Baylor Genetics Data Breach Investigation

Chimicles Schwartz Kriner & Donaldson-Smith is investigating potential class action claims against Baylor Miraca Genetics Laboratories, LLC, doing business as Baylor Genetics, on behalf of patients, current and former employees, and other individuals whose sensitive personal and health information may have been compromised in a recently disclosed data security incident.

What Happened?

On or around June 15, 2026, Baylor Genetics identified suspicious activity within a portion of its information technology environment. An investigation determined that an unauthorized third party accessed portions of Baylor Genetics’ network and certain data stored on the network between June 11 and June 17, 2026.

Baylor Genetics stated that it secured the affected systems, engaged independent cybersecurity and digital forensic specialists, coordinated with law enforcement and regulatory authorities, and strengthened its monitoring, security controls, and identity and access management. The company completed its review of the affected data on or about July 30, 2026 and began notifying potentially affected individuals on or around August 14, 2026. Baylor Genetics has not publicly disclosed how the unauthorized party initially gained access to its network.

On August 18, 2026, the Texas Attorney General reported that the incident affected 248,430 Texas residents. The Texas filing states that affected individuals were notified by U.S. mail, through a company or special-purpose website, and through broadcast media across Texas.

What Information May Have Been Compromised?

The information potentially involved varied by individual. Based on Baylor Genetics’ public notice and the Texas Attorney General disclosure, the affected information may have included:

  • Names
  • Physical addresses
  • Dates of birth
  • Social Security numbers
  • Driver’s license numbers
  • Passport numbers and other government-issued identification numbers
  • Financial account, credit card, or debit card information
  • Medical-testing information
  • Laboratory test results
  • Health-insurance information

Baylor Genetics has stated that Social Security numbers were potentially involved for a very limited subset of patients. For certain current and former employees, the affected information may have included Social Security numbers, government-issued identification numbers, financial-account information, and other personal identifying information.

Why Is This Important?

The combination of Social Security numbers, dates of birth, government-issued identification numbers, financial-account information, medical-testing information, laboratory results, and health-insurance information may expose affected individuals to an increased risk of identity theft, medical identity theft, insurance fraud, financial fraud, and targeted phishing schemes.

Medical-testing and laboratory information is particularly sensitive because, unlike a password or payment-card number, health information cannot simply be replaced after it has been exposed. Genetic and diagnostic information may also reveal private details about an individual’s health, medical history, or testing that the individual reasonably expected would remain confidential.

What Should You Do?

If you received a data breach notification from Baylor Genetics, underwent genetic or laboratory testing processed by Baylor Genetics, or are a current or former Baylor Genetics employee, you may have been affected by this incident.
