The ZNF148 gene gives instructions for a protein that helps control when other genes are turned on or off, especially during early growth and brain development. The protein made by this gene helps your cells guide normal development in several organs. When a harmful variant disrupts this control, a person may have developmental delay, speech or learning difficulties, short stature, feeding problems, and sometimes differences in the brain, heart, kidneys, or facial features. The ZNF148 gene is mainly known in medical genetics rather than everyday health news.
What is a gene?
A gene is a stretch of DNA that holds information your cells use to make molecules or regulate processes in the body. Some genes provide the instructions for making proteins, the functional parts of cells. Others mainly help decide when, where, and how strongly certain processes take place. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
ZNF148Gene function
What if the gene works
The ZNF148 gene helps control when other genes turn on or off. This supports normal cell growth, development, and the steady function of tissues throughout the body.
Risk
What if the gene does not work
Pathogenic variants in the ZNF148 gene are linked to a neurodevelopmental condition with delayed development, speech problems, growth differences, and sometimes corpus callosum changes. Milder or more severe variants can influence which features appear and how marked they are.
Treatment
What does that mean for your treatment
For people with a pathogenic variant in the ZNF148 gene, no treatment or management approach based on this gene is currently established. The ZNF148 gene is being studied in cancer biology as a possible biomarker and drug target, but this has not led to routine treatment decisions.
Gene function
What if the gene works
The ZNF148 gene helps cells manage when other genes are turned on or off. Because of that, it supports steady cell growth, maturation, and normal development. Understanding how the ZNF148 gene helps control other genes makes its everyday role in the body easier to see.
The ZNF148 gene makes a protein that binds DNA near many genes. This helps cells adjust when those genes are read and how much of their instructions are used.
Its protein helps coordinate genes involved in cell growth, division, and maturation. This supports orderly day to day cell activity in many parts of the body.
ZNF148 also helps guide gene activity during early development. That steady control helps tissues follow normal growth patterns as the body forms.
What is a variant?
A genetic variant is a slight change in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many variants do not cause any noticeable effect and simply represent natural genetic variation. Sometimes, though, a variant can change how a gene works more significantly and may play a part in, or directly cause, a genetic condition.
Genetic variants
What if the gene does not work
Changes in the ZNF148 gene can make the cell produce too little ZNF148 protein or a shortened protein that does not interact with DNA normally. This helps explain how variants in the ZNF148 gene affect protein function: milder variants may leave some activity in place, while more disruptive variants can more strongly disturb gene control inside the cell. In people with conditions linked to the ZNF148 gene, that difference may shape how early features appear and how marked they are.
How variants are linked to conditions
Pathogenic variants in the ZNF148 gene cause a rare neurodevelopmental condition. Reported features include developmental delay or intellectual disability, short stature, feeding difficulties, and, in some children, differences in the band connecting the two sides of the brain. ZNF148 gene variants linked to developmental delay describe a confirmed genetic diagnosis, although the exact mix and severity of features can vary from person to person.
A variant is not necessarily a diagnosis
Genetic variants are a common and expected part of human biology. Most have no direct impact on health and simply reflect natural variation among people. For many genes, carrying a variant associated with a condition suggests a possible connection rather than a certain diagnosis, especially when several genes and environmental influences are involved. In some situations, however, one well-characterized variant in a particular gene is enough to confirm the 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 risks related to the ZNF148 gene. For many living with a ZNF148-related genetic change, the main driver is the variant itself rather than lifestyle or environmental factors, and a doctor or genetic counselor can help explain personal risk and follow-up care.
Inheritance of ZNF148 variants
ZNF148-related conditions are usually inherited in an autosomal dominant pattern, which means one altered copy of the ZNF148 gene can be enough to cause the condition. If a parent carries a disease-causing variant, each child has a 50% chance of inheriting it. In practice, many reported cases help explain how ZNF148 variants are inherited because they arise as a new (de novo) variant in the child, with neither parent carrying the same change. Both males and females can inherit and pass on ZNF148 variants.
What does my ZNF148 result mean for my family?
For ZNF148, the best-known related condition follows a dominant pattern, so a parent with the same disease-causing variant can pass it to a child. In many reported families, the variant happened new in the child rather than being inherited, so parents may not have it themselves. This means close relatives may have different chances of sharing the result depending on whether it was inherited or new in the family.
Genetic information
Genetic testing
How you find out about variants
ZNF148 genetic testing looks for changes in the ZNF148 gene using DNA from a blood sample or saliva sample. A lab reads the gene’s sequence, compares it with the usual sequence, and reports whether a variant is found, including whether it is known to explain a person’s features, is likely benign, or is still uncertain.
When should I consider getting a genetic test?
Genetic testing for the ZNF148 gene may be worth considering when a child has unexplained developmental delay, learning difficulties, poor growth, feeding problems, or certain differences seen on brain scans. It can also help if there is a family history of a ZNF148-related condition.
A genetic result is only one part of your health story
Genetic results can offer useful insight, yet how much they reveal depends on the condition and the kind of variant involved. Many other factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. In some conditions, especially those affected by many genes, genetic information provides context rather than certainty and is most useful when considered alongside other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, these results can also help put individual experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in DNA can change how the body breaks down a drug, moves it through the bloodstream, or responds to it at its target. This is common and can help explain why the same treatment works well for one person, works less well for another, or causes more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can shape the way medications affect them. It studies the relationship between genes and drugs to help explain why the same treatment can work differently from one person to another. With many medicines, genes can influence how strongly a drug works or how the body handles it. This information can support treatment decisions that are both better informed and more individualized.

Drugs influenced by the ZNF148 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how medicines are chosen or used, so questions about side effects, new symptoms, or changes to your treatment are best discussed with your doctor.
