presymptomatic genetic testing

Presymptomatic genetic testing allows for the diagnosis of genetic diseases in individuals who are currently healthy but at risk of developing a disorder later in life. This testing can provide accurate predictive information, enabling early intervention that may prevent irreversible damage and the clinical onset of symptoms. It can also be used for carrier testing to determine the risk of having a child with a specific genetic disorder, aiding in family planning decisions.1

However, presymptomatic testing raises ethical concerns, particularly when no effective treatments exist for the identified conditions. Individuals may receive information about future illness and death with no recourse. Additionally, issues of privacy, potential discrimination in employment or insurance, and the psychological impact of receiving negative genetic information are significant considerations. Governments and communities grapple with balancing individual privacy against the need to inform at-risk individuals and manage healthcare costs.1
