How to identify disease genes?

Question

What are the types of diseases tat can be tested on?
How are the tests done/genes tat be tested?

Answer 1

Theoretically, any disease gene can be located and identified, as long as the sequence of the gene is known. In short, "disease genes" are those that have an abnormal sequence, leading to production of an abnormal protein that is defective or non-functional in some way -- these abnormal gene sequences are the basis of hereditary disease. These gene sequences can also be targeted with fluorescent antibodies that will bind only that specific sequence, and thus they will light up a neon color (microscopically) if that disease gene is present. That's basically the simplified explanation of how geneticists identify abnormal disease genes.

Answer 2

every type of disease can be tested on, the human genome project spent years mapping the human gene list and identifying what should be there and they know that they could splice genes and repair most hereditary problems, but they need more access to stem cells for study and the religious right in the united states wont allow that. they could simply take every inutero baby and test it for any bad genes, then splice those genes with the good parts from stem cells, and return the baby to the uterus, repaired. it will keep taking longer and longer to get to that state unless we are allowed to use stem cell research and practice on human or animal inutero infants.
