Genetics of Cellular Signalling
Cellular signalling pathways translate extracellular signals into intracellular responses, coordinating cell growth, survival, differentiation, and immune function. Genetic variants in signalling pathway components influence immune regulation, inflammatory responses, and cellular homeostasis.

What is Cellular Signalling?
Cells receive and process signals from their environment through receptor-mediated signalling cascades. Key pathways include PI3K-AKT-mTOR (growth and survival), RAS-MAPK (proliferation), WNT-beta-catenin (differentiation), and JAK-STAT (immune signalling). These pathways are interconnected and regulate gene expression, metabolism, and cellular behaviour. Genetic variants in signalling components can alter pathway activity, with implications for immune dysregulation, metabolic function, and susceptibility to chronic inflammatory conditions.
Biological pathways commonly discussed in relation to Cellular Signalling
Research into Cellular Signalling Pathways and Signal Transduction has highlighted several biological pathways that may be relevant. Genetic variants within these pathways may influence individual susceptibility, symptom severity, or the trajectory of the condition.
Mtor Signalling
mTOR (encoded by MTOR) integrates nutrient, energy, and growth signals to regulate protein synthesis, autophagy, and cellular metabolism. Variants in MTOR and PTEN affect cellular growth and metabolic signalling.
Wnt Signalling
WNT-beta-catenin signalling regulates cell differentiation and stem cell maintenance. CTNNB1 and related variants affect developmental and immune cell differentiation pathways.
Ras Mapk
RAS-MAPK signalling drives cell proliferation and differentiation downstream of growth factor receptors. This pathway is frequently mutated in cancer and may be subtly modulated by germline variants.
Pi3k Akt
PI3K-AKT signalling regulates cell survival, metabolism, and immune function downstream of cytokine and growth factor receptors. PTEN variants affect PI3K pathway restraint.

How personal DNA data may provide educational insights
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 relate to areas such as Cellular Signalling.
This is not a diagnostic service. Genetic variants do not determine whether you have Cellular Signalling, nor do they predict your clinical outcomes. 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. All results should be discussed with a qualified healthcare provider.

Frequently asked questions
Why is mTOR relevant to chronic illness?
mTOR integrates signals about nutrient availability, growth factors, and cellular energy to regulate protein synthesis, autophagy, and metabolism. In Long COVID, mTOR pathway dysregulation may contribute to impaired autophagy and cellular recycling, as well as metabolic dysfunction.
Which cellular signalling genes are most studied in immune contexts?
Key immune-relevant signalling genes include MTOR, PTEN, CTNNB1, KRAS, BRAF, MAP2K1, and AKT1. Additionally, overlap with JAK-STAT and NF-kB signalling creates interconnected regulatory networks.
What is PTEN and why does it matter?
PTEN is a phosphatase that negatively regulates the PI3K-AKT pathway. Germline loss-of-function PTEN variants cause PTEN hamartoma tumour syndrome. Partial loss-of-function variants may subtly enhance PI3K signalling in immune cells, potentially affecting immune activation thresholds.
How do signalling pathway variants differ from disease-causing mutations?
Germline signalling pathway variants studied in chronic illness typically have subtle, modulatory effects on pathway activity — unlike the strong driver mutations found in cancer. They may shift the biological balance rather than causing overt pathway dysfunction.
