The ZNF141 gene helps control when other genes switch on during early development, especially as the hands and feet are forming. This gene plays an important role in shaping the outer parts of the limbs. If it does not work as expected, some people are born with extra fingers or toes, usually on the outer side of the hand or foot.
What is a gene?
Genes are stretches of DNA that give your cells instructions for making molecules or directing activities in the body. Some genes provide the information needed to make proteins, the parts of cells that do much of the work. Other genes are used mainly to regulate when certain processes happen, where they happen, and how strongly they run. Together, genes affect how the body develops and works, and they can shape how you respond to food, stress, or medications. For a more detailed look at this topic, you can find more in the LearnHub.
Overview
ZNF141Gene function
What if the gene works
The ZNF141 gene helps control when other genes turn on and off. This supports early body development, including the growth and patterning of the hands and feet.
Risk
What if the gene does not work
Variants in the ZNF141 gene are linked to postaxial polydactyly, with extra fingers or toes on the outer side of the hands or feet. Milder to more severe variants can influence whether changes are small nubbins or more fully formed digits.
Treatment
What does that mean for your treatment
No ZNF141-specific treatment, management approach, or drug selection is currently established for pathogenic variants in the ZNF141 gene.
Conditions associated with ZNF141
Gene function
What if the gene works
Your cells use the ZNF141 gene to help manage which genes are active at different times. It makes a DNA binding protein that works like a switchboard, guiding normal patterns of gene use during growth and routine cell activity. This is especially important in early development, when cells need clear instructions.
The ZNF141 gene makes a protein that attaches to DNA and helps control when other genes are used. This timing helps cells follow the right instructions as they grow and take on specific roles.
Its protein has small finger-like sections that recognize specific DNA sequences. This lets cells use selected parts of their genetic instructions instead of turning on every gene at once.
During early development, the ZNF141 gene helps coordinate patterns of gene activity. This supports orderly tissue formation as cells respond to growth signals and build the body plan.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body reacts to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. Sometimes, though, a variant changes how a gene works more significantly and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ZNF141 gene can change the protein’s shape, stability, or ability to attach to DNA, which can disrupt how cells switch other genes on and off during limb development. Milder variants may leave some activity in place, while more severe variants can greatly reduce or stop this DNA binding. These ZNF141 gene variant effects on limb development can influence how strongly the gene change shows up, including how noticeable extra or fused digits may be.
How variants are linked to conditions
Pathogenic variants in the ZNF141 gene cause a rare inherited limb condition called postaxial polydactyly type A, the main finding described in reports on ZNF141 gene variants linked to conditions. People with this diagnosis are born with extra fingers or toes on the outer side of the hand or foot, often with formed bones and joints. When two disease-causing variants are present, finding them can confirm the genetic diagnosis in an affected person.
A variant is not necessarily a diagnosis
Gene variants are a routine part of human biology and are common across the general population. Most do not have a direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a certain diagnosis, especially when more than one gene and environmental factors are involved. In some situations, though, a single well characterized variant in a particular gene can be 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 ZNF141 gene. For families with a disease-causing change in ZNF141, risk is mostly shaped by whether that genetic change is inherited, rather than by lifestyle or everyday exposures.
Inheritance of ZNF141 variants
ZNF141-related conditions are inherited in an autosomal recessive pattern. This means a child usually needs to inherit two altered copies of the ZNF141 gene, one from each parent, to be affected. Parents who each carry one variant are often unaffected themselves, and with each pregnancy there is a 25% chance of having an affected child, a 50% chance of having a child who is a carrier, and a 25% chance of having a child without the familial variant. In families asking about the ZNF141 gene inheritance pattern, this also means carriers can pass the variant to sons and daughters equally.
What does my ZNF141 result mean for my family?
Changes in the ZNF141 gene are linked to a rare inherited hand or foot difference that usually follows a recessive pattern in families. This often means parents can carry the gene change without having any obvious signs, while brothers and sisters may also be affected or be carriers. Other relatives may carry the same change too, especially on the same side of the family.
Genetic information
Genetic testing
How you find out about variants
A blood, saliva, or cheek swab sample can be used for genetic testing for ZNF141 variants. The lab reads the DNA in the ZNF141 gene and looks for changes that may help explain an inherited pattern, often using a multigene panel or exome test. Results can show a benign variant, a variant linked to the condition, or an uncertain result.
When should I consider getting a genetic test?
Consider testing for the ZNF141 gene if you or your child has extra fingers or toes, especially if this runs in the family or affects more than one relative. A result can help show whether ZNF141 is the cause and can clarify the chance of it happening again in future children.
A genetic result is only one part of your health story
Genetic findings can be very informative, yet how much they reveal varies depending on the condition and the type of variant identified. Over time, many factors influence how the body functions, including lifestyle, environment, age, and medical history. 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 can provide a clear answer. In areas such as 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. Two people can take the same treatment, yet one may get the intended benefit while another may notice less effect or be more sensitive to side effects, partly because their bodies break down, transport, or respond to the drug differently. These differences are common and are one reason medication response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect response to medicines. It looks at relationships between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body handles it. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the ZNF141 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work or what side effects they may cause. Questions about your medicines, side effects, or changes in your health are best discussed with your doctor or pharmacist.
