Free CGC Genomic Testing & Interpretation Questions and Answers

Question 1

What is the main purpose of genomic testing?

Accepted Answer

To identify disease-related genetic variants

Answer

Genomic testing identifies genetic variants that may contribute to disease or inherited traits.

Question 2

Which type of test examines many genes at once?

Accepted Answer

Panel testing

Answer

Panel testing evaluates multiple genes associated with a condition or symptoms.

Question 3

What does a variant of uncertain significance (VUS) indicate?

Accepted Answer

Its significance is not currently known

Answer

A VUS means the genetic change has unknown impact on health or disease risk.

Question 4

Which result indicates a disease-causing mutation?

Accepted Answer

Pathogenic

Answer

In genetics, a 'pathogenic' variant or mutation is one that is known to cause disease. This classification indicates a clear link between the genetic change and a specific health condition. Other options like benign or likely benign suggest no disease causation, while VUS (Variant of Uncertain Significance) means its impact is not yet known.

Question 5

Which technology is commonly used in genomic sequencing?

Accepted Answer

Next-generation sequencing

Answer

Next-generation sequencing (NGS), also known as high-throughput sequencing, is a revolutionary technology that allows for rapid and cost-effective sequencing of entire genomes or specific regions. It has become the standard method for genomic sequencing due to its ability to generate vast amounts of DNA sequence data simultaneously. Ultrasound and MRI are imaging techniques, and a blood pressure monitor is a diagnostic tool, none of which are used for genomic sequencing.
