• Classification of mutations is based on PCR products generated as described in Figure 2.

• a Defined by a diagnostic PCR product that is indistinguishable in size from the parental 1.5-kb product (see Figure 2). Nucleotide sequences of 27 such clones are presented in Figure 3.

• b Defined by a PCR product that is visibly larger than the parental 1.5-kb product (see Figure 2).

• c Number of clones recovered for each category.
