Gentests
Gentests are laboratory procedures that analyze DNA, RNA, or chromosomes to identify genetic variations that may influence health, development, ancestry, or drug response. They are used in clinical, research, and consumer contexts to detect inherited conditions, assess disease risk, determine carrier status for recessive disorders, guide treatment choices through pharmacogenomics, and provide information about ancestry or paternity.
Common methods include targeted gene panels, whole-exome sequencing, and whole-genome sequencing, as well as genotyping arrays
Applications span diagnostic testing for rare diseases, predictive or pre-symptomatic testing for individuals with a family
Limitations include incomplete penetrance, variable expressivity, and the possibility of inconclusive results. Privacy, data security, and
