| AVT1 deletion | Deletion of AVT1 accelerates the development of age-induced mitochondrial dysfunction without effecting the kinetics of vacuolar acidity decline and prevents the suppression of mitochondrial dysfunction by VMA1 and VPH2 overexpression without affecting vacuolar acidity. AVT1 deletion decreases mean, median and maximum lifespan by 21, 22, and 12%, respectively [23172144]. | Yeast | -20.6 | -22.4 | -11.8 |
| BAS1 deletion | Deletion of BAS1 increases replicative lifespan by 30% in the alpha strain [16293764; 19030232]. | Yeast | +30 | — | — |
| BMH1 deletion | Deleting BMH1 extends chronological lifespan by 25% and is associated with activated stress response, decreased ROS levels and increased heat-shock-element-driven transcription activity. BMH1 deletion was non-additive with the genetic DR mimetic cdc25 and tor1. Water starvation (a form of extreme DR) extends chronological lifespan of BMH1 mutant even more as it does in wild-type [19805817].

| BNA6 deletion | Deletion of BNA6 (alias QPT1) has no effect on replicative lifespan and is not required for lifespan extension by DR, but is lethal with mutation of NPT1 [11000115]. Deletion of BNA6 decreases chronological lifespan [17110466]. | Yeast | — | — | — |
| Brca1 deletion | Deletion of Brca1 causes senescence in mutant embryos and cultured cells and tumorigenesis and signs of premature aging in adults [12533509]. Brca1 heterozygous seem to have shortened lifespan with 70% of tumor incidence. Lymphoma, but not ovarian and mammary gland tumors, occurs commonly in these animals. After a whole-body exposure to ionizing radiation, Brca1 heterozygous mice have a 3-5-fold higher incidence to ovarian tumors, but not lymphoma, when compared with Brca1(+/+) mice [17420720]. | Mouse | — | — | — |

| Casp-2 deficiency | Loss of caspase-2 resulted in a shortened (10%) maximum lifespan and in enhanced aging-related traits such as impaired hair growth, increased bone loss, and reduced body fat content [17188333]. | Mouse | — | — | -10 |
| CAT5 deletion | Deletion of CAT5 decreases chronological lifespan by up to 50% [17492370] and also decreases replicative lifespan by 30% in the alpha strain [18340043]. | Yeast | -30 to -50 | — | — |
| CCR4 deletion | Deletion of CCR4 increases mean chronological lifespan by 20 - 41% (20, 33, 41) in diploid cells [21447998]. In W303R CCR4 deletion shortens replicative lifespan by approximately 80% and results in temperature sensitivity that is suppressed by SSD1-V. SSD1-V partially suppresses the short-lifespan of ccr4 mutant. CCR4 mutation is synthetically lethal in combination with deletion of MPT5 in the absence of SSD1-V [11805047]. | Yeast | -80 to +20 | — | — |

| Cdkn1a knockout | Deletion of Cdkna1 (alias p21) prolongs the lifespan of telomerase-deficient mice with dysfunctional telomeres and improves the repopulation capacity and self-renewal of hematopoietic stem cells [17143283].
The p21(-/-) strains like the Cdkn1a(tmi/Tyj) exhibits enormous regenerative capacities as it closes ear holes similar to MRL mice [20231440; 21722344]. | Mouse | — | — | — |
| che-11 mutation | Loss-of-function muation in che-11 increases lifespan up to 40% (in Bristol N2) [10617200]. che-11 mutants are dye filling defective, defective in osmotic avoidance and dauer formation, and have irregular amphid cilia [2428682]. | Worm | +40 | — | — |
