Some cases (such as intronic variants, which cannot be translated to VRS) fail to generate pre-mapped VRS objects. Currently, if a pre-mapped VRS object cannot be generated, that variant is not represented in the mapper output at all. Each attempted variant should be represented, whether or not it has a pre-mapped VRS object.
