clinical variant classification

The systematic assignment of clinical significance levels to genetic variants based on evidence criteria.

Full Definition

Clinical variant classification is the process of categorizing genetic variants according to their clinical significance using standardized evidence frameworks, typically following ACMG-AMP guidelines. Classifications include pathogenic, likely pathogenic, variant of uncertain significance (VUS), likely benign, and benign categories. This process requires evaluation of multiple evidence types including population data, functional studies, computational predictions, and clinical observations. Accurate classification is essential for appropriate clinical interpretation and patient management decisions.

Usage

Usage note: Should follow established guidelines such as ACMG-AMP recommendations for consistency.
