Bioinformatics and genomics services play a critical role in Alzheimer's disease research by providing the infrastructure for genetic analysis, biomarker discovery, and mechanistic studies. This page catalogs companies offering sequencing, single-cell genomics, multi-omics integration, and bioinformatics services relevant to AD research. The companies listed here provide the technological backbone for major discoveries in AD genetics, from the identification of [APOE](/genes/apoe) as the primary genetic risk factor to recent breakthroughs in understanding microglial biology through [TREM2](/genes/trem2) risk variants.
Major Service Providers
Illumina
- Headquarters: San Diego, CA, USA
- Website: [illumina.com](https://www.illumina.com)
- Services: Next-generation sequencing (NGS), whole genome sequencing, exome sequencing, arrays
- AD Relevance: Illumina platforms are extensively used in AD genetics consortia, including the Alzheimer's Disease Neuroimaging Initiative (ADNI) and the International Alzheimer's Disease Genetics Consortium. Their NovaSeq and HiSeq systems enable large-scale GWAS and whole genome sequencing studies identifying AD risk genes including [APOE](/genes/apoe), [TREM2](/genes/trem2), and [CLU](/genes/clu).
Technology Platform Details:The Illumina NovaSeq 6000 delivers highest-throughput sequencing at $2-5 per Gb, making it cost-effective for large AD cohort studies. The system has been used to sequence over 100,000 AD and control genomes globally, identifying rare coding variants in genes involved in [microglial immune response](/mechanisms/microglial-activation-pathway), [lysosomal function](/mechanisms/lysosomal-autophagy-pathway), and [protein homeostasis](/mechanisms/proteostasis-pathway).
The Illumina Infinium MethylationEPIC array provides genome-wide DNA methylation profiling, identifying epigenetic changes in AD brain tissue. Studies using this platform have documented hypermethylation at [TREM2](/genes/trem2) promoter regions in AD cases, correlating with reduced TREM2 expression and enhanced [neuroinflammation](/mechanisms/neuroinflammation-pathway).
Thermo Fisher Scientific
- Headquarters: Waltham, MA, USA
- Website: [thermofisher.com](https://www.thermofisher.com)
- Services: Sequencing services, gene expression analysis, proteomics, reagents
- AD Relevance: Provides the Ion Torrent platform for targeted sequencing panels used in AD research. Their TaqMan assays are the gold standard for SNP genotyping in AD genetics studies.
Technology Platform Details:The Ion GeneChef S5 XL system enables rapid targeted sequencing of AD genetic panels within 24 hours. Commercial panels include genes involved in [amyloid processing](/mechanisms/amyloidogenesis-pathway) (APP, PSEN1, PSEN2), [tau phosphorylation](/mechanisms/tau-phosphorylation-pathway) (MAPT), and [autophagy-lysosomal](/mechanisms/lysosomal-autophagy-pathway) pathways (GRN, CTSH, CTSS).
TaqMan genotyping assays have been used to confirm [APOE](/genes/apoe) genotype in over 500,000 AD research subjects worldwide. The ε4 allele remains the strongest genetic risk factor for late-onset AD, increasing risk 3-4 fold in heterozygotes and 10-15 fold in homozygotes.

- APOE region: Long-read sequencing has identified novel [APOE](/genes/apoe) isoforms and structural variants that influence AD risk through altered lipid binding properties
- TREM2: HiFi sequencing resolves rare missense variants in [TREM2](/genes/trem2) that impair microglial phagocytosis and contribute to [amyloid accumulation](/mechanisms/amyloid-plaque-formation)
