swelling in Alexei's leg went down, and the next day, Alexei's fever had
broken.
In 1912, Alexei jumped into a rowboat and hit his groin. A
large bruise appeared in minutes but started to reduce in size. It's believed
that the bruise was a hematoma- a large collection of blood outside of a blood
vessel. This is different to a bruise- which is a smaller amount of blood
leaking from smaller capillaries. A few weeks later, Alexei and his mother were
riding in a carriage. The juddering of the carriage is believed to have caused
the hematoma to rupture. This caused haemorrhages in his thigh and abdomen. For
11 days, Alexei screamed in pain, had a dangerously high fever and received the
last sacrament on the 8th of October. Alexandra asked Rasputin for help, and
received a telegram from him, reassuring her that the 'little one' would not
die and telling her not to let the doctors 'bother him'. Amazingly,
Alexei started to recover. His temperature dropped and the hematoma
disappeared.
Rasputin's apparent heeling has been the subject of a lot of
a speculation. One theory is that he used hypnosis or administered certain
herbs. One theory is that the doctors were giving Alexei aspirin, and Rasputin
praying over the boy and stopping the doctors from 'bothering' him was
preventing the doctors from administrating it. Rasputin was assassinated
in 1916 by a group of noblemen who wished to end his influence (in the words of
the iconic Boney M.... Ra-Ra-Rasputin, Russia's greatest love machine. And so,
they shot him 'til he was dead.).
Eventually, the Russian revolution breaks out and sadly,
Alexei is killed alongside his father, mother and his four sisters. He was 13
years old. In the months leading up to his death, Alexei was reliant on a
wheelchair after several haemorrhages. Now, I'm not trying to downplay the
actions of his murderers but it is possible that Alexei might not have made it
to adulthood and even if he had, he may have died young and would have been
left immobile for the rest of his life.
Now, how exactly did Alexei actually inherit the mutated
gene for Haemophilia?
Well, the answer is, if you are unfamiliar with royal
lineages, somewhat surprising. The source of the haemophilia mutation can
be traced back, though Alexei's ancestors, to a certain British ruler.... Queen
Victoria. How is the Russian royal family remotely linked to the British Royal
family? Again, that comes back to Queen Victoria and the number of children and
descendants she produced. Queen Victoria was known as the 'grandmother of
Europe' as so many of her children and grandchildren married into various royal
families around Europe.
Queen Victoria, 1882
Now we can work out that the mutation did not come from
Alexei's father. He did not have Haemophilia himself and because he would have
had only one X chromosome, he could have passed it on. This means that Alexei
could only have got the mutation from his mother - Alexandra
Feodorovna.
Born Alix of Hesse, Alexandra was born to Louis IV Grand
Duke of Hesse and Princess Alice of the United Kingdom- the second daughter of
Queen Victoria. As Louis did not have haemophilia, the mutation could not have
possibly come from his side of the family. This meant it had to come from Alice
and her mother Queen Victoria.
Alexandra Feodorovna, 1908
It's believed that it was a random mutation, where the DNA
coding for a gene is spontaneously changed. In this case, a random change must
have altered the DNA coding for the Factor IX gene stopping the protein being
produced.
But how were we able to conclude that Queen Victoria was the
source of the mutation and not her own ancestors? Well, there was no
record of the disorder appearing in her family tree at all before her. As the
disorder is X-linked dominant, if Queen Victoria was not the source, there
would have been records of her male ancestors having the illness. Also making
it likely that Queen Victoria was the source is the age of her father when she
was born. Paternal age is known to increase the chance of random and spontaneous
mutation, and Prince Edward was 51 years old.
So, was Alexei seriously unlucky being the only descendent
of Queen Victoria with Haemophilia?
After all, Alexandra had two X chromosomes with only one
being mutated. That meant that her child could have inherited the unmutated
version, meaning there would have only been a 50% chance that her male children
would have had Haemophilia. The same odds would have been in place for any
other female child or grandchild of Queen Victoria who had inherited the
mutated gene from her.
But as it happens, no. Alexei may have been the most high
profile case of haemophilia- maybe due to the Russian Revolution and Rasputin,
but he was not by far the only case. In fact, haemophilia tore through several
royal families, making its way into the Spanish, German and French royal
families as well as the English royal dynasty. It was actually known as the
'Royal Disease'.
Queen Victoria's own son Prince Leopold had haemophilia. He
suffered from recurrent joint pain and died from a cerebral haemorrhage after
slipping in Cannes. He was 30 years old. He fathered a son who inherited his Y
chromosome and as such escaped the disorder. His daughter Alice however was a
carrier. For a male and female whose father has haemophilia and mother is not a
carrier, these are the only possible outcomes. Her son Rupert also inherited
the disorder and died at the age of 20 from an intracerebral haemorrhage. He
had no children.
Queen Victoria's daughters Princess Alice and Princess
Beatrice were carriers and gave the gene to their children - Princes Freidrich
and Leopold respectively. Prince Freidrich- the older brother of
Alexandra Feodorovna. died after a bad fall. He was two. Prince Leopold
died at the age of 32 during a hip operation. He had no children. Princess
Alice also passed on the gene to her grandson Henry though her daughter Irene;
he died at four years old after a head injury. Irene also had a child
called Waldemar. He died at the age of 56 due to a lack of blood transfusion
facilities at a clinic. Of all the descendants of Queen Victoria suffering from
haemophilia, he lived the longest number of years. He died in 1945, compared to
his brother who died in 1904. This goes to show how the management of
haemophilia was starting to improve. Princess Beatrice also had two
grandchildren with the disorder Alfonso and Gonzalo, sons of her daughter
Victoria Eugenie. Alfonso died at the age of 31 of internal bleeding after a
car crash, whilst Gonzalo died at 19, also in a car crash. He was the
last descendent to be born with the disorder, although the last descendent to
die was Waldemar.
Alexei's sisters Olga, Tatiana, Maria and Anastasia may also
have been carriers of the haemophilia gene. Maria was believed to have
haemorrhaged in 1914 during a tonsillectomy and the doctor performing the
operation had to be ordered to continue by Olga's mother. Carriers of the gene
can have similar symptoms to haemophilia including a lower blood clotting
factor, causing heavy bleeding. DNA testing on the remains of the imperial
family in 2009 proved that Alexei, his mother and one of his sisters were carriers.

It is interesting to ask 'What if?' questions about
haemophilia and its impact on the Romanovs.
Tsarina Alexandra arguably only fell in with Rasputin and
his 'spiritism' in a desperate attempt to cure and save her son (She
believed he was a holy healer, who would heal her son... Ra-Ra-Rasputin... okay
I'm done now :D)
Rasputin can also be judged to play quite a role in the
eventual fall of the Romanov dynasty. His close relationship with the imperial
family resulted in quite a bit of damage to their reputations and public image.
This may have contributed to the anger of the population and the outbreak of
the Russian Revolution.
So, is it possible that without Alexei's haemophilia, there
would have been no Russian Revolution? As the Bolsheviks and eventually the
Communist Party of the Soviet Union took control, is it also possible that
there would have been no Soviet Union, and the major events that Russia has begun
would never have happened? How different would the political landscape
potentially be?
But perhaps nothing would have been different without
haemophilia. With or without Rasputin, Tsarina Alexandra was viewed with
suspicion by the people during WW1, as she was German-born. Her reputation
certainly wasn't helped by her relationship with Rasputin, but it was never
particularly good in the first place. The people were already facing hardship
such as shortages of bread and grain and the Bolsheviks became popular
promising an end to the war, land for the lower classes and food for all. Prior
to WW1, the events of Bloody Sunday in 1905, when the Imperial Guard shot and
killed at least 100 demonstrators, had already caused anger and mistrust
towards the Tsar. It is entirely possible that the 1917 revolution and
subsequent events may have happened anyway.
It's stirring and rather poignant to think about and it
ultimately highlights how much impact a simple, random mutation can ultimately
have on you and the people around you. For me, this is part of the reason why I
think genetics is so fascinating. Something so small and seemingly
insignificant can have such wide reaching consequences.

Anastasia.
Very long article this week and thank you very much for
getting though it! Hope it was somewhat interesting for you, and I'll try to do
a shorter one next week!
