  1. CR – the Czech Republic,
  2. aFrequency of the rearrangement among other potentially causal LDLR variants (pathogenic or variants of unknown significance) found in the Czech population. Frequency was determined as the percentage of probands carrying the specific rearrangement out of all probands with a pathogenic or VUS LDLR variant recorded in the Czech MedPed database as of 4th March 2022
