Hemophilia is a medical condition in which the ability for blood clotting is severely reduced. This causes patients to bleed severely from any slight injury. Hemophilia can affect anyone, no matter race, color and ethnic origin. There are two types of Hemophilia, A and B. Hemophilia A affects 1 of every 5000 males in the U.S and approximately 400 babies are born with Hemophilia every year. Today about 400,000 people are living with hemophilia worldwide, and about 20,000 live in the U.S alone. Hemophilia is caused due to a gene mutation, that provides instructions for blood clotting protein needed to form blood clot.Mutations in the FVIII gene causes hemophilia A, while mutations in the FIX gene causes hemophilia B.This change in gene can prevent the clotting protein from working properly. When patients are diagnosed with hemophilia there prognosis can be mild, moderate, or severe, depending on how much clotting factor is in an affected person's blood. However, about 70% of patients have the severe form of this disorder. In order to treat hemophilia it requires …show more content…
In a normal male, his genotype would be XHY, while in a normal female it would be XHXH. On the flip side, an affected male genotype would be XhY, while a carrier female genotype is XhXH. When a phenotype is being affected, the effect occurs on the X chromosomes making hemophilia less likely and very mild on women. In females, the extra X chromosomes are inactivated so the effects of it are not seen. Taking a closer look , the gene type in the females with the extra X chromosome will be XXX, and in a male with the extra X chromosome it will be XXY or XXXY instead of just XY. However, in males the extra X chromosome gets activated and creates problems That is how the phenotypic effects of hemophilia can be seen more in males. A female with with one affected X chromosomes is a carrier of
