Which element explains whether a detected variant is pathogenic or benign?

• A. Indication
• B. Methods
• C. Variant interpretation
• D. Follow-up recommendations

Answer: (C)

Evaluating whether a detected genetic variant is pathogenic or benign hinges on variant interpretation. This step brings together diverse lines of evidence—how common the variant is in the general population, predictions from computational tools, functional studies, how the variant segregates with disease in families, and relevant published data—and applies standardized criteria (such as ACMG/AMP guidelines) to classify the variant as pathogenic, likely pathogenic, benign, likely benign, or of uncertain significance. This interpretation directly informs clinical decisions, including patient management, surveillance, and testing of relatives. Other elements serve different roles: indication explains why testing was done, methods describe how the test was performed, and follow-up recommendations outline next steps after results are reported.
