Good
morning one and all :)
So I have
reached blog post number 100! I wanted to mark this milestone by dedicating it
to our wonderful Georgie. So I am going to use this post to provide information
on the gene mutation that led to him becoming ill and passing away at such a
young age. Everybody knows that Georgie is the main inspiration behind this
blog and all the work I do in the fight against cancer and I miss him everyday.
Thank you very much to everyone who reads my blog, I can’t believe I’ve managed
to get to 100 posts! Here’s to the next 100 :)
The TP53
Gene:
The TP53
gene acts as a tumour suppressor. It creates the p53 protein which kills
cancerous cells. When the TP53 gene fails, the body loses one of its key ways
of stopping damaged cells developing into cancer. Some people with cancer find
their TP53 gene is damaged within the tumours but is functioning normally
throughout the rest of their body. However, some people are born with a damaged
TP53 gene. These is usually an inherited problem and it passed down from parent
to child. These people have a very very very high risk of developing cancer.
Li Fraumeni
Syndrome:
LFS is one
of the most serious kinds of inherited TP53 disorders. It is a rare disorder
that greatly increases the sufferers risk of developing several kinds of cancer
especially children and young adults. The most common cancers associated with
LFS are: breast cancer, osteosarcoma (a type of bone cancer) and soft tissue
sarcomas.
Diagnosing
Li Fraumeni Syndome:
LFS is rare
so not much is known about it. Genetic testing and genetic counselling are used
to confirm whether or not someone is suffering from LFS. If it is confirmed
then this person will need to be regularly screened to check for cancer. The
sad fact is, people with LFS are very likely to develop cancer so it is hugely
important for them to be screened as cancer is easier to treat the earlier it
is diagnosed.
Please look
into genetic testing if you meet the following criteria:
An
individual with:
·
Adrenocortical
cancer at any age
·
Choroid plexus
cancer at any age
·
Rhabdomyosarcoma
below 5 years
·
Breast cancer
below 30 years old (if eligible for BRCA1/2 testing, this should be performed
first)
·
Two or more
primary cancers of the following: sarcoma, breast, brain, adrenocortical or any
childhood cancer; at least one below 46 years old
Two
relatives affected with:
·
Sarcoma, breast,
brain, adrenocortical or any childhood cancer; one relative below 36 yrs and
one relative below 46 years old
Three
relatives affected with:
·
Sarcoma below 45
yearrs old and
·
any cancer below
45 years old and
·
any cancer below
45 years old or sarcoma at any age
Georgie and
Li Fraumeni Syndrome:
Georgie’s
mum died when Georgie was one years old. She was 29 years old and had ovarian
cancer. Georgie was then diagnosed with cancer a few months later on his second
birthday. At the time it was written off as a horrific coincidence by doctors.
It wasn’t until Georgie was diagnosed with cancer for the third time at the age
of fifteen that we discovered he had Li Fraumeni Syndrome which has probably
been inherited from his mother.
It took a
very long time for Georgie to be diagnosed with the osteosarcoma that
eventually killed him. At first he was told it was a dental problem. Had we
have known he had LFS; he could have been diagnosed much quicker as alarm bells
would have been ringing. We will never know if this could have saved his life.
We live with the “what if?”
LFS and
other TP53 disorders are rare and not much is known about them. There is little
awareness about them amongst the general public and even the medical
profession. There aren’t any dedicated support groups or charities, no information
resources and no registry of the sufferers. There isn’t a community for the
sufferers which can make it very isolating, lonely and terrifying for the
sufferers and their families.
As I have
mentioned before, my uncle has set up the George Pantziarka TP53 Trust to
honour Georgie’s memory by providing support to families and individuals, to
provide information on TP53 disorders including LFS and to get research funded
to look into the condition. Hopefully the trust will be registered as a charity
one day soon and will continue to grow.
At the
moment the trust has a forum on the website which is used to bring together
people affected by the condition. Please do take a look and feel free to ask
any questions – my uncle is always happy to answer!
