MYD88 Gene
MYD88 Innate Immune Signal Transduction Adaptor (MYD88) is a gene involved in TLR signaling that has been studied in relation to immune function, metabolism, and chronic illness. Variants in MYD88 may influence how the body responds to infection, inflammation, and long-term recovery.

What is the MYD88 gene?
MYD88 encodes myd88 innate immune signal transduction adaptor, a protein involved in TLR signaling. It belongs to the Innate Immunity category and is part of the Innate Immunity & Interferons biological cluster. MyD88 is the universal adaptor protein for most Toll-like receptors and IL-1 family receptors. It recruits IRAK kinases to activate NF-κB and MAPK pathways. Inherited MyD88 deficiency causes susceptibility to invasive pneumococcal disease.
Biological role and pathway
MYD88 is involved in the TLR signaling pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. 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 in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.
MYD88 and Long COVID / ME-CFS research
MYD88 variants affecting TLR-IL1R signaling may influence COVID-19 susceptibility and the sustained innate immune activation driving Long COVID. Gain-of-function MYD88 mutations are known oncogenic drivers, while loss-of-function increases infection susceptibility.

Frequently asked questions
What is the MYD88 gene and what does it do?
MYD88 (MYD88 Innate Immune Signal Transduction Adaptor) is involved in TLR signaling. MyD88 is the universal adaptor protein for most Toll-like receptors and IL-1 family receptors. It recruits IRAK kinases to activate NF-κB and MAPK pathways. Inherited MyD88 deficiency causes susceptibility to invasive pneumococcal disease.
How may MYD88 gene variants relate to Long COVID or ME/CFS?
MYD88 variants affecting TLR-IL1R signaling may influence COVID-19 susceptibility and the sustained innate immune activation driving Long COVID. Gain-of-function MYD88 mutations are known oncogenic drivers, while loss-of-function increases infection susceptibility.
