Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: A genomic fragment encompassing 350 bp of the putative intron 1 and the majority of the putative exon 2 was replaced with an hprt cassette inserted by homologous recombination. The deleted region encoded 19 of the 24 residues of the signal anchor required for membrane translocation. RT-PCR analysis identified mutant transcript in which the putative exon 1 spliced to the putative exon 3. This aberrant splice event results in a frameshift and ultimately a premature stop codon.
