| Genetic information | The null mutation was generated by introducing a hygromycin cassette in the presenilin 2 gene, thus disrupting the open reading frame. |
| Phenotypic information | Presenilin 2-deficient mice are quite normal, in contrast to presenilin 1-deficient mice (see EMMA strain EM:00303). So far only mild hemorrhage in the lung and some mild fibrosis have been observed. When crossed to the presenilin 1 deficient mice the double mutant progeny show early lethality (E9.5) and a full notch-deficient-like phenotype (Herreman et al., 1999; Proc Natl Acad Sci U S A. 96:11872-7). |
| Breeding history | Backcrossed 14 generations to C57BL/6. |
