Healthcare professional explaining the longevity-aging pathway in genetic testing — PlexusDx Precision Peptide Genetic Test

What Is the Longevity-Aging Pathway in Genetic Testing?

The Longevity-Aging pathway in the Precision Peptide Genetic Test delivers 17 insights organized across five functional clusters — antioxidant defense, NAD+ homeostasis, methylation, longevity transcription factors, and structural aging biology. Part of 14 pathways, 49 peptides, and 150+ genetic insights, these 17 variants map biological aging as a connected system, not a list of isolated risk genes.

APOE Genotypes and Healthy Aging: A Deep Dive

APOE comes in three allele variants — e2, e3, and e4 — that produce meaningfully different cardiovascular and cognitive aging trajectories. It is the most studied aging-related gene in human genetics. The Precision Peptide Genetic Test analyzes APOE as part of 17 Longevity & Aging insights within a panel spanning 14 pathways, 49 peptides, and 150+ genetic insights.
