Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: The first five exons were replaced with a PGK-neomycin resistance gene via homologous recombination. The genetic disruption resulted in complete loss of acid endonuclease activity in mouse embryonic fibroblasts and E15.5 livers from homozygous mutant embryos. (J:89469)
