Mutation detailsA neomycin selection cassette was used to replace a region including the the 5' portion of exon 8 and the 3' portion of exon 9, which encodes a lysine residue essential for binding pyridoxal 5'-phosphate (PLP). RT-PCR analysis showed an absence of message in hemizygous mutant embryos. (J:58508)
