Haemophilia in European royalty

From Wikipedia, the free encyclopedia

Haemophilia figured prominently in the history of European royalty. Queen Victoria passed the mutation to her son Leopold and, through several of her daughters, to various royals across the continent, including the royal families of Spain, Germany and Russia. For this reason it was once popularly called "the royal disease".

Victoria appears to have been a de novo mutation, as her mother, Victoria, was not known to have a family history of the disease. Queen Victoria's father, Edward, was not haemophiliac, and the probability of her mother having had a lover who suffered from haemophilia is minuscule as, in the Nineteenth Century, male haemophiliacs tended to die before they could sire children.[citation needed] Descendants of Victoria's maternal half-sister, Feodora, are not known to have suffered from the disease.

The disease passed on to

Alexei's haemophilia was one of the factors contributing to the collapse of Imperial Russia during the Russian Revolution of 1917 (according to Massey, Nicholas and Alexandra, 1967). It is not known if any of Alexei's sisters were carriers, as the whole family were executed while the children were still young. One of Alexandra's daughters, Grand Duchess Maria, is thought by some to have been a symptomatic carrier because she haemorrhaged during a tonsillectomy. (Ian Vorres, The Last Grand Duchess, 1965 p. 115.)

The younger son, Prince Maurice of Teck, died in infancy, so it is not known if he was a sufferer.

Her two daughters, Infantas Beatriz and Maria Cristina of Spain, may have been carriers, but none of their descendants have had the disease as of 2006, although one of Beatriz's grandsons, Paul Weiller, son of her daughter Olimpia, died as a child, but from an unknown cause of death.

It is unknown if Victoria's third or fourth daughters, Helena or Louise were carriers. Louise died without giving birth to any children. Helena had two healthy sons, but also two younger sons who died in early infancy and two daughters who both died childless, so there may have been a possibility that either of the younger sons could have been sufferers or the daughters could have been carriers.

[edit] In Popular Culture

In the British science fiction television series, Doctor Who, the existence of the disease in Queen Victoria is said to come from a werewolf bite in Tooth and Claw.
