What are the manifestations of hemophilia describe each manifestation?
What are the manifestations of hemophilia describe each manifestation?
Signs and Symptoms Common signs of hemophilia include: Bleeding into the joints. This can cause swelling and pain or tightness in the joints; it often affects the knees, elbows, and ankles. Bleeding into the skin (which is bruising) or muscle and soft tissue causing a build-up of blood in the area (called a hematoma).
What does it mean to be heterozygous for hemophilia?
A female with a hemophilia allele on one X chromosome usually has a normal allele on her other X chromosome that can produce normal clotting factor, so she has some protection against having hemophilia. A female with one hemophilia allele and one normal allele is called heterozygous or a carrier.
Do carriers of hemophilia have symptoms?
Hemophilia Carriers A female who inherits one affected X chromosome becomes a “carrier” of hemophilia. She can pass the affected gene on to her children. In addition, a female who is a carrier sometimes can have symptoms of hemophilia. In fact, some doctors describe these women as having mild hemophilia.
Is hemophilia heterozygous or homozygous?
The disease is inherited as an X-linked recessive trait and thus occurs in males and very rarely in homozygous females. Heterozygous females for the disease are known as carriers.
Can a male be heterozygous for hemophilia?
One female is heterozygous for the hemophilia trait and is considered a carrier. One male receives a damaged X-chromosome and inherits the condition known as hemophilia….A female carrier of hemophilia x A male.

How do you test for hemophilia carrier?
There are two blood tests that can be done to find out if you are a hemophilia carrier.
- A test for factor levels. People who have a low-normal Factor VIII or Factor IX level may be hemophilia carriers.
- A genetic test. This test can confirm if either you or your child is a hemophilia carrier.
What is a heterozygous female?
Heterozygous just means that a person has two different versions of the gene (one inherited from one parent, and the other from the other parent).
Which hemophilia is worse A or B?
Haemophilia B is clinically less severe than haemophilia A: further evidence – PMC.
Which gender child might be born with hemophilia?
This normal X chromosome protects a female from the severe form of hemophilia, even though some females may have more bleeding than a normal person. A female can be born with severe hemophilia if both her X chromosomes carry the hemophilia gene.
