ACMG Guidelines for Variant Interpretation

• The ACMG developed guidelines for the interpretation of sequence variants, in order to provide a consistent and robust approach across clinical laboratories worldwide.
• The guidelines are based on a weighting of different lines of evidence, and allow for critical flexibility in the assessment of variants.
• The guidelines are only intended for use in the interpretation of variants identified in patients with suspected inherited Mendelian disorders, in a clinical diagnostic laboratory setting.
• The guidelines are divided into 8 different categories of evidence, and each category has its own weighting.
• The figure shown in the text, showing the organisation of this evidence into a framework, is a useful tool for understanding the weighting of each line of evidence.
