Is hemophilia a gene mutation?

Is hemophilia a gene mutation?

Yes: Both hemophilia a and b are due to mutations in genes on the x chromosome. ...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

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

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

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

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

Is sickle cell dominant or recessive in its inheritance?

Is sickle cell dominant or recessive in its inheritance?

Recessive: Sickle cell is autosomal recessive which means both parents must have a copy of the defective allele (one or both can be carriers but exhibit no symptoms). ...Read more

Are gene mutations common? What about deletions?

Are gene mutations common? What about deletions?

Gene mutations: Truthfully, the human genome project has revealed that mutations are common. Deletions exist. The impact is not fully understood. But is real. ...Read more

Gene expression profiling predicts clinical outcome of breast cancer?

Gene expression profiling predicts clinical outcome of breast cancer?

We're Getting There: In the past, we used anatomic staging alone (tumor size, lymph node involvement) to guide rx. Gene profiling allows us a completely separate measure of prognosis, and, more importantly, can predict who may or may not benefit from different chemotherapy agents. In the future, we will hopefully be able to tailor our rx to the specific cancer being treated: the elusive personalized medicine. ...Read more

What chromosomal mutation results in alagille syndrome?

What chromosomal mutation results in alagille syndrome?

ALGS: Alagille syndrome (algs) is a complex multisystem disorder involving primarily the liver, heart, eyes, face, and skeleton. The two genes in which mutations are known to cause algs are jag1 and notch2. Mutations in jag1 are known to cause about 94%-96% of cases of algs. Mutations in notch2 are known to cause algs in 1%-2% of individuals. ...Read more

What is a hereditary hemochromatosis DNA mutation?

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

Mutation (Definition)

In genetics, a mutation is a change in the nucleotide sequence of the genome of an organism, virus, or extrachromosomal genetic element. Mutations result from unrepaired damage to dna or to RNA genomes (typically caused by radiation or chemical mutagens), from errors in the process of replication, or from the insertion or deletion of segments of dna ...Read more


Gene (Definition)
