| molecularNote | Exon 2 was replaced with one in which nucleotide substitutions result in the amino acid substitutions of glutamine for tryptophan at position 2 (W2Q) and alanine for arginine at position 97 (R97A). Cre-mediated recombination removed the floxed neo cassette inserted downstream of the modified exon 2. |
