There are two genetic diseases that were (and are) in Queen Victoria's family. The first one was porphryia which is an autoimmune disease, which was passed on through the Hanoverian line historians believe thanks to Margaret Tudor (the daughter of Henry VIII) The other genetic disease that was in Queen Victoria's family was hemophilia which prevents blood from clotting. It is known that Queen Victoria was a carrier of hemophilia and passed it on to three of her children and at least 6 of her grandchildren and many grandchildren, but it is impossible that she could have carried the gene for both Hemophilia and porphryia (the chance of it happening is the same as the population of the world when she was born.)
