---|---|---|---|---|---|
Strain | Stage | +/+ | +/− | −/− | −/− Phenotype |
Senp1M1 Sumo1+/− | E14.5–E16.5 | 15 | 38 | 16 | all normal |
P0 | 9 | 17 | 9 | 4 stillborn | |
Senp1Gt Sumo1+/− | E14.5–E16.5 | 12 | 22 | 15 | 5 dead/dying |
P0 | 16 | 21 | 7 | 6 stillborn |
The number of embryos or pups from crosses within the Senp1M1 Sumo1 or Senp1GtSumo1 strains listed by Senp1 genotype (WT, +/+; heterozygous, +/−; homozygous, −/−). All individuals were heterozygous for Sumo1 mutation. Sumo1 heterozygosity rescues 100% of Senp1M1 mutants past E14.5. The number of Senp1M1/M1 Sumo1+/− individuals found at birth also matches Mendelian expectations. Most pups nursed and survived more than 1 day. For Senp1Gt/Gt Sumo1+/−, rescue is incomplete, and the majority of rescued pups were found dead on P0.
