KAT6A Gene

What is the KAT6A gene?

KAT6A encodes lysine acetyltransferase 6a, a protein involved in histone H3K23 acetylation / chromatin remodeling. It belongs to the Epigenetics category and is part of the Methylation & Neurotransmitters biological cluster. KAT6A encodes MOZ, a histone acetyltransferase that acetylates H3K23 and regulates developmental gene expression.

Biological role and pathway

KAT6A is involved in the histone H3K23 acetylation / chromatin remodeling pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Methylation & Neurotransmitters 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.

Known genetic variants

The following variants (SNPs) in the KAT6A gene have been studied in relation to epigenetics and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

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 KAT6A and related genes in the methylation & neurotransmitters pathway.

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.
