  1. Abbreviations: n, number of alleles sequenced.
  2. Mutations denoted St result in premature stop codons, D denotes large deletions, d denotes one bp deletions resulting in frame shifts, Sp a mutation in a splice signal, and I denotes 2 bp insertions resulting in frame shifts.
  3. aNumbers below the names of mutations represent its position in nucleotides from the start codon. The positions of different mutations are also shown in Figure 1.
