Unknown Story

One con to consider with genetic testing is that it's possible that not all variations that raise a person's risk of contracting a disease or condition are known.

For example according to the NIH article "Direct-to-consumer genetic testing – advantages and pitfalls", “DTC genetic testing often does not provide conclusive results on whether the consumer will develop a disease or not. Most genetic tests performed by DTC companies are limited to few major genetic variants related to the phenotype of interest, which leads to poor discriminatory power.”

According to the article on Mayo Clinic Proceedings, “Furthermore, buried in these user agreement forms were provisions that allowed DTC companies to retain and use customer data with impunity This meant that companies could sell aggregate data to third parties or use consumer's data for research without their awareness.”

Another con to genetic testing is that it can come with some privacy concerns.

Finally the last con to genetic testing is The Genetic Information Nondiscrimination Act (GINA) only prohibits healthcare providers from utilizing genetic information about you in coverage and rating decisions. It does not apply to other types of insurance. Therefore, the results of a genetic test may have an impact on your decision to purchase particular types of health insurance.

According to the article on Mayo Clinic Proceedings,“However, GINA does not cover certain other types of insurance. Receiving a genetic testing result may impact your purchase of life, disability, and long-term care insurance.”
