Baylor Genetics has disclosed a cybersecurity incident that may have exposed personal information belonging to some patients and employees, but the company says laboratory operations were not interrupted and genetic testing services continued as normal. The incident was detected around June 15, 2026, after suspicious activity appeared in a limited part of its IT environment.
According to the notice, an unauthorized third party accessed certain parts of Baylor Genetics’ network between June 11 and June 17, 2026. The company then launched a forensic investigation with outside cybersecurity specialists and spent weeks reviewing what data may have been involved and which people were potentially affected. That review was completed on or about July 30, 2026, after which written notices were sent to affected individuals when address information was available.
The data at issue varied by person, but for patients it may have included names, dates of birth, medical testing information, laboratory test results, and possibly health insurance details. In a very limited number of cases, a Social Security number may also have been involved. For current or former employees, the exposed information may have included Social Security numbers, government-issued identification numbers, and financial account information.
Baylor Genetics says it immediately secured affected systems, strengthened identity and access controls, enhanced monitoring, and coordinated with law enforcement and appropriate regulators. The company also said it has not found evidence of confirmed identity theft, fraud, or misuse tied to the incident so far. It added that test results remain accurate and that no testing data or results were altered, so no retesting is necessary.
The notice urges people to watch financial account statements, Explanation of Benefits statements, and credit reports for unusual activity. It also points readers to identitytheft.gov, the Federal Trade Commission, and state attorneys general for help with fraud alerts, credit freezes, and identity-theft complaints. Baylor Genetics has set up a dedicated assistance line at 1-866-200-0985, available Monday through Friday from 9 a.m. to 9 p.m. ET.
