[alkc]

Add this:

  [[splice_donor_5th_base_variant]]
    score = 5
    priority = 4
    string = 'splice_donor_5th_base_variant'

  [[splice_donor_region_variant]]
    score = 5
    priority = 4
    string = 'splice_donor_region_variant'

  [[splice_polypyrimidine_tract_variant]]
    score = 5
    priority = 4
    string = 'splice_polypyrimidine_tract_variant'

  [[coding_transcript_variant]]
    score = 1
    priority = 2
    string = 'coding_transcript_variant'

  [[start_retained_variant]]
    score = 1
    priority = 2
    string = 'start_retained_variant'

  [[sequence_variant]]
    score = 1
    priority = 0
    string = 'sequence_variant'

To all rank models.
