What Is Mateo's Complete Genetic Story?
Can your team assemble every piece of evidence into one clear, well-supported genetic story for Mateo?
💡 Mateo's case is isolated, nonsyndromic, multifactorial CL/P with IRF6 as the exemplar gene, and the full story runs from clue to gene to variant to to network to proof to population to risk to treatment to ethics.
Prerequisite check
- Bioethics is structured reasoning about what we should do in medicine, not just what we can do.
- A edit changes only the patient and is not inherited; a edit changes , egg, or sperm and is inherited by all descendants, which is why is broadly restricted.
What you will learn
Goal: Assemble the full genetic workup into a structured that connects clue, gene, variant, , network, proof, population, risk, treatment, and ethics into one coherent argument.
- Synthesis means combining many separate findings into one coherent whole; the is the genetics team's destination.
- Mateo's working diagnosis is isolated, nonsyndromic, multifactorial CL/P, with IRF6 the exemplar gene (coding variants cause syndromes; the regulatory SNP rs642961 lowers IRF6 in nonsyndromic risk).
- IRF6 gives : one good copy is not enough for normal development.
- Mateo's family is empiric and multifactorial, roughly 2 to 5%; molecular fixes are only; ethics turns on vs and equity.
Model: The chain: every piece the team gathered
Each link below was a lesson, and the turns this list into one connected argument. Clue: an , told apart from a syndromic one because are the tell for Van der Woude. Gene: IRF6 on 1q32.2. Variant: coding variants (such as R84C or truncations) cause syndromes, while the common regulatory SNP rs642961 lowers IRF6 by breaking an AP-2alpha site. : IRF6 has a and a , and gives . Network: IRF6 works with GRHL3 and of p63 to build the so palatal shelves fuse. Proof: and rescue in mouse and zebrafish prove IRF6 is causal. Population: risk variants and their strength differ by ancestry (8q24 strong in Europeans, weak or absent elsewhere; rs642961 fails to replicate in African-ancestry samples). Risk: the family is empiric and multifactorial, roughly 2 to 5%. Treatment: molecular fixes work in animals only, all . Ethics: vs , and equity of access, frame whether to act.
Mateo's case pulls these together into one diagnosis: an isolated, nonsyndromic, multifactorial lip and , with IRF6 standing as the exemplar gene of the pathway behind it.
Explore (work the model before reading on)
- For each of the ten links, write the single most important sentence in your own words.
- Which two links are the strongest evidence that IRF6 actually causes clefting, not just associates with it?
- Draw an arrow diagram connecting gene to to network to phenotype (). Label each arrow with what happens at that step.
- Mateo's case is nonsyndromic, so we lean on multifactorial risk, not a single Mendelian variant. Explain how the population link and the risk link fit together for his family.
- Your report will be read by the developmental, anatomical, and clinical teams. Which one piece of the genetic story is most important for each of those teams to know, and why?
Guided notes
Building the Domain Report
- The gene is ____, on 1q32.2, found by following the clues.
- The has two domains, and gives ____ (one good copy is not enough).
- The risk paragraph must use empiric, ____ risk of roughly 2 to 5%, not a 50% Mendelian number.
Naming the case and the handoff
- Mateo's working diagnosis is an isolated, ____, multifactorial lip and , with IRF6 as the exemplar gene.
- End the report with what genetics CANNOT answer alone, which is the ____ to the developmental, anatomical, and clinical teams.
Reading the Research
- Skim the title and abstract first to get the gist.
- Circle the one sentence that states the main claim.
- Box the evidence the authors give for that claim.
- Mark one sentence that confuses you, and move on.

- Read the Model and answered the Explore questions.
- Filled in the guided notes in my own words.
- Defined the new vocabulary with an example.
- Built the producible: 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.
- Wrote my Claim, Evidence, and Reasoning exit ticket.
Exit ticket (Claim, Evidence, Reasoning)
- Claim: In one sentence, what is Mateo's complete genetic story?
- Evidence: Cite the two links you consider strongest, for example the -and-rescue proof and the ____-to- mechanism.
- Reasoning: Explain how those two links together support your one-sentence claim that this is an isolated, nonsyndromic, ____ with IRF6 as the exemplar gene.

Where this leads: careers
What's next: The genetics team has now assembled Mateo's complete molecular story, from first clue to ethics. But genetics cannot finish his care alone. We hand the story across to the developmental, anatomical, clinical, and experimental-design teams, so each domain can do its part on how this gene shapes the , the face, the surgery, and the .
