Genes and Society: How a gene mutation changed the course of world history Eric Yap Defence Medical Research Institute Singapore Eye Research Institute COFM Dept, National University of Singapore [email protected] Portrait of Queen Victoria by Heinrich von Angeli (1840-1925) © Royal Collection http://www.royal.gov.uk /history/victoria.htm Queen Victoria and Prince Albert with their nine children (1857). Left to right: Prince Alfred, Prince Albert, Princess Helena, Prince Arthur, Princess Alice, Queen Victoria with Beatrice, Princess Victoria, Princess Louise, Prince Leopold and Prince Edward. The Royal Archives (copyright Her Majesty the Queen.) Prince Leopold with Sir William Jenner at Balmoral in 1877.

(Radio Times Hulton Picture Library.) “The Khlysty sect (which influenced Rasputin) believed that one should sin as much as possible so that repentance would be the greater and one’s salvation the more resounding. For all that, he was a drunken, coarse, treacherous and offensive rapist.” RASPUTIN Poet. Magician. Healer. Prophet. Holy Monk. http://www.sptimes.ru/archive/ ifestyl/107/rasputin.jpg An early practitioner of complementary medicine? “the poor child lay in pain, dark patches under his eyes and his little body all distorted and the leg terribly swollen. The doctors were jus useless … more frightened than any of us … kist whispering among themselves. Alicky then sent a message to Rasputin … he reached the palace around midnight. The following morning, I just could not believe my eyes. The little boy was not just alive but well. He was sitting up in bed, the fear gone, his eyes clear and bright, not a sign of swelling in the leg. Later I learned from Alicky that Rasputin had not even touched the child, but merely stood at the foot of the bed and prayed.” Olga (Alexis’ older sister) Portrait of Grigory Rasputin Yelena Klokacheva 1871-after 1915 1914 http://www.hermitagemuseum.org/html_En/03/hm 3_6_7e.html Assasinated Dec 1916 By two members of Romanov family - poisoned by cyanide - shot twice in the chest - shot twice in the head - drowned in icy canal Archduke Franz Ferdinand (heir to throne of Austro-Hungarian Empire) and wife Sophie in Sarajevo, shortly before their assasination on 28 June 1914 by Gavrilo Princip, a member of the Serbian Black Hand gang. This event was to lead to the First World War. 4 million died in first year of war Government and military incompetence Food and fuel shortages Bolshevik Revolution 1917 Nicholas II abdicated Michael (brother) abdicated End of 300 yr Romanov dynasty British asylum refused by King George V 16 July 1918 Ekaterinburg All 7 members of royal family, doctor and 3 servants executed. http://129.128.91.75/de/genetics/70gen-hemophil.html from VP Johnson, C Christianson HEMA gene is 1000kb from the Xq telomere (Xqter) 186kb, 26 exons Chromosomal localisation and structure of the factor VIII gene http://europium.csc.mrc.ac.uk/usr/WWW/WebPages/database.dir/review.dir/Review txt.html THE COAGULATION CASCADE Amino acid homologies of factor VIII domains. The A and C domains have significant homology with coagulation factor V. All three A domains have homology with ceruloplasmin and ferroxidase, while the C domains also have homology with discoidin lectins from Dictyostelium discoides and mouse milk fat globule membrane protein.

FIXa: two loops, in A2 (S558-Q565) and A3 (E1811-K1818), are shown in pink on the surface of a CPK FVIII image: view perpendicular to the three-fold axis with 'top' and 'bottom' of the molecule marked.
