Gene Affected Aspartoacylase
Origin TALEN (Left:TCGAGCATCCTTCCCTC, Right:CGTTCCATTGCCAAGTA)targeting the exon4 of Aspartoacylase (Aspa) gene was designed and mRNA coding TALEN was microinjected into F344/NSlc embyo.
Strain characteristics 16-bp deletion in the exon4 of Aspa gene: as a rexult of frameshift mutation, stop codon is produced. decreased expression levels of Aspa gene and ASPA protein. Histopatologically, this strain shows vacuole formation in the brain and spinal cord.
Breeding Conditions maintained by crossing between homozygous rats
