Birth defects : Something you are born withGet a more detailed answer ›
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
Yes: It is a defect present from birth, yes. Would i call it a birth defect, no. It is a genetically derived abnormality in the metabolism of hemoglobin that results in sickling of the red cells under some circumstances. As a metabolic disease, it is inherited in a similar fashion to pku or cystic fibrosis. The term birth defect is more appropriate for a kid with malformation of an organ or body part. ...Read more
Pcr-FISH-karyotype: There are 3 main types of genetic tests. The old standard is to take a blood sample from the hip (marrow) and grow cells to look at all the chromosomes (karyotype). It is a 'broad strokes' look but not as sensitive as the others. A fish test looks at blood cells with 'probes' to the known genetic changes (moderately sensitive) and a PCR test is a 'molecular' test of the dna (very sensitive). ...Read moreSee 1 more doctor answer
Help please? What is gene therapy and how might it be used as a treatment for cancer or for genetic disorders?
Gene therapy 4future: Gene therapy is still experimental. In the future it may help treating a disorder by inserting a gene into patient’s cells instead of drugs or surgery. Although it is promising option for some diseases (some inherited disorders, some types of cancer, ), there are still risks and it is still in studies to be sure it will be safe and effective. It is not tested for diseases that have no other cures. ...Read more
Where can I get gene therapy or a genetic test for heredity neuropathy with liability to pressure palsies?
Your doctor has to : Document recurrent focal compression neuropathies with a family history consistent with autosomal dominant inheritance, in which each child of a person with hnpp has a 50% chance of having it ; request a chromosomal microarray from the lab on your insurance company's list. 80% of cases are from a deletion of the pmp22 gene on the short arm of chromosome 17; 20% a from a mutation in pmp22. ...Read more
Can you tell me how could gene therapy differ from traditional therapy in terms of treating genetic disorders in a patient?
Yes, but .....: Clinodactyly is a curve of one or more fingers, which is pretty common, especially for the pinkies, and no big deal at all. Technically it's a minor birth defect and usually not a sign of any problem. But sometimes it's one component of a rare genetic syndrome, like wahab syndrome (http://omim.Org/entry/615170) or a more common one, like down syndrome. I have a little clinodactyly myself! ...Read more
Nope.: Genetic prenatal testing can detect many chromosomal or microscopic dna defects - but it cannot prevent birth defects! 2-4% of all newborns will have a minor or major birth defect and the vast majority of those have unknown genetic underpinnings at this time, although many of us are working to change that. Take Folic Acid 1-5 mg daily to prevent 75-95% of major neural/cardiac fetal anomalies! ...Read moreSee 2 more doctor answers
Gene therapy: The problem with gene therapy is that the agent used to insert or remove a dysfunctionaal gene can alter dna in a way that could result in causing cancer. So far the most specific way to alter genes that has been deveolped is a zinc finger endonuclease (sangamo pharm.). They are studying ways to correct multiple types of abnormal genes that cause human diseases. ...Read more
