![]() ![]() However, it's wildly unlikely that modern royal children are at an increased risk for hemophilia. Part of the reason it became such an issue after Queen Victoria's reign is because her children wound up scattered throughout other European royal families, and some brought the gene with them. George's Chapel, Windsor Castle, in May 2018. Prince Harry and Meghan Markle announced their engagement in November and will marry at St. Prince Harry and Meghan Markle attend the Terrance Higgins Trust World AIDS Day charity fair at Nottingham Contemporary on December 1 in Nottingham, England. Prince Harry and Meghan Markle announced their engagement in November and. ![]() Queen Victoria's particular mutation affected clotting factor IX, which means that her affected descendants had hemophilia B. Severe hemophilia can cause spontaneous bleeding, which can cause damage wherever it happens that includes places like the joints and the brain. Because of this mutation, the proteins-called clotting factors-don't work properly. Hemophilia happens because the genes that code for proteins that help a person's body stop bleeding are mutated, according to the Centers for Disease Control and Prevention this happens to about one in every 5,000 boys born in the United States. ![]() Even if one copy of the gene is mutated, they've got a backup on the other X chromosome. That's why women almost never get hemophilia. Each person has two sex chromosomes men have one X and one Y, while women have two X chromosomes. The X chromosome is one of two sex chromosomes the other is Y. (The authors of that paper had already proven the identity of the remains they analyzed for the mutation.)īoth hemophilia A and B are caused by a mutation in a gene on an X chromosome. A 2009 paper published in Science used this familial link with the Romanovs, who were deposed and killed in 1918 after the Russian Revolution, to establish what exactly the mutation was. Thankfully, though, it's highly unlikely that any of the youngest members of the royal family might need treatment for this particular disease.Ī spontaneous mutation in Queen Victoria's DNA is probably what started it all, causing the disorder in her son, Leopold-who died from it-and other descendants, including members of the Russian royal family, the Romanovs. New gene therapy may soon be able to cure two forms of the blood disease that makes blood unable to clot properly. Hemophilia may be a rare disease, but it's certainly not an unknown one-primarily, it could be argued, because of the disease's long history with British royals. ![]()
