Legend

  • [a] /, cryptic or de novo splice sites; > nucleotide substitutions; (), deletions; [], duplications or insertions. Intronic sequences are in lower case (in blue), exons are in upper case (in green)
  • [b] Shapiro and Senapathy matrix scores were calculated according to an algorithm published previously (1). Maximum entropy and the first-order Markov and weight matrix models were computed as described (2)
