Males are affected more often than females
because the gene is located on the X chromosome
. Hemophilia. Hemophilia is a disorder in which the blood cannot clot correctly because of a lack of a clotting factor called factor VIII. This results in heavy bleeding that will not stop, even from a small cut.
Why is haemophilia common in males?
Since males have only a single copy of any gene located on the X chromosome, they cannot offset damage to that gene with an additional copy as can females. Consequently,
X-linked disorders such
as Hemophilia A are far more common in males.
Is Hemophilia more common in males?
Hemophilia occurs more commonly in males than in females
. The two most common types of hemophilia are hemophilia A (also known as classic hemophilia) and hemophilia B (also known as Christmas disease). People who have hemophilia A have low levels of a blood clotting factor called factor eight (FVIII).
Can hemophilia be cured?
There is currently no cure for hemophilia
. Effective treatments do exist, but they are expensive and involve lifelong injections several times per week to prevent bleeding.
What race is most affected by hemophilia?
The average age of persons with hemophilia in the United States is 23.5 years. Compared to the distribution of race and ethnicity in the U.S. population,
white race is more common
, Hispanic ethnicity is equally common, while black race and Asian ancestry are less common among persons with hemophilia.
Can males pass on hemophilia?
Thus,
males can have a disease like hemophilia if they inherit an affected X chromosome that has a mutation in either the factor VIII or factor IX gene
. Females can also have hemophilia, but this is much rarer.
Is hemophilia caused by inbreeding?
Though rare in the general population, the frequency of the mutated allele and the incidence of the disorder was greater among the royal families of Europe due to the
high levels of royal inbreeding
. A case in which the presence of hemophilia B had a particularly significant effect was that of the Romanovs of Russia.
Can a female get hemophilia?
Hemophilia can affect women
, too
When a female has hemophilia, both X chromosomes are affected or one is affected and the other is missing or non-functioning. In these females, bleeding symptoms can be similar to males with hemophilia. When a female has one affected X chromosome, she is a “carrier” of hemophilia.
Is Hemophilia A serious disorder?
People with hemophilia can experience spontaneous or internal bleeding and often have painful, swollen joints due to bleeding into the joints. This
rare but serious condition can have life-threatening complications
. The three forms of hemophilia are hemophilia A, B, and C.
Can you have a baby if you have hemophilia?
If the mother is a hemophilia carrier,
there is a chance that the baby will be born with hemophilia
. In families with a known history of hemophilia, or in those with a prenatal genetic diagnosis of hemophilia, one can plan special testing for hemophilia before the baby’s delivery.
At what age is hemophilia diagnosed?
In the United States, most people with hemophilia are diagnosed at a very young age. Based on CDC data, the median age at diagnosis is
36 months for people with mild hemophilia
, 8 months for those with moderate hemophilia, and 1 month for those with severe hemophilia.
What famous person has hemophilia?

Today, no living members of reigning dynasties are known to have symptoms of hemophilia
.
How long is the average lifespan of a person with hemophilia?
During this period, it exceeded mortality in the general population by a factor of 2.69 (95% confidence interval [CI]: 2.37-3.05), and median life expectancy in severe hemophilia was
63 years
.
Can a father pass hemophilia to his son?
A father who has hemophilia passes his only X chromosome down to all of his daughters, so they will always get his hemophilia allele and be heterozygous (carriers). A father passes down his Y chromosome to his sons; thus, he
cannot pass down a hemophilia allele
to them.
What foods to avoid if you have hemophilia?
