Mutation detailsA PGK-neo cassette was inserted to delete a region spanning from the middle of exon 3 through exon 6. This deleted region encodes the essential homocysteine binding domain. Reduced levels of transcript were observed in extracts from the liver and kidney of heterozygous mutant mice. Enzyme activity levels in heterozygotes were found to be approximately 60% of wild-type.
