| Genetic information | The Adcy5R419W mouse line was generated on a C57BL/6N background using CRISPR/Cas9-mediated genome editing at the Institut Clinique de la Souris – PHENOMIN (https://www.phenomin.fr/en-us/). Mutations were introduced into exon 2 of the Adcy5 gene (ENSMUSG00000022840), located on chromosome 16. Four mutations were simultaneously introduced into wild-type C57BL/6N embryos (Suppl. information, doi: 10.1016/j.isci.2025.11445). A CRISPR ribonucleoprotein complex - comprising a crRNA (5′-GCCGAGCCTGGATACACTCC-3′; MIT score: 88, as predicted by the CRISPOR website), tracrRNA, and wild-type Cas9 - was co-electroporated with a 128-nucleotide single-stranded donor DNA into fertilized C57BL/6N oocytes. Resulting founders were selected based on genotyping and confirmed by Sanger sequencing. Among these, the c.1255C to T (p.R419W) substitution recapitulates the human p.R418W variant, accounting for the one-residue offset between mouse and human proteins. To prevent Cas9 recutting after homology-directed repair, two silent mutations - c.1236C to A and c.1239G to T - were incorporated to disrupt the PAM sequence. Additionally, the c.1251G to A change introduced a HindIII restriction site to simplify genotyping. |
| Phenotypic information | Homozygous:Genotype distribution among Adcy5 littermates followed Mendelian ratios, and no lethality was observed in homozygous or heterozygous mutants during embryogenesis, at birth, or in the pre-weaning period.Heterozygous:see doi: doi: 10.1016/j.isci.2025.11445 |
| Breeding history | The founder was bred with C57BL/6N wild-type mouse. Heterozygous Adcy5 mutant mice from the selected founder line were backcrossed to the C57BL/6N background for at least 10 generations. All backcrosses were performed on C57BL/6N genetic background and the sperm from F3 heterozygous animals was cryopreserved. |
