Genetic Testing (Definition)

Prenatal testing for genetic problems may be done before or after conception. Testing for spina bifida or Down syndrome is done after a pregnancy is established. Besides the couples listed above, counseling and diagnosis are also recommended for mothers over the age of 35, and those who have received abnormal screening test results, such as alpha-fetoprotein (AFP). For more information about the alpha-fetoprotein test, and when and why you might have it, see alpha-fetoprotein.

Hi, anyone familar with fap/gardner syndrome? I know genetic testing would need to be done, i'm in san antonio tx (what do I do next?)

Familial polyposis: Genetic testing can be used to help diagnose fap. With genetic testing, a small blood sample is taken from the individual with fap and is sent to a special laboratory that studies the apc gene. About 80% of the time a change (also called an alteration or mutation) in the apc gene that leads to fap is found. Nice summary at: http://www2.Mdanderson.Org/app/pe/index.Cfm?Pagename=opendoc&docid=1032. ...Read more

3 early MCs & chromosomal abnrml in all fetuses (no birth), is karyotyping of parents the only genetic testing tht can be done? Names of any other pls

It's the starting pt: Parent study comes first.A person can appear normal if they carry all the proper chromosome material but with part belonging to one chromosome swapped with another.(ie, part of a #15 is on #21) When fertilization occurs, the fetus may get part of the mistake and not the other & be defective.Some of these have a partial chance of normal birth, some would always end up a defect.See a geneticist. ...Read more
