Figure 1 Distribution of Variant-Classification Comparisons according to the Extent of Differences across a Five-Tiered Classification Scheme (A) Intra-laboratory concordance between laboratory and ACMG-AMP classification systems. This graph compares each site’s use of the ACMG-AMP rules to their own laboratory classification methods. (B) Inter-laboratory concordance of 97 variants. This graph compares the same calls, based on either the ACMG-AMP rules or the site’s rules, between laboratories. (C) Inter-laboratory concordance after consensus efforts. This graph shows a final comparison of calls between sites after consensus-building efforts.

Figure 2 Distribution of 99 Variants Submitted for Assessment Gray outlines illustrate the distribution of variant classifications submitted for assessment. Green bars indicate those calls that were agreed upon after initial review, blue bars indicate those calls agreed upon after email exchange, and black bars indicate those calls agreed upon after discussion on conference calls.
