Disease Profile

Naegeli syndrome

Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Age of onset






Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.


Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.


dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.


recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.


Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Naegeli syndrome belongs to a group of disorders known as ectodermal dysplasias. This condition is characterized by absent fingerprints, thickening of the palms and soles (palmoplantar keratoderma), decreased sweating (hypohidrosis), heat intolerance, patches of darker (hyperpigmented) skin, brittle nails, abnormally colored teeth, and early tooth loss. Naegeli syndrome is caused by mutations in the KRT14 gene and inherited in an autosomal dominant manner. While there is no cure for Naegeli syndrome, treatment is based on each individual's symptoms.[1][2][3]


This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

In most cases of Naegeli syndrome, a diagnosis is made based on the typical clinical features of this condition.[1] The diagnosis may be confirmed by genetic testing of the KRT14 gene.

Testing Resources

  • The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
  • Orphanet lists international laboratories offering diagnostic testing for this condition.


    Treatment for Naegeli syndrome is based on an individual's symptoms. Dry skin can be moisturized with creams. Exposure to heat should be limited. To avoid overheating, affected individuals should stay hydrated, wear appropriate clothing, and use wet dressings. Dental care is needed to treat cavities and tooth loss.[1][3]


    Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer.
