Yes, some types of anemia are due to inherited or genetic defects. Sickle cell anemia occurs most frequently in people of African, African-American, and Mediterranean descent. Thalassemia (or Cooley's anemia) is found in people of Mediterranean and Southeast Asian descent. These types of anemia are extremely common. Another inherited anemia is Fanconi anemia, but this is very rare.

IDA is the most common type of anemia. IDA happens when you don't have enough iron in your body. You need iron to make hemoglobin. People with this type of anemia are sometimes said to have “iron-poor blood” or “tired blood.” A person can have a low iron level because of blood loss. In women, iron and red blood cells are lost when bleeding occurs from very heavy and long periods, as well as from childbirth.

ldquo;Anemia” (uh-NEE-me-uh) occurs when you have less than the normal number of red blood cells in your blood or when the red blood cells in your blood don't have enough hemoglobin (HEE-muh-glow-bin). Hemoglobin is a protein. It gives the red color to your blood. Its main job is to carry oxygen from your lungs to all parts of your body. If you have anemia, your blood does not carry enough oxygen to all the parts of your body.

A: Some types of cancer (including melanoma and cancers of the breast, ovary, prostate, and colon) tend to occur more often in some families than in the rest of the population. It is often unclear whether a pattern of cancer in a family is primarily due to heredity (due to gene mutations), factors in the family environment or lifestyle, or just a matter of chance. Most cancer causing gene changes are the result of factors in lifestyle and environment.

Anemia takes some time to develop. In the beginning, you may not have any signs or they may be mild. But as it gets worse, you may have these symptoms: All of these signs and symptoms can occur because your heart has to work harder to pump more oxygen-rich blood through the body.

to get red blood cell counts or hemoglobin levels back to normal so that your organs and tissues can get enough oxygen The treatment your doctor prescribes for you will depend on the cause of the anemia. For example, treatment for sickle cell anemia is different than treatment for a diet low in iron or folic acid.

Eat and drink foods that help your body absorb iron, like orange juice, strawberries, broccoli, or other fruits and vegetables with vitamin C. Calcium can hurt your absorption of iron. If you have a hard time getting enough iron, talk to your doctor about the best way to also get enough calcium. Eat a balanced diet. Most people who eat a balanced diet get the iron and vitamins their bodies need from the foods they eat. Food fads and dieting can lead to anemia.

The symptoms of anemia can include headache, fatigue, weakness, difficulty in thinking. With severe anemia, other symptoms, such as shortness of breath and rapid heartbeat, may be experienced.

Genetics may play a role in PMDD. Studies have shown that identical twins are more likely to share the disorder (93%) than non-identical (fraternal) twins (44%), and daughters of mothers with PMDD are more likely to have it themselves. However, no specific genes have been identified to account for PMDD. It is best to simply say that genetics may put a woman at greater risk for developing the disorder.

There is a genetic factor in the development of allergic disease. If one parent has allergic disease, the estimated risk of a child to develop allergies is 48%; the child's estimated risk grows to 70% if both parents have a history of allergies.

Research shows that the risk for developing alcoholism does indeed run in families. The genes a person inherits partially explain this pattern, but lifestyle is also a factor. Currently, researchers are working to discover the actual genes that put people at risk for alcoholism. Your friends, the amount of stress in your life, and how readily available alcohol is also are factors that may increase your risk for alcoholism. But remember: Risk is not destiny.

Research shows that ADHD tends to run in families, so there are likely to be genetic influences. Children who have ADHD usually have at least one close relative who also has ADHD. And at least one–third of all fathers who had ADHD in their youth have children with ADHD. Even more convincing of a possible genetic link is that when one twin of an identical twin pair has the disorder, the other is likely to have it too.

In humans, there are two modes of inheritance: autosomal dominant and autosomal recessive (with at least two, and possibly three different autosomal dominant forms of PKD caused by different genes at different loci). To date, only the autosomal dominant form has been identified in cats. To quote Dr. DiBartola, Professor of Veterinary Clinical Sciences at The Ohio State University College of Veterinary Medicine, and Co-Editor of the Journal of Veterinary Internal Medicine (one of the Dr.

Genetics is a complex subject, and The Foundation Fighting Blindness has prepared another booklet, "The Inheritance of Retinal Degenerations," to explain this topic in detail. (This can be ordered by using The Foundation's Publication Order Form.) There are so many different forms of RP, which fall within one of three standard inheritance patterns. Each type of inheritance will create a different pattern of affected and unaffected family members.

Most cases of PWS are attributed to a spontaneous genetic error that occurs at or near the time of conception for unknown reasons. In a very small percentage of cases (2 percent or less), a genetic mutation that does not affect the parent is passed on to the child, and in these families more than one child may be affected. A PWS-like disorder can also be acquired after birth if the hypothalamic portion of the brain is damaged through injury or surgery.

Most cases of epilepsy are not inherited, although some types have a genetic basis. Most of these types are easily controlled with medication. Epilepsy syndromes with a genetic basis: Primary Generalized Epilepsies, Benign Rolandic Epilepsy, Nocturnal Frontal Lobe Epilepsy, Familial Temporal Lobe Epilepsy, Benign Familial Neonatal Seizures and Benign Familial Infantile Spasms.
