Why is gene psychotherapy not applicable to non-hereditary conditions?
why only the hereditary ones?
Answers:
Gene therapy specifically target the problems that occur in the path from DNA to protein use contained by a hereditary disease by 'inserting' correct copies of genes in place of the incorrect, inherited ones. A non-hereditary condition does not arise directly from a problem beside the gene in the DNA, so gene therapy isn't useful nearby.
For example; Severe Combined Immunodeficiency Disorder (SCID), mostly an X-linked hereditary disorder, is a disorder where the white blood cells responsible for recognising and attacking foreign invaders (T-cells) hold a faulty receptor protein.
This protein is supposed to help the T-cells develop properly, so without a working copy, the body can lose one of its best ramparts against infections, and the person can become dangerously sick.
A gene-therapy for SCID was to use a modified virus to infect the T-cells, hopefully replacing the defective copy near the correct version of the receptor gene.
Gene therapy works at the level of your DNA, so for example if you consider Pneumococcal Pneumonia. This is an infection cause by a bacterium so we find that it's better to deal with these things by eradicating the offending infectious agent as opposed to doing anything to our genes.
