Common Types of Genetic Testing Errors and Malpractice

Genetic malpractice occurs when a medical geneticist, counselor, or laboratory fails to meet the standard of care, leading to errors such as sample contamination, misinterpretation of data, or failure to communicate critical results. These errors generally fall into three categories, each with different causes and very different consequences for the patient.

A false positive, a result that incorrectly indicates a patient has a genetic condition or mutation that is not actually present, can trigger a cascade of unnecessary and irreversible medical decisions. For example, a woman who receives an incorrect positive result for a BRCA gene mutation may undergo a prophylactic mastectomy, the surgical removal of healthy breast tissue, based on a risk that never existed. The physical, emotional, and financial toll of an unnecessary surgery like this is profound.

False Negatives happen when a test fails to detect a condition or mutation that is present. A false negative, a result that incorrectly shows no abnormality, can be equally devastating because it creates a false sense of security. A patient carrying a hereditary cancer gene may forgo the screenings and preventive measures that could have caught the disease early. By the time symptoms appear, treatment options may be far more limited.

Administrative and laboratory errors represent a third category that has nothing to do with the science of interpretation and everything to do with process failures. Sample mix-ups, lost specimens, contamination during handling, and technical failures in sequencing equipment can all produce unreliable results. These are the types of errors that should never happen in a properly managed facility, yet they do.

A medical geneticist malpractice attorney investigates each of these failure points to determine where the standard of care was violated and who bears responsibility. The table below outlines the key differences between these error types.

Error Type	How It Happens	Potential Patient Impact	What We Investigate
False Positive	Misinterpretation of data, flawed assay, contamination	Unnecessary surgery, unneeded treatment, psychological harm	Interpretation protocols, confirmatory testing steps, clinical correlation
False Negative	Missed mutation, inadequate panel, sequencing failure	Delayed diagnosis, disease progression, lost treatment window	Test sensitivity, variant classification, follow-up recommendations
Lab/Administrative Error	Specimen mix-up, lost sample, equipment malfunction	Any of the above, depending on the downstream effect	Chain of custody records, calibration logs, technician qualifications

A lawyer for genetic testing errors will trace the full path from sample collection to final report to identify where the breakdown occurred.

Establishing Liability for Geneticists and Laboratories in Texas

Liability in genetic malpractice cases may extend beyond the ordering physician to include the medical geneticist who interpreted the results, the laboratory that processed the sample, or the manufacturer of defective testing equipment. Identifying who is responsible often requires a detailed investigation into the roles and handoffs between multiple parties. These cases are rarely simple, as blame often shifts between the clinical and technical teams involved in the patient’s care.

The Geneticist’s Duty. A medical geneticist has a direct obligation to accurately interpret complex genomic data and clearly communicate findings and their implications to the patient and the referring physician. If a geneticist misclassifies a variant, overlooks a clinically significant mutation, or fails to recommend appropriate follow-up, that failure can form the basis of a negligence claim. A Texas medical geneticist malpractice lawyer will review the interpretation report, the raw data, and the communication records to assess whether the geneticist met the accepted standard. Thorough scrutiny of these documents often reveals discrepancies that are invisible to the untrained eye.

Laboratory Negligence. The laboratory facility itself can bear liability for technical errors, equipment failures, or violations of federal regulatory standards. Labs performing genetic testing must comply with the Clinical Laboratory Improvement Amendments (CLIA), a set of federal quality standards established under 42 CFR Part 493 that govern everything from personnel qualifications to proficiency testing and quality control procedures. These regulations ensure that every step of the testing process meets rigorous safety and accuracy benchmarks.

Specimen contamination, the introduction of foreign material into a patient’s sample during collection, handling, or processing, can corrupt results entirely. When a lab like LabCorp or Quest Diagnostics fails to follow these protocols, or when a pathologist oversees a flawed process, an attorney for lab negligence can hold the facility accountable.

Genetic Counselor vs. Supervising Physician. We must distinguish the role of a genetic counselor from that of the supervising physician. A counselor typically helps patients understand risk and results but may not independently order or interpret tests. A supervising physician, on the other hand, may bear responsibility for the final clinical decision based on those results. Determining which professional owed the duty, and which one breached it, is central to establishing proximate cause and building a viable claim.

Liability of Surgeons and Ordering Physicians

Surgeons and ordering physicians carry their own distinct liability when they act on genetic test results. A surgeon who proceeds with unnecessary surgery or a major procedure, such as removing an organ based on a genetic report, may be negligent if they failed to independently verify the results or correlate them with the patient’s clinical presentation before operating.

Prophylactic surgery, a preventive procedure performed to remove tissue before disease develops, should not be based solely on a single test result without confirmatory testing, an independent method used to validate the findings by repeating or supplementing the original test. When a physician skips this step and the original result turns out to be wrong, that physician may share liability alongside the geneticist and the lab. Our team examines whether a biopsy or confirmatory testing was ordered, whether the clinical picture supported the surgical decision, and whether oncology and pathology consultations were obtained before proceeding.

The Devastating Impact of Genetic Misdiagnosis on Families

The consequences of genetic errors can be catastrophic, ranging from the birth of a child with a preventable severe disability to the removal of healthy organs or the progression of an untreated terminal illness. Because genetic information often guides decisions that are irreversible, the harm from a single error can reshape an entire family’s future.

A false negative on a prenatal or carrier screening test, for example, may deprive parents of the information they need to prepare for a child with a serious hereditary condition. This lack of knowledge prevents families from arranging necessary medical support or making informed reproductive choices. A missed cancer predisposition can mean a patient loses their best window for early intervention. And a false positive can lead to aggressive, unnecessary treatment that causes lasting physical harm.

When we evaluate a genetic malpractice case, we also consider how a variant of uncertain significance (VUS), a genetic change whose connection to disease is not yet clearly established, may have been presented to the patient. If a VUS was communicated as a definitive diagnosis, that mischaracterization can lead to decisions the patient would not otherwise have made.

The damages in these cases can be extensive:

• Physical harm: Pain and suffering from unnecessary surgical procedures, untreated disease progression, or corrective treatments required to address the original error.
• Financial losses: Lifetime costs of care for a child born with a missed hereditary condition, medical expenses from unnecessary treatment, and lost income during recovery or ongoing disability.
• Psychological and emotional harm: The lasting emotional toll of making irreversible life decisions, such as surgery or decisions regarding the impact on family planning, based on information that was wrong.
• Wrongful death: In the most tragic cases, a missed or delayed genetic diagnosis contributes directly to a patient’s death, giving surviving family members the right to pursue a wrongful death medical malpractice claim.

As experienced genetic malpractice counsel and a Texas medical geneticist negligence lawyer, we work to document every dimension of harm so that the full scope of what a family has endured is presented accurately. In certain cases involving willful disregard of protocols, punitive damages may also be recoverable.

Why Expert Testimony is Critical in Genetic Malpractice Cases

Texas law requires specific expert reports to validate a medical malpractice claim, and in genetic cases, this means testimony from forensic pathologists, geneticists, or molecular biologists who can establish that the error was a breach of the standard of care. Our legal team secures qualified expert reports to build the scientific foundation these cases demand.

Chapter 74 Requirements. Under Chapter 74 of the Texas Civil Practice and Remedies Code, a plaintiff must serve a qualified expert report within 120 days after the defendant files an original answer. This report must identify the applicable standard of care, explain how it was breached, and describe how the breach caused the patient’s injury. The courts enforce these requirements strictly to filter out frivolous suits, making the quality of the expert report a determining factor in the case’s survival.

Failure to meet this deadline results in dismissal. A negligence claim requires precision, and a malpractice lawyer for geneticists understands these timelines and begins identifying and engaging the right experts from the earliest stages of investigation.

Proving Causation. Causation is often the most contested element in genetic malpractice cases. It is not enough to show that a test was wrong. The expert must connect the specific error directly to the harm. For instance, if a hereditary cancer mutation went undetected, the expert must demonstrate that earlier detection would have led to treatment options that could have changed the patient’s outcome. This requires a detailed review of medical records, the original testing methodology, and the patient’s clinical timeline.

Overcoming the “Evolving Science” Defense. Defense attorneys in genetic cases often argue that the science was uncertain or still developing at the time the test was performed, particularly when next-generation sequencing (NGS), a high-throughput technology that analyzes millions of DNA fragments simultaneously, is involved. This argument attempts to reframe a clear error as an unavoidable limitation of the field. A Texas genetic testing error attorney counters this by presenting evidence of what was known and accepted in the scientific community at the time, demonstrating that the error fell below the standard regardless of ongoing advancements.

Our legal team, which includes in-house medical staff and access to a national network of qualified experts, is equipped to build the scientific foundation these cases demand.
