HNF1A Gene

What is the HNF1A gene?

HNF1A encodes hepatocyte nuclear factor 1-alpha, a protein involved in MODY3 / liver and pancreas gene regulation. It belongs to the Metabolic category and is part of the Metabolic Regulation biological cluster. HNF1A encodes a transcription factor critical for liver, kidney, and pancreatic beta cell function; mutations cause MODY3.

Biological role and pathway

HNF1A is involved in the MODY3 / liver and pancreas gene regulation pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Metabolic Regulation 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 HNF1A gene have been studied in relation to metabolic and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs1169288— HNF1A variant
• rs2244608— HNF1A variant

Conditions studied in relation to HNF1A

Research into HNF1A variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that HNF1A causes or treats any condition.

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 HNF1A and related genes in the metabolic regulation 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.
