The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
|Signs and Symptoms||Approximate number of patients (when available)|
|Neoplasm of the breast||50%|
|Neoplasm of the colon||50%|
|Neoplasm of the pancreas||50%|
|Abnormality of the nail||7.5%|
|Abnormality of the skin||-|
|Autosomal dominant inheritance||-|
Autosomal dominant inheritance is when only one mutated copy of a disease-causing gene in each cell is sufficient for a person to be affected. An autosomal dominant condition may occur for the first time in an affected individual due to a new mutation, or may be inherited from an affected parent. When a person with an autosomal dominant disorder has a child, there is a 50% chance that his/her child will inherit the condition.
Keratosis palmoplantaris papulosa shows “age dependent penetrance” and possibly “variable penetrance” as well. Age dependant penetrance means that the older the person is, the more likely they are to develop symptoms if they have inherited the disease causing gene mutation.
Variable penetrance means that not everyone who inherits the gene mutation that causes keratosis palmoplantaris papulosa develops the signs and symptoms of the condition. However this person would still be at risk of passing the disease-causing mutation to their offspring.
Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Nonprofit support and advocacy groups bring together patients, families, medical professionals, and researchers. These groups often raise awareness, provide support, and develop patient-centered information. Many are the driving force behind research for better treatments and possible cures. They can direct people to research, resources, and services. Many groups also have experts who serve as medical advisors. Visit their website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
Living with a genetic or rare disease can impact the daily lives of patients and families. These resources can help families navigate various aspects of living with a rare disease.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.

I have keratosis palmoplantaris papulosa and so did my mother. Lately I have been burning off the little nodules using liquid nitrogen. Painful but it does work. Although the condition is genetic, I have been suspicious that there may be a possible exogenous trigger like a virus. Has any research been done to check whether there is any viral involvement?

My father has Buschke Fischer keratoderma palmo-plantaris. Is there any treatment for this condition? See answer
