CRISPR-CasDisclaimers:
•CRISPR-Cas-mediated “genome editing”is arapidlyemerging technology.Although thecorehas demonstrated successful invivotargetcleavageinmouseembryosin alimited numberof experiments, notalltargetsmayinducegenomeediting equallywell,andsotheGTTRcannotguarantee successful cleavage/editing. Itistheresponsibility oftheinvestigatortoconfirmwhethermutagenesis and/orgenome editing hasoccurred successfullyin theresultingmice.
•SgRNA-mediated cleavagehasbeen reportedto be pronetooff-targetmutagenesis. Theseevents havebeenobserved in someCRISPR-modifiedmice,although notall CRISPRguideRNAswill behighly pronetothisproblem. TheGTTRdoesnothold responsibilityforoff-targetmutations.
• DNAcleavageoftenoccursatthe1-cell stage,but mayoccur atthe2-cell stageor later. CRISPR- mediatedmutagenesiscanthereforegeneratemosaicanimalswith regardstotheproportion ofcells thatcarryspecificmutations. On the other hand,morethan2typesofmutationsatasingletargetsite can sometimesbeobserved in tissuesfromtheinjected mice.Thus,PCRdetection ofmutationsin livebornmicedoesnot guaranteegermlinetransmission ofparticularmutationsis efficient orpossible (although ittypicallyshould be).
•CRISPR-Cas-mediated mutagenesiscanaffectboth allelesin a1-cell embryo.Thus,increased lethality mayresultfromtargetingessential genes,reducing yield of livebornpupsand/orcorrectlytargeted
pups
• Micewill bereleased/shipped to theinvestigatoronlywhenpaymentfortheprojecthasbeenmade,
