Haemophilia in European royalty
Haemophilia figured prominently in the history of European royalty in the 19th and 20th centuries. Queen Victoria, through two of her five daughters (Princess Alice of the United Kingdom and Princess Beatrice of the United Kingdom), passed the mutation to various royal houses across the continent, including the royal families of Spain, Germany and Russia. Victoria's son Leopold suffered from the disease. For this reason, haemophilia was once popularly called "the royal disease". The sex-linked, X chromosome disorder manifests almost entirely in males, although the gene for the disorder is inherited from the mother. However females carrying the faulty X chromosome can pass the chromosome to their descendents. Expression of the disorder is more common in males due to the fact that females have two X chromosomes while the male only has one. If a male's X chromosome is defective, there is not another to mask the disorder. In about 30% of cases, however, there is no family history of the disorder and the condition is the result of a spontaneous gene mutation. [1] Victoria appears to have been a spontaneous or de novo mutation, and is considered the source of this line of the disease. Her mother, Victoria, was not known to have a family history of the disease. Descendants of Victoria's maternal half-sister, Feodora, are not known to have suffered from the disease. Queen Victoria's father, Edward, was not a haemophiliac and the probability of her mother having had a lover who suffered from haemophilia is minuscule, primarily due to the low life expectancy of 19th century haemophiliacs. The royal families' history of haemophilia. Those who suffered from or carried haemophilia are enclosed in a box. Three of Victoria's children were unlucky. The disease passed through her daughters Alice and Beatrice and to her son Leopold.
Princess AliceAlice, Victoria's third child, passed it on to at least three of her children:
Princess Victoria of Hesse and by Rhine (later Victoria, Marchioness of Milford Haven), Alice's oldest child and maternal grandmother to Prince Philip, Duke of Edinburgh, might have inherited the mutation, though the gene remained hidden for several generations before reappearing in the descendants of her eldest granddaughter, Princess Margarita of Greece and Denmark. Princess Elizabeth of Hesse and by Rhine (later Grand Duchess Elizabeth Feodorovna of Russia), may or may not have been a carrier. She was childless when killed by the Bolsheviks in 1918. Princess Marie of Hesse and by Rhine, Alice's seventh and last child, may or may not have been a carrier. She died of diphtheria at the age of four. Prince LeopoldLeopold, Victoria's eighth child, was a haemophiliac who died from bleeding after a fall. He lived to the age of 30, long enough to pass the gene on to his only daughter:
Alice of Albany's youngest son Prince Maurice of Teck, died in infancy, so it is not known if he was a sufferer. Her daughter Lady May Abel Smith, Leopold's granddaughter, apparently was not a carrier, as the disease has not appeared in her descendants. Princess BeatricePrincess Beatrice (later Princess Henry of Battenberg), Victoria's ninth and last child, passed it on to at least two, if not three, of her children:
TodayAs of today, hemophilia is extinct in the reigning royal houses of Europe. The last royal descendant of Victoria known to suffer from the disease was Infante Gonzalo (born 1914). Many sons have been born to European royalty since and none is known to have had hemophilia. However, since the hemophilia gene remains hidden in females with only one bad gene, and female descendants of Victoria exist in several royal houses today, there remains a small chance that the disease could appear again, especially among the female-line Spanish descendants of Princess Beatrice.
Ferdinand SoltmannAt least one modern descendant of Queen Victoria has been diagnosed with haemophilia: Ferdinand Soltmann, the son of Princess Xenia of Hohenlohe-Langenberg. Xenia is a male-line descendant of Victoria, but the disease did not come from Xenia's maternal family, the Croÿs. Xenia's father, Kraft, Prince of Hohenlohe-Langenberg, had some clotting issues, which led the family to believe he may have been a mild haemophiliac.[4] As the daughter of a haemophiliac, Xenia had a 100% chance of being a carrier. Xenia is descended from Victoria twice paternally, through Victoria's children, Princess Alice of the United Kingdom and Alfred, Duke of Saxe-Coburg and Gotha. Alfred was not a haemophiliac, but Alice was a carrier, and her line of descent to Xenia, and subsequently, Ferdinand, is as follows.
