Ethics of genetic data
ETHICS DAY If your DNA reveals a risk, do your relatives have a right to know? Genetic information is strange because it is partly shared. A result about me is partly a result about you.
This was the hardest Monday so far and the first one that felt personal rather than academic. I argued for individual privacy and then had to sit with the fact that under my own rule, someone could learn they carry something serious and say nothing to a sibling who could act on it. I did not resolve it. My CER says so, and Mr.
Mendoza said an honest unresolved position beats a tidy fake one.
AT HOME, THE NIGHT BEFORE WED OCT 21 DNA, genes, and protein DNA structure, chromosomes, genes, then the central dogma: DNA to RNA to protein, by transcription and translation. Then how a mutation changes a protein and can cause disease.
I built the pre-lab mutation plan for tomorrow: a nine-base template, the mRNA it transcribes to, the amino acids it translates to, and the point mutation I planned to introduce. Doing it on paper first meant tomorrow was checking my work rather than guessing.
Turned in: pre-lab mutation plan → recorded in Class Records

- • A genetic test is different from any other medical test in one crucial way: your DNA is shared with your biological family. If a test reveals you carry a BRCA gene variant linked to breast , your sister may carry it too.
- • The question today is: does your sister have a right to know? And does your doctor have an obligation to tell her?
- • Legally, in most places, the answer is no. Your genetic information belongs to you. But ethically, the question is genuinely contested. Relatives who could take preventive action and are not told might argue later that they deserved to know.
- • Pick a side and defend it. Wednesday we move from ethics to mechanism: how does DNA actually make a , and what happens when it goes wrong?
- • GINA (Genetic Information Nondiscrimination Act) prohibits discrimination in health insurance and employment based on genetic information, but does not require disclosure to relatives.
- • A patient's information may have medical relevance for first-degree relatives (parents, siblings, children), creating a tension between individual privacy and family benefit.
- • Genetic counselors are healthcare professionals who help individuals and families understand and navigate the implications of genetic test results.

A genetic result is partly shared with relatives, so deciding who may see it is an ethical problem that ordinary private lab tests never create.
A smoke alarm detects signs of fire but can also react to burnt toast.
- What does the alarm detect?
- What creates a false alarm?
- What evidence is needed before declaring a fire?
A screening signal changes what to investigate next; it does not automatically prove the cause.
Biomedical tests have measured performance and biological sampling limits that a household alarm does not capture.

Driving question: If your DNA test reveals a serious inherited risk, do your parents, siblings, and children have a right to be told, even if you say no?
What you already know: A trend describes direction, speed, and position relative to the , so reading the trend rather than any single value tells you whether a chronic condition is improving or worsening, because one reading can be distorted by a meal, stress, or lab error.
New idea: A genetic result is partly shared with relatives, so deciding who may see it is an ethical problem that ordinary private lab tests never create.

- Observe or measure the relevant feature in Ethics of genetic data.
- Organize the observation with a stable evidence ID.
- Apply this rule: A screening signal changes what to investigate next; it does not automatically prove the cause.
- Choose the option the evidence supports and state the limit of the conclusion.
Real biomedical example: If your DNA test reveals a serious inherited risk, do your parents, siblings, and children have a right to be told, even if you say no?
What the evidence supports: E1-E3 and F1 support the daily take-home when the response meets the stated success criteria.
What it cannot prove: The package does not support claims beyond this lesson's or any real patient diagnosis.
- • DNA: The molecule that stores genetic instructions in a twisted double helix, with paired bases that spell out the code for building an organism.
- • : A tightly coiled package of DNA wrapped around proteins that carries genes; humans normally have 46 of them, arranged in 23 pairs.
- • gene: A stretch of DNA that codes for a product (usually a ) and carries an instruction for the cell.
- • : One of the alternative versions of a gene found at the same spot on a , like the blue or brown options for eye color.
- • : A folded chain of amino acids that a gene's instructions are used to build, serving as the cell's machines and structural building blocks.
- • : The first step of making a : copying a DNA gene into messenger RNA.

PLTW-PBT-2026-10-20 · Simulated classroom evidence scenario
Your role: biomedical investigator
Decision: Your team must decide what the evidence from Ethics of genetic data supports before submitting the claim-evidence-reasoning response named on the lesson page.
- • Choose the strongest supported explanation.
- • Choose the next evidence to collect.
- • Hold the decision because the evidence is insufficient.
Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the claim-evidence-reasoning response.
Claim ceiling: The supplied lesson evidence can support an observation, pattern, classroom mechanism, or next-step decision about Ethics of genetic data. It cannot by itself prove causation, establish a real clinical diagnosis, or justify action outside this classroom task.
Reason for review: Your team must decide what the evidence from Ethics of genetic data supports before submitting the claim-evidence-reasoning response named on the lesson page.
Context: A genetic result is never only about one person, so the ethics of who sees it are different from the ethics of any other lab test.
- • T1: Read the prompt: If your DNA reveals a risk, do relatives have a right to know?
- • T2: List one argument for disclosure and one for individual privacy.
- • T3: Choose a side and connect it to shared genetic information.
- • T4: Argue your claim in your group with one reason and one example.
- • T5: Post a written CER with your position and reasoning.
- • E1: GINA (Genetic Information Nondiscrimination Act) prohibits discrimination in health insurance and employment based on genetic information, but does not require disclosure to relatives.
- • E2: A genetic result is partly shared with relatives, so deciding who may see it is an ethical problem that ordinary private lab tests never create.
- • E3: I can weigh genetic privacy against relatives' interests.
Measurements: Use only the measurements, units, graph, or counts supplied in today's task. No additional patient measurement is implied.
Figure finding: Teaching diagram for Ethics of genetic data. Trace the labeled observation or evidence sequence before choosing an explanation. This is a teaching model, not patient or experimental data.
Uncertainty: This is a composite classroom scenario. Missing history, measurements, or confirmation tests remain unknown and limit the conclusion.
Mean = sum of values / number of values. Median = middle ordered value. Range = maximum - minimum.
For 2, 4, 4, and 10: mean = 20 / 4 = 5, median = 4, and range = 10 - 2 = 8.
Mean, median, and range keep the measurement unit. Order the values before finding the median.
Calculate the requested summary for today's supplied values, then write what it reveals and what it hides.
Students often think Students often assume your medical records are 100 percent private, so a genetic result is yours alone to keep or share.. The trap: The trap is treating DNA like a blood-sugar reading. Your sequence is half-shared with each parent, sibling, and child, so a result about you is a partial result about them, which is exactly why the privacy question is so hard.
Parallel scenario (a model, not today's answer): A person tests positive for a serious sexually transmitted infection such as HIV. Should their past partners be told, even if the patient would prefer that no one is contacted?
Claim: A patient who tests positive for a serious sexually transmitted infection should be strongly encouraged to allow past partners to be notified, and public health should offer confidential partner notification, but the patient should not be publicly named without their consent.
Evidence: Infection information is partly relational, because a positive result also points to a risk that specific past partners may already be infected and not know it. Many U.S. states run confidential partner notification programs in which a health worker contacts partners without revealing the patient's name. Laws protect people who test positive from certain kinds of discrimination, but those protections do not, by themselves, require a patient to personally tell every partner.
Reasoning: Because the risk is shared, past partners could benefit medically from learning they should be tested and, if needed, treated early, which supports notification. At the same time, the result is sensitive personal health information, so privacy and autonomy support letting the patient control how their own name is used. The balanced position uses confidential partner notification, which lets partners learn their risk while shielding the patient's identity, so both the health benefit to others and the patient's privacy are respected rather than one being sacrificed for the other.
This model shows the level of evidence and organization needed to complete: A short written argument, modeled on a parallel scenario, that takes a side on whether a patient who tests positive for a serious infectious disease should have past partners notified, with reasoning that weighs relational health information against patient privacy. It models the Claim, Evidence, Reasoning format and depth without answering today's genetic-data prompt.
