Worked examples: how to reason through CGC questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: The ACMG/AMP criterion PVS1 applies to which type of variant?

  1. A null variant in a gene where loss of function is a known disease mechanism
  2. Any missense variant in a conserved domain
  3. A variant seen in many unaffected controls
  4. A synonymous variant predicted to alter splicing

Answer: A. A null variant in a gene where loss of function is a known disease mechanism

Explanation:

Option A is correct. In the ACMG/AMP framework, PVS1 is very strong evidence meant for null variants, such as nonsense, frameshift and canonical splice-site changes, but only in a gene where loss of function is an established disease mechanism.

Option B is wrong because a missense variant does not clearly abolish the protein, and conservation is different, weaker evidence. Option C is wrong because a variant seen in many unaffected controls points toward benign evidence, not pathogenic. Option D is wrong because a synonymous change is not a null variant, and any splicing effect would need its own supporting evidence.

Rule to remember: ask two questions. Is the variant truly null, and is loss of function how this gene causes disease? Both answers must be yes before PVS1 applies.

Example 2

Question: When counseling a patient from a different cultural background regarding a hereditary condition, the genetic counselor should FIRST:

  1. Assume cultural beliefs will not affect decision-making
  2. Ask the patient about their cultural values and beliefs related to genetics
  3. Proceed with standard counseling and adjust only if resistance is encountered
  4. Request a formal cultural competency consult

Answer: B. Ask the patient about their cultural values and beliefs related to genetics

Explanation:

Option B is correct. Asking about the patient's cultural values and beliefs before you counsel lets you shape the information so it is relevant and respectful, and it treats the patient as the authority on their own views.

Option A is wrong because assuming culture will not matter is itself an assumption, and it can hide beliefs that shape decisions. Option C is wrong because waiting for resistance means the session has already gone off course, and a patient may simply stay quiet instead of objecting. Option D is wrong because a formal consult is not the first step; the counselor can start the conversation directly and consult later if needed.

Rule to remember: elicit before you educate. Explore the person's context first, then adapt your counseling to it.

Example 3

Question: A laboratory reclassifies a previously reported VUS as likely pathogenic. What is the most appropriate next step?

  1. Issue an amended report to the ordering provider so the patient can be recontacted
  2. Wait until the patient asks about updated results
  3. Delete the original report from the record
  4. Reclassify only if a relative also tests positive

Answer: A. Issue an amended report to the ordering provider so the patient can be recontacted

Explanation:

Option A is correct. When a laboratory reclassifies a variant in a way that could change care, it should issue an amended report to the ordering provider, who can then recontact the patient and act on the new classification.

Option B is wrong because it puts the burden on the patient, who has no reason to know a result changed. Option C is wrong because deleting the original report erases the record of what was reported and when, which laboratories and clinicians need for accountability. Option D is wrong because a reclassification rests on accumulated evidence about the variant, not on whether a relative happens to test positive.

Rule to remember: when a classification changes, communicate it through a documented, amended report to the provider.

How to use these practice tests

Start by reading the ABGC exam information and the content outline so you know what is tested and how the exam is delivered. Then take one practice set from each area, using the sets listed above, without notes. Your aim at this stage is a map of weak spots, not a score.

Next, work in blocks by topic. For every question you miss, write one sentence on why the correct option is right and one on why your choice was wrong. Pay particular attention to the reasoning rules behind variant classification, risk calculation and counseling responses, because the same rule shows up in many different questions.

Mix in cancer genetics, prenatal genetics and laboratory genetics once your core areas feel steady, and keep returning to psychosocial and ethical issues, since scenario questions often blend them with technical content.

In the final stretch, sit a long mixed session in a quiet room and time it against the full exam length, so the pace and stamina feel familiar. Our questions are written by us and are not real exam questions, so use them to build reasoning, not to predict content.
