  • Longitudinal change in memory performance as a strong endophenotype for Alzheimer's disease - Unknown journal (n.d.) · Unknown authors · PubMed 37985223

    ABSTRACT: Abstract INTRODUCTION Although large‐scale genome‐wide association studies (GWAS) have been conducted on AD, few have been conducted on continuous measures of memory performance and memory decline. METHODS We conducted a cross‐ancestry GWAS on memory performance (in 27,633 participants) and memory decline (in 22,365 participants; 129,201 observations) by leveraging harmonized cognitive data from four aging cohorts. RESULTS We found high heritability for two ancestry backgrounds. Further, we found a novel ancestry locus for memory decline on chromosome 4 (rs6848524) and three loci in the non‐Hispanic Black ancestry group for memory performance on chromosomes 2 (rs111471504), 7 (rs4142249), and 15 (rs74381744). In our gene‐level analysis, we found novel genes for memory d

  • A genome-wide search for pleiotropy in more than 100,000 harmonized longitudinal cognitive domain scores - Unknown journal (n.d.) · Unknown authors · PubMed 37349795

    ABSTRACT: Background More than 75 common variant loci account for only a portion of the heritability for Alzheimer's disease (AD). A more complete understanding of the genetic basis of AD can be deduced by exploring associations with AD-related endophenotypes. Methods We conducted genome-wide scans for cognitive domain performance using harmonized and co-calibrated scores derived by confirmatory factor analyses for executive function, language, and memory. We analyzed 103,796 longitudinal observations from 23,066 members of community-based (FHS, ACT, and ROSMAP) and clinic-based (ADRCs and ADNI) cohorts using generalized linear mixed models including terms for SNP, age, SNP × age interaction, sex, education, and five ancestry principal components. Significance was determined based o

  • Multi‐ancestry meta‐analysis identifies genetic modifiers of age‐at‐onset of Alzheimer's disease at known and novel loci - Unknown journal (n.d.) · Unknown authors · PubMed 40883957

    ABSTRACT: Abstract INTRODUCTION Much of Alzheimer's disease (AD) risk is explained by age, apolipoprotein E (APOE) genotype, and sex. We sought to identify genetic modifiers of age at onset (AAO) of AD while probing the influence of sex and APOE among those with diverse ancestry. METHODS We performed genome‐wide association studies (GWASs) of AAO in two diverse samples followed by meta‐analysis, contrasting results with and without adjustment for sex and APOE. Genome‐wide significance was set to p < 5×10−8. RESULTS GWASs adjusting for sex, APOE, population structure, and relatedness revealed 17 significant loci including independent associations at AD risk loci and four novel signals. APOE adjustment influenced GWAS effect sizes across the genome while sex adjustment had minimal
