Queen Victoria: Hemophilia & Porphyria Adam Edwards Bobby Orr Dave Grkovic Danielle Heinbaugh
Queen Victoria and the Royal Family • The traditional view is that there was a mutation in either Queen Victoria, or in a sperm of her father, Edward Augustus, Duke of Kent. • Hemophilia first appeared in Victoria's family in her eighth child, Prince Leopold, Duke of Albany. • Hemophilia spread through the Royal Houses of Europe as monarchs arranged marriages to consolidate political alliances.
Hemophilia: • Definition: A blood disease in which lack of clotting factors (factor VIII) prevents normal blood clotting • As a result, any injury in which blood flows can become lethal • Sex-linked recessive disease, females are carriers, but it primarily is shown in males • Frequency: Males 1:10000/Females 1:100,000,000 • Disease is currently treatable via infusions of “normal” blood, and direct infusions of factor VIII • This disease can occur if the immune system makes antibodies to factor VIII, the result of which is similar to an allergic reaction, and inhibition of factor VIII occurs
Porphyria: • Group of 7 disorders associated with the synthesis of heme in blood. • Heme is synthesized after 5-aminolevulinic acid undergoes 7 key enzymatic changes. • Porphyric disorders are the result of a toxin acting on one of the 7 enzymes, or a genetic defect acting on a gene coding for the biosynthesis of the enzymes. • Symptoms are the result of a backup of one of the seven enzymes as opposed to the absence of heme.
Porphyria Symptoms: • constapatedness • severe abdominal pain • anxiety, depression delerium • muscle frailty, numbness • resperatoryn weekness,excessivly rapid heart beat • skin rash, blistering • sxcessive pigmentation, excessive body hair • production of highly pigmented urine
