| CIT2 deletion | Deletion of CIT2 has no effect on replicative lifespan [10224252]. | Yeast | — | — | — |
| COQ3 deletion | Deletion of COQ3 decreases chronological lifespan and renders cells respiratory deficient and sensitive to hydrogen peroxide [12586694]. | Yeast | — | — | — |
| CPR7 deletion | Deletion of CPR7 has no effect on lifespan replicative lifespan, but increases chronological lifespan [11361336] | Yeast | — | — | — |
| CTF4 deletion | Deletion of CTF4 results in an approximately 75% reduced mean replicative lifespan [12024027]. | Yeast | — | — | — |
| CYT1 deletion | Deletion of CYT1 increases replicative lifespan by 15% in the alpha strain and decreases replicative lifespan by 20% in a strain. Deletion of CYT1 decreases replicative lifespan and cancels out replicative lifespan extension by HAP4 overexpression. Initially, it was shown that deletion of CYT1 also prevents lifespan extension by 0.5% glucose restriction [12124627], but later it was shown that either 0.5 or 0.05 % glucose restriction increases replicative lifespan of cyt1Delta cells [16311627]. | Yeast | — | — | — |
| DNA2 deletion | Mutants in DNA2 exhibit an accelerated ageing phenotype including extended cell cycle time, age-related transcriptional silencing defects, and nucleolar reorganization, which are all phenotypes of old wild-type cells. Lifespan of DNA2 mutants is extended by expression of an additional copy of SIR2 or by deletion of FOB1 and therefore the lifespan shortening partially suppressed. Three different alleles of DNA2 (dna2-1, dna2-2, and dna2-20) result in a significant shortened lifespan up to 85%. DNA2 mutation shorten the already short lifespan of SGS1 mutants [12024027]. | Yeast | — | — | — |
| DNL4 deletion | DNL4 deletion does not affect lifespan [10521401], although it renders cells defective for non-homologous end-joining [9242411] | Yeast | — | — | — |
| FOB1 deletion | Mutation in FOB1 extends replicative lifespan by 30-50% [10230397]. FOB1 mutation increases replicative lifespan by 25% in the alpha strain and by 10% in a strain [19030232]. FOB1 mutant exhibit an about 20% mean replicative lifespan increase [15722108]. Deletion of FOB1 causes extension in the short life span of the sir2 mutant by around 50% [10521401]. Mutation of the FOB1 gene slows the generation of rDNA circles and thus extends life span by approximately 30% in W303 and 50% in K2307 [10230397]. Even in cells lacking both Sir2 and Fob1, nicotinamide prevents the lifespan extension by DR [16311627]. | Yeast | — | — | — |
| GAL83 deletion | Deletion of GAL83 has no effect on replicative lifespan in S228C [10921902] and general GAL83 mutants have no obvious phenotype [10990457]. | Yeast | — | — | — |
| GPD1 deletion | GPD1 deletion shortens replicative lifespan by 25% and prevents lifespan extension by high osmolarity [12391171]. | Yeast | +25 | — | — |
| HAP5 deletion | Deletion of HAP5 shortens replicative lifespan by approximately 40%. This is not a premature aging phenotype as "old" HAP5 cells do not become premature sterile or exhibit other biomarkers of yeast aging [9271578]. HAP5 null mutants are unable to grow on a non-fermentable carbon source [7828851]. | Yeast | -40 | — | — |
| HDA1 deletion | Deletion of HDA1 has no effect on longevity under AL, but acts synergistically with 0.1% glucose restriction to increase replicative lifespan [12213553]. Deletion of HDA1 leads to a slightly increased chronological lifespan [19801973]. Deletion of HDA1 has no effect on the wild-type lifespan in the short-lifespan of YSK771 strain, but suppresses the short-lifespan of SIR3 mutants [10512855]. Null mutation results in increased telomeric silencing and increased histone acetylation [8962081]. | Yeast | — | — | — |
| YKU70 deletion | Deletion fo YKU70 shortens lifespan, but does not accelerate the normal aging process [10521401]. YKU70 null mutants are defective for non-homologous end-joining [8754818] and for telomeric silencing [9635192]. | Yeast | — | — | — |
| YKU80 deletion | Deletion of YKU80 shortens replicative lifespan, but does not accelerate the normal aging process [10521401]. YKU80 null mutant is defective for non-homologous end-joining [8754818] and for telomere silincing [9501103; 9635192] | Yeast | — | — | — |
| SRS2 deletion | Deletion of SRS2 shortens mean replicative lifespan by 50% [11290710]. Overexpression of SGS1 increases maximum, but not mean lifespan of SRS2 mutants [11861900]. Deletion of SRS2 is synthetical lethal in combination with deletion of SGS1 [11290710]. | Yeast | -50 | — | — |
| HSC82 deletion | Deletion of HSC82 has no effect on replicative lifespan, but shortens chronological lifespan [11361336]. | Yeast | — | — | — |
| HSP104 deletion | Deletion of HSP104 leads to a 14% [9851879] to 40% [17908928] reduction in mean replicative lifespan, therfore it is required for required for longevity. Exposure of cells to transient sub-lethal heat-stress extends mean lifespan by 12% while decreasing maximum lifespan by 14%. This effect does not occur in an HSP104 null mutant [9851879]. HSP104 null mutant is viable but displays reduced high temperature survival [8643570]. | Yeast | -14 to -40 | — | — |
| LAC1 deletion | Deletion of LAC1 the homolog of LAG1 [9872981] has no effect on replicative lifespan in strain W303R and PSY316 [N. Bishop, G. Liszt, and L. Guarente, unpublished]. LAC1 null mutant has no obvious growth defect [10198056], but is synthetically lethal with LAG1 mutation [9872981]. | Yeast | — | — | — |
| LAG1 deletion | A gene deletion of LAG1 in haploid cells results in a pronounced increase (approximately 50%) in mean and in maximum replicative lifespan in the YPHDF-1A strain [8195187], but has no significant effect on lifespan in stains W303R or PSY316 (N. Bishop, G.Liszt, and L. Guarente, unpublished]. The LAG1 transcribed is preferentially expressed in young cells. LAG1 null mutant is viable and has no obvious phenotypes but shows delayed ER to Golgi transport when combined with DGT1 mutation [10198056] and is synthetical lethal with LAC1 deletion. | Yeast | +50 | — | +50 |
| LAG2 deletion | Deletion of LAG2 in haploid SP1 strain does not affect growth, but results in a 50% decrease in the mean and maximum replicative lifespan [8760941]. | Yeast | -50 | — | -50 |
| Mating type heterozygosity | Mating type heterozygosity results in an approximately 20% mean replicative lifespan reduction, which occurs in both haploid and diploid cells (W303R) [10521401] and is likely due to increased homologous recombination [8454201] and rDNA circle formation [10521401]. | Yeast | -20 | — | — |
| MSN2 MSN4 double mutation | Deletion of MSN2 and MSN4 extends replicative lifespan and is further extended by cyr1::mTn [14741356]. Deletion of MSN2 and MSN4 does not significantly decrease chronological lifespan under AL, but attenuates chronological lifespan extension by water starvation and 0.5% glucose restriction [18225956] as well as cancels out lifespan extension of cyr1::mTn [14741356] and decreases chronological lifespan extension of ras2 deletion mutant [12586694]. Simulatnous deletion of MSN2 and MSN4 has no effect on chronological lifespan, but prevents lifespan extension by RAS2 deletion [12586694]. msn2 msn4 has no effect on replicative lifespan in PSY316, and does not prevent lifespan extension by DR [11000115] or by high osmolarity [12391171]. | Yeast | — | — | — |
| NCA3 deletion | Disruption in NCA3 shortens mean (87% of normal), nut not maximum replicative lifespan without causing any other gross changes in cell cycle parameters of growth characteristics [8810036].
In combination with an NCA2 disruption, NCA3 disruption causes a cryosensitive phenotype on non-fermentable carbon sources due to a defect in the F1-F0 ATP synthetase due to misbalancing of alternate spliceforms of mitochondrial mRNA encoding subunits 6 and 8 of the synthase [7586026]. | Yeast | -87 | — | — |
| DNM1 deletion | Deletion of DNM1 extends significantly mean and maximum lifespan by 49 and 111% in FY10 strain and by 15 and 12% in BY4741 strain [17173038]. | Yeast | +15 to +49 | — | +12 to +111 |
| FIS1 deletion | Deletion of FIS1 prolongs significantly mean and maximum lifespan by 13 and 29% as well as improves the fitness of old mother cells (in BY4741) [17173038]. | Yeast | +13 | — | +29 |
