| molecularNote | Exon 17 was replaced with a modified exon in which nucleotide substitutions (GAC to GCT) result in the amino acid substitution of alanine for aspartic acid at position 761 (D761A). An FRT-flanked neo cassette was also inserted but Flp-mediated recombination removed the neo cassette. |
