Is factor 7 gene mutation (heterozygote) thrombophila?

Is factor 7 gene mutation (heterozygote) thrombophila?

No: Factor 7 mutation is very rare and causes increased risk of bleeding (not being able to clot). Factor 5 deficiency is the most common form of thrombophilia (increased risk of abnormal clotting). ...Read more

Genetic (Definition)

From a medical standpoint, "genetic" refers to the potential heritability of various medical conditions. While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more

Does alpha thalassemia trait have gene therapy available?

Does alpha thalassemia trait have gene therapy available?

No: Alpha thalassemia trait only causes mild anemia, and the person usually has no symptoms. Gene therapy is not available and would not be needed. ...Read more

Does mthfr heterozygous c677t mutation affect pregnancy?

Likely not much: The existing evidence does not support any strong connection between heterozygotes for either the c or a mutations of mthfr and poor pregnancy outcomes. Homozygotes may well be at greater risk. Depending on clinical history, different levels or surveillance and possible intervention can be considered. ...Read more

Is pyruvate dehydrogenase deficiency heritable?

Is pyruvate dehydrogenase deficiency heritable?

Yes.: In the most common situation it is inherited in an x-linked pattern, affecting hemizygous males (with one x chromosome) and heterozygous females (two x chromosomes, one with mutation). Less commonly it is inherited in an autosomal recessive pattern, in which a mutation must be provided by both the mother and the father of the affected person. ...Read more

Does heterozygous for MTHFR gene mutation affect pregnancy?, and what about taking synthetic folic acid supplement?

Does heterozygous for MTHFR gene mutation affect pregnancy?, and what about taking synthetic folic acid supplement?

Controversial...: Some studies have shown an association between the MTHFR gene mutation and recurrent miscarriages but this is controversial. Aside from this possibility, it doesn't cause problems with pregnancy. If you have this mutation, its a good idea to take folic acid, vitamin B-12 and Vitamen B-6. Aspirin is also sometimes recommended for women for who have had recurrent miscarriages. Best wishes! ...Read more

Is the beta-thalassemia gene recessive or dominant?

Is the beta-thalassemia gene recessive or dominant?

Neither: People normally have 2 beta globulin genes. A mutation in one or both genes leads to 3 levels of beta thalassemia. The genetics of the disorder is not all-or-none nor dominant-recessive. Instead, more or worse mutations causes worse disease. One mutation = beta thal trait (mild symptoms), 2 mutations = beta thal intermedia (transfusions sometimes) or beta thal major (lifelong transfusions needed). ...Read more

What is a hereditary hemochromatosis DNA mutation?

Gene Mutation: This is a mutation in one of the genes that help to process iron absorption. The mutation, if present in 2 copies, can cause too much iron to be absorbed. The excess iron then deposits in other organs and can cause disease - cirrhosis, diabetes, impotence. Having only one mutation may not lead to disease. You should discuss this with your doctor to see if you are at risk of developing disease. ...Read more

Sickle trait is a recessive gene?

basically yes: The mutation that causes sickle cell disease is a recessive mutation in that you need two copies of the changed gene to have the disease (or one copy plus another mutation on the other gene like beta thalassemia, hemoglobin c, hemoglobin e, etc). If you only have one copy, you have sickle cell trait. ...Read more

What is hemagglutinin (ha) gene and neuraminidase (na) gene?

What is hemagglutinin (ha) gene and neuraminidase (na) gene?

Flu virus genes: The hemaglutinin and neuraminidase genes are in influenza viruses. They code for proteins that are found on the surface of the flu virus. The viruses are named according to which type of hemaglutinin and neuraminidase proteins are on their surfaces (for example: h1n1 or h7n9). ...Read more

Can alpha thalassemia be dominant?

Can alpha thalassemia be dominant?

Not quite: People normally have 4 Alpha globulin genes. A mutation in 1, 2, 3, or all 4 genes leads to the 4 levels of Alpha thalassemia. The genetics of the disorder is not all-or-none, not dominant-recessive. Instead, the more mutations, the worse the disease. One mutation = silent carrier (no symptoms), 2 muta. = Alpha trait (mild symptoms), 3 muta. = HGB h (moderate symptoms), 4 muta. = bart's (deaths). ...Read more

Etiology of DNA mutations?

Etiology of DNA mutations?

Replication error: Most changes in dna come from errors in the duplication of the dna. But changes can occur in the structure from radiation and some chemicals especially those used in chemotherapy. Most mutations are harmless, some are tracked down by your normal reparative mechanism but a few can cause trouble including cancer. ...Read more

Beta thalesemic carrier state...Meaning?

Genes: To have beta thalessemia, you have to have 2 copies of a particular gene. If you only have 1 copy, you don't have the disease, but you do carry the trait, and can pass it to your children. If your partner also is a carrier of the gene, then there is a 1 in 4 chance that your child will have beta thalessimia. ...Read more
