It wasn't, however, hemophilia B that killed the Russian prince and his sister-likely Anastasia-rumored to have escaped the Bolshevik revolutionaries who assassinated the other Romanovs in 1918. Hemophilia A is a clotting factor VIII deficiency (factor VIII assists with blood coagulation), while hemophilia B is a clotting factor IX deficiency (factor IX is an enzyme in the coagulation system). They found a mutation that would have led to an "abnormal splicing site" on the factor IX gene, a tale-tell sign of hemophilia B, which is far more rare than hemophilia A and now appears to be extinct in the European royal lines. Using sequencing and amplification techniques, the investigators were able to obtain gene sequences from the 91-year-old material. The authors of the new study, led by Evgeny Rogaev of the University of Massachusetts Medical School and Lomonosov Moscow State University in Russia, sampled bones found in the Ural Mountains in 2007 now known to belong to the son of Russian Empress Alexandra (Victoria's granddaughter), Crown Prince Alexei, and one of his sisters. Those who manifest the disease often have excessive bleeding, as the blood does not properly coagulate, which can lead to pain and even death. It is also recessive and is more commonly exhibited in males, causing it to go undetected in many carriers, who may pass it on to future generations. Hemophilia is caused by a mutation-likely spontaneous in Victoria's case-on the X chromosome and can be passed along the maternal line of families.

Research published online today in Science sheds some light on the mystery thanks to advances in genetic research and the 2007 discovery of some long-lost Russian remains. But it has remained unknown precisely what variety of the disease afflicted the family and how many deceased relatives may have had the inherited disease. Queen Victoria and many of her descendants carried what was once called "Royal disease"-now known as hemophilia, a blood clotting disorder. But since Phillip did not inherit hemophilia from his mother (not a carrier) or grandmother (also not a carrier but with a flip of the genetic coin might have been), and since Queen Elizabeth had no hemophilia in her direct line, neither Charles nor his sons, William and Harry, have hemophilia.This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Now, Queen Elizabeth and Prince Phillip are related as third cousins. She is a direct descendant of King Edward VII, a son of Queen Victoria who did not have hemophilia. Queen Elizabeth? Not so much drama with hemophilia. So, Prince Phillip has a long and illustrious side to his family tree regarding hemophilia! It’s been proposed that Nicholas II was so distracted by his son’s suffering due to hemophilia, that eventually he lost his grip on the monarchy at a time when the Bolshevik Revolution was poised to strike. Alix married the Tsar of Russia, Nicholas II, and gave birth to Alexis, who had hemophilia. There were 7 Hesse children, and like their grandmum, one had hemophilia (Frederick) and two were carriers (Victoria, Phillip’s grandmother, and Alix). Alice introduced hemophilia into the House of Hesse and this German lineage. These are very good odds!Īlice married Louis IV, the Grand Duke of Hesse. In fact Queen Victoria had nine children, of whom two were carriers (Alice and Beatrice) and one had hemophilia (Leopold). Phillip was descended from the third child of Queen Victoria, also called Alice, who like her mother, was a carrier for factor IX deficiency, or hemophilia B. His mother, Princess Alice, was a great-granddaughter of Queen Victoria. Prince Phillip was born a prince (unlike Diana, Camilla, Kate and Megan, who married into the family).
