DGKI helps cells manage fat-based chemical signals that control communication, growth, and responses to stimulation. This gene plays an important role in keeping those signals balanced, especially in nerve cells; if it does not work well, signaling may become less controlled and could influence brain function and related health risks. Some DGKI variants have been studied in psychiatric and neurological research, but their effects can vary.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells use to make molecules or direct processes in the body. Some genes hold the directions for producing proteins, which are the working parts of cells. Others mainly regulate when certain processes happen, where they occur, and how strongly they run. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, or medications.

Overview
DGKIGene function
What if the gene works
The DGKI gene helps control cell signaling by converting one fat messenger, diacylglycerol, into another, phosphatidic acid. This supports how cells respond to signals, especially in the brain.
Risk
What if the gene does not work
Changes in the DGKI gene can range from milder to more severe variants, which may reduce how well cells convert diacylglycerol, a signaling fat, into phosphatidic acid. This can disrupt signaling pathways that help nerve cells communicate and respond normally.
Treatment
What does that mean for your treatment
No DGKI-specific treatment or management approach is currently established, so a pathogenic or loss-of-function variant in the DGKI gene does not currently guide drug choice in routine care. Treatment decisions are based on the person’s diagnosed condition and clinical needs rather than DGKI status.
Gene function
What if the gene works
Cell messages need to start, peak, and settle at the right time. The DGKI gene helps manage that timing by changing one fat based signal into another that cells can use differently. This keeps everyday communication inside cells more balanced, especially in pathways linked to the cell membrane.
The DGKI gene makes an enzyme that changes diacylglycerol, a fat based cell messenger, into phosphatidic acid, another signaling fat. This switch helps move a signal from one stage to the next.
By lowering diacylglycerol levels, this gene helps keep some cell messages from staying on too long. It also creates phosphatidic acid, which supports a different set of signals, so communication stays better tuned.
Much of this work happens at cell membranes, where many signals begin. This is part of what the DGKI gene does in normal cell signaling.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These differences are common and help shape normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many have no noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can change the function of a gene more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the DGKI gene can lower how much usable protein a cell makes, weaken the enzyme's activity, or make the protein less stable in the right part of the cell. This helps explain how variants in the DGKI gene affect cell signaling, because the balance of key lipid messengers can shift when the protein works less well. Some variants have a mild effect, while more severe loss-of-function variants can leave little or no working protein.
How variants are linked to conditions
Variants in the DGKI gene do not yet have a broadly confirmed link to a specific health condition, so current evidence on DGKI gene variants linked to conditions remains limited and may change as research develops. Anyone with a confirmed finding in the DGKI gene should rely on guidance from their doctor or genetic counselor rather than general information alone.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal part of human biology. Most do not have a direct effect on health and simply reflect natural human diversity. With many genes, having a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when several genes and environmental factors contribute. In some situations, though, one well characterized variant in a particular gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the DGKI gene. If a DGKI change is found on testing, its meaning often depends on the exact change and the rest of a person’s health and family history.
Inheritance of DGKI variants
For people trying to understand how variants of the DGKI gene are inherited, there is not yet a broadly confirmed inheritance pattern tied to one specific DGKI related condition. Research on this gene is still developing, so DGKI is not currently described as having a well established autosomal dominant, autosomal recessive, or X linked inheritance pattern for a defined genetic condition. The DGKI gene is located on chromosome 7, which is an autosome, so each person inherits one copy from each parent.
What does my DGKI result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the DGKI gene, though this can change as research grows. If you have a specific DGKI result and want to understand what it could mean for close relatives, a doctor or genetic counselor can help interpret it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the DGKI gene, labs use genetic testing on a blood or saliva sample. In practice, DGKI genetic testing works by reading the gene's DNA code and comparing it with the usual sequence to spot a variant. Results may show no variant, a known variant, or a variant whose meaning is still being clarified.
When should I consider getting a genetic test?
There isn't yet a broadly established medical reason to get genetic testing just for the DGKI gene. Testing decisions are usually based on your own health history and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals depends on the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is most helpful when considered alongside other parts of care. In other situations, a genetic result may give a clear answer. In areas such as medication response, genetic results can help put personal experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Some people break down a drug more quickly, while others process it more slowly, which can change how much of the medicine reaches the body and for how long. This common variation can influence how well a treatment works or how likely someone is to notice side effects. Medication response is also shaped by other factors, including age, liver and kidney function, and other medicines a person takes.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect a person’s response to medications. It studies the relationship between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence either how strongly a drug works or how the body processes it. This information can support more informed, individualized treatment decisions.

Drugs influenced by the DGKI gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are chosen or used, so any questions about treatment, side effects, or medication changes are best discussed with your doctor.
