Haemophilia In European Royalty

Haemophilia figured prominently in the history of European royalty in the 19th and 20th centuries. Queen Victoria and her husband, Prince Albert of the United Kingdom, through two of their five daughters – Princess Alice and Princess Beatrice – passed the mutation to various royal houses across the continent, including the royal families of Spain, Germany and Russia. Victoria's youngest son, Prince Leopold, Duke of Albany, also had the disease, though none of her three elder sons did. Tests on the remains of the Romanov imperial family show that the specific form of haemophilia passed down by Queen Victoria was probably the relatively rare haemophilia B."Case Closed: Famous Royals Suffered from Hemophilia".
Michael Price, ScienceNOW, October 9, 2009. The presence of haemophilia B within the European royal families was well known, with the condition once popularly termed the 'royal disease.'

Genetic inheritance of haemophilia

The sex-linked X-chromosome bleeding disorder manifests almost exclusively in males, even though the genetic mutation causing the disorder is located on the X-chromosome and can be inherited from the mother by male children or from either mother or father by female children. This is because the trait is recessive, meaning that only one correctly functioning copy of the blood-clotting factor gene is necessary for normal clotting. Females have two X-chromosomes, and hence redundant copies of the blood-clotting factor gene located on them. A female who inherits a mutated copy on one X-chromosome has also inherited a second X-chromosome from the other parent that is likely to carry a non-mutated copy of the gene, capable of directing appropriate clotting. Such a female, with normal clotting but possessing a single mutated copy of the gene, is called a carrier. Males possess only a single X-chromosome, inherited from their mother, having received a Y-chromosome from their fathers instead of a second X. If their sole X-chromosome contains the haemophilia mutation they possess no second copy to provide for normal function, as in carrier females. Each child of a carrier will have a 50 percent chance of inheriting their mother's mutation, of being a haemophiliac (sons) or carrier (daughters). The daughter of a male haemophiliac will always inherit his mutation, while a son cannot ever inherit it. A female will be affected with haemophilia proper only in the rare circumstance that she inherits mutated X-chromosomes from both a haemophiliac father and a carrier or a haemophiliac mother. No case of such double inheritance is known among Queen Victoria's descendants, although there has been at least one symptomatic carrier.

Although an individual's haemophilia can usually be traced in the ancestry, in about 30 percent of cases, there is no family history of the disorder, and the condition is speculated to be the result of spontaneous mutation in an ancestor. Victoria's appears to have been a spontaneous or ''de novo'' mutation, most likely inherited from one of her parents, and she is usually considered the source of the disease in modern cases of haemophilia among her descendants. Queen Victoria's mother, Victoria, Duchess of Kent, was not known to have a family history of the disease, although it is possible that she was a carrier, but among her three children only Victoria received the mutated copy. Queen Victoria's father, Prince Edward, Duke of Kent, was not a haemophiliac, but the mutation may have arisen as a germ-line mutation within him. The rate of spontaneous mutation is known to increase with paternal age (and is higher in fathers than in mothers at all ages); Victoria's father was 51 at her birth. The probability of Victoria's mother having had a lover with haemophilia is minuscule, given the low life expectancy of early 19th-century haemophiliacs, as well as the otherwise low possibility of illegitimacy in this instance.

Queen Victoria's eldest daughter, Victoria, Princess Royal, apparently escaped the haemophilia gene, as it did not appear in any of her matrilineal descendants. Victoria's fifth child, Princess Helena, may or may not have been a carrier; two healthy sons survived to adulthood, but one son died in infancy, another was stillborn, and her two daughters did not have issue. Victoria's sixth child, Princess Louise, died without issue. Queen Victoria's sons Edward VII, Alfred, Duke of Saxe-Coburg and Gotha, and Prince Arthur, Duke of Connaught and Strathearn were not haemophiliacs; however, her daughters Alice and Beatrice were confirmed carriers of the gene, and Victoria's son Leopold had haemophilia, making his daughter Princess Alice, Countess of Athlone a carrier as well.

Princess Alice

Alice (1843–1878), Victoria's third child, and wife of the future Grand Duke Louis IV of Hesse and by Rhine (1837–1892), passed it on to at least three of her children: Irene, Friedrich, and Alix.
* Princess Victoria of Hesse and by Rhine (1863–1950), later Marchioness of Milford Haven, wife of Prince Louis of Battenberg (1854–1921) and maternal grandmother to Prince Philip, Duke of Edinburgh, apparently was not a carrier.
* Princess Elizabeth of Hesse and by Rhine (1864–1918), later Grand Duchess Elizabeth Feodorovna of Russia through her marriage to Grand Duke Sergei Alexandrovich (1857–1905), may or may not have been a carrier. Following her husband's assassination, she became a nun and was childless when killed by the Bolsheviks in 1918.
* Princess Irene of Hesse and by Rhine (1866–1953), later Princess Heinrich of Prussia, through her marriage to Prince Heinrich of Prussia (1862–1929), passed it on to two of her three sons:
** Prince Waldemar of Prussia (1889–1945). Survived to age 56; had no issue.
** Prince Henry of Prussia (1900–1904). Died at age 4.
* Prince Friedrich of Hesse and by Rhine (1870–1873). Died before his third birthday of bleeding on the brain resulting from a fall from a third-story window (which would almost certainly have not been fatal if he had not had haemophilia).
* Princess Alix of Hesse and by Rhine (1872–1918), later Empress Alexandra Feodorovna of Russia through her marriage to Tsar Nicholas II (1868–1918). Alix had a marriage proposal from her first cousin, Prince Albert Victor (1864–1892), eldest son of the then Prince of Wales (later King Edward VII); had she accepted, haemophilia could have returned to the direct line of succession in the United Kingdom.
** Grand Duchess Maria Nikolaevna (1899–1918), Nicholas and Alexandra's third daughter, was thought by some to have been a symptomatic carrier because she haemorrhaged during a tonsillectomy. DNA testing of the Romanov family remains in 2009 showed that one of the four daughters, thought to be Maria by American researchers and Anastasia by Russian researchers, was a carrier.
** Tsarevich Alexei (1904–1918) was murdered with his family by the Bolsheviks at the age of 13. Alexei's haemophilia was one of the factors contributing to the collapse of Imperial Russia during the Russian Revolution of 1917.Massey, ''Nicholas and Alexandra,'' 1967
* Princess Marie of Hesse and by Rhine (1874–1878), Alice's seventh and last child, may or may not have been a carrier. She died of diphtheria at the age of four.

Prince Leopold

Leopold (1853–1884), Victoria's eighth child, was the first member of the family to manifest haemophilia; he died at age 30 from bleeding after a minor fall, only two years after marrying Princess Helen of Waldeck and Pyrmont (1861–1922).

He passed the gene on to his only daughter:
* Princess Alice of Albany (1883–1981), later Countess of Athlone, who in turn passed it on to her elder son:
** Prince Rupert of Teck (1907–1928), later Rupert Cambridge, Viscount Trematon, who died at age 20, bleeding to death after a car accident.

Alice's younger son Prince Maurice of Teck died in infancy, so it is not known if he was a carrier of the gene. Her daughter Lady May Abel Smith (1906–1994), Leopold's granddaughter, has living descendants none of whom has been known to have or to transmit haemophilia.

Leopold's posthumous son, Charles Edward (1884–1954), was unaffected, as a father cannot pass the gene to a son.

Princess Beatrice

Beatrice (1857–1944), Victoria's ninth and last child, and wife of Prince Henry of Battenberg (1858–1896) passed it on to at least two, if not three, of her four children:
* Princess Victoria Eugenie of Battenberg (1887–1969), later Queen Victoria Eugenia of Spain through her marriage to King Alfonso XIII (1886–1940), who passed it on to:
** Infante Alfonso, Prince of Asturias (1907–1938). Died at age 31, bleeding to death after a car accident.
** Infante Gonzalo (1914–1934). Died at age 19, bleeding to death after a car accident.
** Victoria Eugenie's two daughters, Infantas Beatriz (1909–2002) and Maria Cristina of Spain (1911–1996), both have living descendants none of whom has been known to have or to transmit haemophilia.
* Prince Leopold of Battenberg (1889–1922); later Lord Leopold Mountbatten. Died at age 32 during a hip operation.
* Prince Maurice of Battenberg (1891–1914). Killed in action in World War I at the age of 23. Maurice's haemophilia is disputed by various sources. It seems unlikely that a known haemophiliac would be allowed to serve in combat.

Today

No living member of the present or past reigning dynasties of Europe is known to have symptoms of haemophilia or is believed to carry the gene for it. The last descendant of Victoria known to have the disease was Infante Gonzalo, born in 1914, although hundreds of descendants of Queen Victoria's (including males descended only through females) have been born since 1914. However, because the haemophilia gene usually remains hidden in females who only inherit the gene from one parent, and female descendants of Victoria have left many descendants in royal and noble families, there remains a small chance that the disease could appear again.

Chronological order

Queen Victoria died in 1901 and outlived her youngest son and a grandson, both of whom had the disease. The gene can be passed down the female line without a haemophiliac son being born, but as the family line continues and no haemophiliac sons are born, it becomes less likely that a certain ancestor had the gene and passed it on through the female line.

Type of haemophilia discovered

Because the last known descendant of Queen Victoria with haemophilia died a few months before the end of WWII, in 1945, the exact type of haemophilia found in this family remained unknown until 2009. Using genetic analysis of the remains of the assassinated Romanov dynasty, specifically those of Tsarevich Alexei, Rogaev et al. were able to determine that it was haemophilia B. Specifically, they found a single-nucleotide change in the gene for clotting Factor IX that causes incorrect RNA splicing and produces a truncated, nonfunctional protein.
