Thank you for addressing the issue of health with certainty as the progress of medical science Some genetic and also non-genetic diseases occur as a result of a change in DNA composition, whether it is a decrease, increase or replacement of one of the nucleic acids by another, and this is called a mutation. To do gene analysis, doctors look for this mutation "to mean any change in the composition of the nucleic acid" or otherwise or otherwise make sure the sequence of DNA is healthy and does not increase or decrease or alter.

Yep, for genetic diseases, doctors will sequence your DNA to determine what errors have occurred that cause the symptoms.
Yes @justtryme90
Gene and DNA testing is usually done in three steps:
2 - Reading DNA sequences with special tests may sometimes be complicated.
3 - Comparison of the result of this examination with a healthy copy of the gene studied, and due to some complications in reading the DNA sequence due to the size of the gene to be examined or other things, the laboratory may examine a specific part or parts of the gene to make sure that it is sound and choose these other parts based on previous research Indicates that this segment is abundant in mutations compared to other parts. Therefore, it should be noted that the examination of the gene does not necessarily examine all genetic matters of the disease, but may be analysis is a partial analysis and not a complete analysis.
