rs5848
Variant in the GRN gene (Granulin Precursor (Progranulin))
rs5848 is a single nucleotide polymorphism (SNP) in the GRN gene, involved in microglial PGRN / neuroinflammation / FTLD. Variants at this position have been studied in relation to immune function, metabolism, and chronic illness.

What is the rs5848 variant?
rs5848 is a SNP (single nucleotide polymorphism) in the GRN (Granulin Precursor (Progranulin)) gene. It belongs to the Neurological category and is part of the Neurological & Cognitive Function biological cluster. GRN encodes progranulin (PGRN), a neurotrophic and anti-inflammatory factor secreted by neurons and microglia; haploinsufficiency causes frontotemporal dementia.
Biological role and pathway
This variant sits within the GRN gene, which is involved in the microglial PGRN / neuroinflammation / FTLD pathway. Genes within the Neurological & Cognitive Function cluster work together to maintain balanced function across interconnected biological systems.
Variants in genes within this pathway may influence an individual's predisposition to altered function — particularly under conditions of physiological stress such as viral infection or prolonged illness.
rs5848 and Long COVID / ME-CFS research
Progranulin has strong anti-inflammatory and neuroprotective properties; GRN variants affecting progranulin levels may influence microglial inflammatory responses and neurological outcomes in Long COVID.

Genetic insights from DNA data
Consumer DNA files from 23andMe, AncestryDNA, and MyHeritage contain raw SNP data. When you upload your file to ChronicDNA, the analysis engine checks your genotype against a curated panel of 80+ genes selected for their relevance to Long COVID, ME/CFS, and connected biological pathways - some of which may include GRN and the rs5848 variant.
The report is educational - it explains which variants you carry, what the research says about them, and how they fit into the biological pathways most relevant to chronic illness. Results are presented in plain English with appropriate scientific context, no medical jargon, no scare tactics. All results should be discussed with a qualified healthcare provider.

The following variants in GRN are also studied in relation to chronic illness and may be analysed together for a more complete picture.
Frequently asked questions
What is the rs5848 variant in the GRN gene?
rs5848 is a single nucleotide polymorphism (SNP) located in the GRN (Granulin Precursor (Progranulin)) gene, which is involved in microglial PGRN / neuroinflammation / FTLD. GRN encodes progranulin (PGRN), a neurotrophic and anti-inflammatory factor secreted by neurons and microglia; haploinsufficiency causes frontotemporal dementia.
How may the rs5848 variant relate to Long COVID or ME/CFS?
Progranulin has strong anti-inflammatory and neuroprotective properties; GRN variants affecting progranulin levels may influence microglial inflammatory responses and neurological outcomes in Long COVID.
Can a consumer DNA test detect the rs5848 variant?
Many consumer DNA tests such as 23andMe, AncestryDNA, and MyHeritage genotype common SNPs. ChronicDNA analyses your raw DNA file and reports on variants studied in relation to chronic illness, immune function, and metabolism. This is not a diagnostic service — results are informational and educational only.
