| Primary Identifier | MGI:7852715 | Allele Type | Endonuclease-mediated |
| Attribute String | Modified isoform(s) | Gene | Arpp21 |
| Inheritance Mode | Not Specified | Strain of Origin | C57BL/6N |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | CRISPR/cas9 mediated recombination using guide RNAs resulted in the deletion in exon 5 causing a frame-shift in the open reading frame of the long isoform. Increased expression of the short isoform was detected in thymocytes. |
