What is the rs3748082 variant?
rs3748082 is a SNP (single nucleotide polymorphism) in the CAMP (Cathelicidin Antimicrobial Peptide) gene. It belongs to the Innate Immunity category and is part of the Innate Immunity & Interferons biological cluster. CAMP encodes the precursor of LL-37, a cathelicidin antimicrobial peptide with broad-spectrum antimicrobial, antiviral, and immunomodulatory activities. LL-37 activates innate immune cells, promotes wound healing, and has anti-biofilm properties.
Biological role and pathway
This variant sits within the CAMP gene, which is involved in the antimicrobial defense pathway. Genes within the Innate Immunity & Interferons 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.
rs3748082 and Long COVID / ME-CFS research
LL-37 has antiviral activity against respiratory viruses and anti-inflammatory regulatory roles. Vitamin D strongly induces CAMP expression; variants in CAMP or its regulatory regions may affect mucosal immunity relevant to SARS-CoV-2 vulnerability and recovery.

Frequently asked questions
What is the rs3748082 variant in the CAMP gene?
rs3748082 is a single nucleotide polymorphism (SNP) located in the CAMP (Cathelicidin Antimicrobial Peptide) gene, which is involved in antimicrobial defense. CAMP encodes the precursor of LL-37, a cathelicidin antimicrobial peptide with broad-spectrum antimicrobial, antiviral, and immunomodulatory activities. LL-37 activates innate immune cells, promotes wound healing, and has anti-biofilm properties.
How may the rs3748082 variant relate to Long COVID or ME/CFS?
LL-37 has antiviral activity against respiratory viruses and anti-inflammatory regulatory roles. Vitamin D strongly induces CAMP expression; variants in CAMP or its regulatory regions may affect mucosal immunity relevant to SARS-CoV-2 vulnerability and recovery.
Can a consumer DNA test detect the rs3748082 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.
