The bill H.639 relates to the privacy of genetic data and introduces new requirements for consumers who wish to pursue civil actions against direct-to-consumer genetic testing companies or service providers. Specifically, it mandates that before initiating a civil action for alleged violations of certain provisions, consumers must send a written notice to the company detailing the alleged violation. This notice must include as many specifics as possible regarding the issue at hand.

Furthermore, the bill establishes a 60-day period during which the company or service provider has the opportunity to address and cure the alleged violation after receiving the notice. If the violation is not resolved within this timeframe, or if there is a disagreement about whether it has been cured, the consumer is then permitted to proceed with the civil action. Notably, the bill clarifies that this cure period does not apply to other types of alleged violations under the same subchapter.
