    Description: We use a genome-wide association of 1 million parental lifespans of genotyped subjects and data on mortality risk factors to validate previously unreplicated findings near CDKN2B-AS1, ATXN2/BRAP, FURIN/FES, ZW10, PSORS1C3, and 13q21.31, and identify and replicate novel findings near ABO, ZC3HC1, and IGF2R. We also validate previous findings near 5q33.3/EBF1 and FOXO3, whilst finding contradictory evidence at other loci. Gene set and cell-specific analyses show that expression in foetal brain cells and adult dorsolateral prefrontal cortex is enriched for lifespan variation, as are gene pathways involving lipid proteins and homeostasis, vesicle-mediated transport, and synaptic function. Individual genetic variants that increase dementia, cardiovascular disease, and lung cancer – but not other cancers – explain the most variance. Resulting polygenic scores show a mean lifespan difference of around five years of life across the deciles.Editorial note: This article has been through an editorial process in which the authors decide how to respond to the issues raised during peer review. The Reviewing Editor's assessment is that all the issues have been addressed (see decision letter).

    Notes: Abstract We have used electrophoretic variants of glutamate-pyruvate transaminase (GPT, E.C. 2.6.1.2) in Drosophila melanogaster to genetically map the structural gene to position 42.6 on the X chromosome. By pseudodominance tests over several deficiencies we have localized it cytogenetically to the interval 11Fl-2 to 12Al-2. The sedimentation constant (s 20,w) of the native enzyme was determined in sucrose density gradients to be 5.9 and the native molecular weight approximately 87,000. The similarity in physical properties to mammalian enzymes suggests that the enzyme may also be dimeric in D. melanogaster.

    Notes: Abstract Genetic variation at three dipeptidase loci (Dip-A, Dip-B, and Dip-C) in Drosophila simulans was analyzed by starch gel electrophoresis. Dip-A was found to be polymorphic in four populations, while Dip-B and Dip-C were found to be polymorphic in one. The numbers of different alleles found at each respective locus were: Dip-A, two; Dip-B, two; and Dip-C, three. Dip-A was genetically mapped at 57.9 on the second chromosome, and Dip-B and Dip-C at 80.9 and 87.9 on the third chromosome, respectively. Neither Dip-B nor Dip-C has been mapped in D. melanogaster because both loci are apparently monomorphic. Their map positions in D. simulans with respect to flanking markers whose homologous genes have been cytogenetically localized in D. melanogaster suggested that they might be mapped cytogenetically by using available deficiencies in D. melanogaster. Accordingly, by the construction of interspecific hybrids which carried deficiencies of melanogaster and an allele of simulans with a mobility different from that of the fixed melanogaster allele, Dip-B and Dip-C were localized between 87F12-14 and 88C1-3 and between 87B5-6 and 87B8-10, respectively, in the salivary gland chromosomes of D. melanogaster. The similarity between these two species is discussed on the basis of these findings.

    Notes: Abstract The genetic and cytogenetic locations of the structural gene (Men) for malic enzyme have been determined. Men maps genetically between kar and ry at 51.73±0.02. Cytogenetically, Men probably lies in the proximal edge of 87D1,2, based on the results of mapping utilizing a number of deficiencies with breakpoints in that region. A number of null alleles have been recovered; heterozygotes for these nulls and a Men deficiency are both viable and fertile. These findings are related to the one band, one functional unit model of salivary gland chromosome structure.
