The Hidden Regulatory Variant

Genetics domain · Lesson 9 of 20 · Medical Interventions (MI), with PBS overlap

Today's goal: Students will distinguish coding from regulatory variants and explain how the common nonsyndromic cleft-lip risk variant rs642961 raises risk by disrupting an AP-2alpha enhancer instead of changing the protein.

What a finished product looks like

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.

Counselor's plain-language note
Completes: A two-sentence family explanation distinguishing a regulatory risk allele from a protein-changing mutation.

Counselor's note for the family:

  • This variant (rs642961) does not change the IRF6 protein at all. Instead it sits in a nearby switch region (the MCS-9.7 enhancer) and breaks the spot where a helper protein, AP-2alpha, normally docks, so IRF6 gets turned down in the lip-forming tissue.
  • Carrying the A version is a risk factor, not a guaranteed cause: isolated cleft lip is multifactorial, so this common variant nudges risk up a little and adds to many small factors, rather than guaranteeing a cleft.

Also due today: Keep the language plain enough for a family with no genetics background.

How this was built, step by step

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.

  1. 1Start from today's question: Where is the common, hidden variant?
  2. 2Work the Model and the Explore questions to reason it out before writing anything.
  3. 3Pull the specific evidence the product needs from the reading and any database you used.
  4. 4Write it up in the required format: In the 's note, write two sentences for the family: one explaining that rs642961 does NOT change the IRF6 but turns it down by breaking a switch, and one stating why it is a , not a guaranteed cause.
  5. 5Check it against the rubric, then submit.
How this is graded (rubric)
For: In the genetic counselor's note, write two sentences for the family: one explaining that rs642961 does NOT change the IRF6 protein but turns it down by breaking a switch, and one stating why it is a risk factor, not a guaranteed cause.

How the model answer scores against this rubric
  • CompleteProficient: Nothing is left blank: the model fills every part of "In the genetic counselor's note, write two sentences for the family: one explaining that rs642961 does NOT change the IRF6 protein but turns it down by breaking a switch, and one stating why it is a risk factor, not a guaranteed cause.".

WebXam problem for today's skill

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.

WebXam-style domain: Gene regulation and multifactorial diseaseSelf-check skill: Distinguishing a regulatory risk allele from a protein-coding mutation
The common variant rs642961 sits in the MCS-9.7 enhancer upstream of IRF6. In a binding test, the G version binds the transcription factor AP-2alpha but the risk A version does not. The IRF6 protein sequence is unchanged. How does the A allele raise cleft-lip risk?
