When parents are blood relatives, there is a higher risk of disease and birth defects, stillbirths, infant mortality and a shorter life expectancy. To have a child with severe diseases and disorders may cause heavy strain for the family in question.
What happens when blood relatives have a baby?
Individuals who are blood relatives are more likely to be silent carriers for the same recessive condition(s), hence the risk of autosomal recessive genetic disorders is higher in children born from consanguineous unions.
What happens when relatives have kids together?
When closely related people have kids, they are more likely to share a lot of the same gene versions. This means they are more likely to pass down the same gene versions to their kids too.
How can family history affect your health?
A family health history can identify people with a higher-than-usual chance of having common disorders, such as heart disease, high blood pressure, stroke, certain cancers, and type 2 diabetes. These complex disorders are influenced by a combination of genetic factors, environmental conditions, and lifestyle choices.
The offspring of consanguineous relations have an average increased risk of 2-4\% of congenital/genetic disorders and early mortality.
What are the common illnesses in your family?
10 diseases and medical conditions that can ‘run in the family’
- CANCER. This is always top of the list in terms of the anxiety it causes people, but interestingly only a few cancers actually pose a risk to relatives.
- CARDIOVASCULAR DISEASE.
- OSTEOPOROSIS.
- EYE HEALTH.
- ARTHRITIS.
- DEMENTIA.
- BLOOD CLOTS.
- DIABETES.
Why is family health important?
According to Dr. James Martin from the Academy of Family Physicians, families establish patterns of preventive care, exercise, hygiene, and responsibility, and they set the foundation for self-worth, resilience, and the ability to form healthy and caring relationships.
What would happen if a brother and sister had a kid?
The risk for passing down a genetic disease is much higher for siblings than first cousins. To be more specific, two siblings who have kids together have a higher chance of passing on a recessive disease to their kids.
What are the risks of having children with a second cousin?
Further, if you include second cousins in the mix, according to the Clinical Genetics Handbook, the increased risks with regards to having children are nearly non-existent in this case compared with non-cousin marriage.
Do first cousins have more birth defects?
A recent report on births in a British-Pakistani community (where first cousin marriage is very common) demonstrated that first cousin children there were twice as likely to be born with “ potentially life threatening birth defects ” as compared with the children of unrelated parents.
How do first degree relatives cause genetic defects?
The reason having offspring with a first degree relative (siblings, parents, first cousins, aunts, uncles, etc) can cause defects is because it amplifies any genetic defects as well as making the chance of a child receiving some sort of defect caused by a recessive gene (meaning you need two of them for the defective to occur) much more likely.
Why is it bad to have the same genes as parents?
And because both parents have the same recessive traits, the chance of bad things happening gets bigger. In the general population, you might have a 1\% chance of some birth defect. Because even people not related to you will have the same recessive genes.
