| molecularNote | A stop codon was introduced into exon 3a preventing the production of the A transcript. A floxed neo cassette was inserted upstream of the modified exon 3a. Exons 4 through 6 and part of 7 were deleted, preventing the expression of the C splice variant. Cre-mediated recombination removed the neo cassette. |
