What Is Mateo's Complete Genetic Story?
Genetics domain · Lesson 20 of 20 · Medical Interventions (MI), with PBS overlap
Today's goal: Assemble the full genetic workup into a structured Domain Report that connects clue, gene, variant, protein, network, proof, population, risk, treatment, and ethics into one coherent argument.
This is a model of the work you should turn in. Use it to check your own: match the structure and the level of detail, do not copy it. Your wording should be your own.
Mateo's complete genetic story:
- Clue: His cleft is isolated and nonsyndromic; no lip pits ruled out Van der Woude.
- Gene: IRF6, on chromosome 1q32.2, is the exemplar gene of the pathway.
- Variant: Coding variants cause syndromes; the common regulatory SNP rs642961 lowers IRF6 in nonsyndromic risk.
- Protein: IRF6 has a DNA-binding and a protein-binding domain; loss of function gives haploinsufficiency.
- Network: IRF6 works with GRHL3, downstream of p63, to build the periderm.
- Proof: Knockout and rescue in mouse and zebrafish prove IRF6 is causal.
- Population: Risk variants and their effects differ by ancestry, so risk scores do not transfer.
- Risk: The family's empiric, multifactorial recurrence risk is roughly 2 to 5%.
- Treatment: Molecular fixes exist in animals only and are all preclinical.
- Ethics: Somatic vs germline and equity of access frame whether to act.
Handoff: Developmental team, the key fact is that IRF6 drives periderm differentiation for fusion. Anatomical and surgical team, the structure to repair is the unfused lip and palate from failed shelf fusion. Clinical team, the family needs the 2 to 5% empiric recurrence risk and their options. Genetics cannot finish his care alone.
This model shows the level of evidence and organization needed to complete: A condensed, fully connected version of the ten-link Domain Report ending in a cross-domain handoff.
- State the question and method.
- Present the observations and data with units.
- Explain the result, limitations, and next investigation.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: One arrow diagram connecting gene to protein to network to cleft, with each arrow labeled.
The finished product above did not appear all at once. Here is the path from the question to the turned-in work, so you can follow the same steps.
- 1Start from today's question: Which items are direct case facts?
- 2Work the Model and the Explore questions to reason it out before writing anything.
- 3Pull the specific evidence the product needs from the reading and any database you used.
- 4Write it up in the required format: Produce the . Write ten short paragraphs (one per link), in order, each grounded in at least one citation, then add a closing Handoff paragraph telling the developmental, anatomical, and clinical teams the one genetic fact each most needs. Target one to two pages; every claim must trace to a piece in the chain.
- 5Check it against the rubric, then submit.
| Criterion | Proficient | Developing | Beginning |
|---|---|---|---|
| Complete | Every required part of the artifact is present and filled in. | Most parts are present, but one is missing or left blank. | Several parts are missing. |
| Accurate | The science and data are correct and match the evidence. | Mostly correct, with a small factual slip. | Key science or data is wrong. |
| Scientific reasoning (CER) | States a claim, backs it with specific evidence, and explains the reasoning. | Has a claim and evidence, but the reasoning is thin or missing. | Gives an answer with no evidence or reasoning. |
| Professional communication | Clear, organized, and labeled the way a clinician or scientist would write it. | Readable but disorganized or missing labels. | Hard to follow. |
| Submitted | Turned in through the route named under Submit here and confirmed. | Turned in, but in the wrong place or unconfirmed. | Not turned in. |
- CompleteProficient: Nothing is left blank: the model fills every part of "Produce the Domain Report. Write ten short paragraphs (one per link), in order, each grounded in at least one citation, then add a closing Handoff paragraph telling the developmental, anatomical, and clinical teams the one genetic fact each most needs. Target one to two pages; every claim must trace to a piece in the chain.".
- AccurateProficient: Every number and claim matches the case evidence.
- Scientific reasoning (CER)Proficient: It names a claim, cites the specific evidence, and explains the reasoning, not just the answer.
- Professional communicationProficient: It is organized and labeled like a real chart note.
- SubmittedProficient: It would be attached to your class form or handed in, and confirmed.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.
Tap an answer to see the full explanation. Nothing is recorded or graded.
It builds this reusable test skill: Synthesizing a multi-step genetic workup into one supported claim.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
