  1. B Benign, LB Likely Benign, VUS Variant of Uncertain Significance, LP Likely Pathogenic, P Pathogenic Correct classifications are in bold
  2. These data were anonymous and included learners taking part in the MOOCs who were not part of the evaluation cohort
  3. a Likely Pathogenic would be the correct classification under ACMG criteria alone, however, Pathogenic is correct as per ACGS adaptions
  4. b Variant fabricated as a pedagogical device to scaffold learning
  5. c With the information provided in the exercise, this was the appropriate classification, however, with broader data, VUS would be the correct final classification
