TODAY, March 21st, 2009, World Down Syndrome Day is celebrated by families and friends across the globe to mark
the 50th anniversary of the publication of Professor Jerome Lejeune’s
discovery of the extra copy of chromosome 21 which causes Down
Now known as trisomy-21 because of the third copy of
the 21st chromosome, Down Syndrome was first described by the English
doctor, John Langdon Down, in 1866 but until Professor Lejeune’s
publication in 1959, the ultimate cause of Down Syndrome was unknown.
I’m thankful for this unique and precious chromosome 21 that makes our little Seth, and countless others, the precious, perfect gifts they are! The Fun House is celebrating life today!!!!
