Clan link is clue to
saving lives!
By ALASTAIR ROBERTSON
HAVING a Scottish clan name could
provide you with more than just a romantic link to
your past, according to scientists who now believe
it could also ensure your future.
Genetic research has shown people
with the same clan name are much more closely related
than was previously thought, which should make tissue
donor matches easier to find.
That in turn could help save thousands
of leukaemia sufferers and others struck down by immune-system
disorders, according to a leading geneticist.
The findings have been revealed
at the same time as the announcement that a donor
has been found, in the face of huge odds, for Millie
Forbes, a 20-year-old Clan Forbes member from Aberdeenshire
who has acute myeloid leukaemia.
Like thousands of other sufferers
in the UK, she needs a transplant of matching bone
marrow as a last-resort treatment, after the disease
returned following successful chemotherapy.
Yesterday, her parents Jonathan
and Nicky praised the Scottish clan system in the
US for its leading role in the search for a donor.
Millie’s grandfather is Chief of Clan Forbes.
But it is not known if the donor,
whose identity is secret, is also a Forbes clan member.
Cancer experts already know that
the chances of finding matching bone marrow, or similar
tissue for medical donation, are far higher among
close family members.
Now according to research by author
Bryan Sykes, professor of human genetics at Oxford
University, it appears that even scattered clan members
are more closely related than previously thought.
This emerged during research in
the Hebrides for his book on the handing down of male
chromosomes, Adam’s Curse.
By analysing DNA samples, he found
that an unexpectedly high proportion of people called
Macdonald, plus members of related clans with different
names, were directly descended from Somerled, the
12th century warrior and founder of the clan.
Not everyone who bears a clan
name will be related to the chief, as some, such as
former slaves or criminals, may have taken the name
out of convenience.
Intermarriage and dozens of generations
will also have diluted the gene pool.
But even so, Sykes found that
20% of Macdonalds could claim Somerled as their direct
ancestor, a figure he described as "astonishingly
high".
That is likely to mean many Macdonalds
are more closely matched genetically than had been
thought.
Sykes said the same close relationship
would be true of any other clan that had distinct
territories and homeland.
And that in turns means an appeal
for donors of the same clan name - perhaps through
clan societies and associations on the internet -
could possibly narrow the field of search dramatically
and increase the chances of finding a match.
"Judging by my research on
Clan Donald, rather more Forbes members will be related
to the clan chief than is generally thought,"
Sykes said.
"So people in the clan are
more related to one another than to anyone else."
Steve Jones, professor of genetics
at University College, London, said: "I can’t
think why no one has used this idea before. It will
not guarantee a match, but it is an excellent tool
for searching for donors."
MARROW DONOR FOUND FOR
LEUKAEMIA SUFFERER
A YOUNG Scot desperately in need
of a bone marrow transplant has been found a donor
who could save her life.
Leukaemia sufferer Millie Forbes
is expected to have an operation soon following the
successful match-up. Forbes, 20, has been the subject
of intensive campaigning to recruit new bone marrow
donors by supporters across Britain.
Forbes, from Alford in Aberdeenshire,
caught the imagination of young people across the
UK when the Millie Campaign was launched in August
by her near-neighbour, comedian Billy Connolly.
It urged people to sign up to
the register of potential bone marrow donors held
by the Anthony Nolan Trust, the worldwide marrow donor
database.
Yesterday, her parents Jonathan
and Nicky praised the Scottish clan system in the
US for its leading role in the search for a donor.
Her grandfather is chief of Clan Forbes, but it is
not known if the donor, whose identity is secret,
is also a Forbes clan member.
Campaign organiser Val Rahtz said
the donor’s identity and nationality could not
be revealed because of strict confidentiality rules.
Forbes is in hospital to prepare for the surgery.
