Naegeli-Franceschetti-Jadassohn syndrome (NFJS), also known as dermatopathia pigmentosa reticularis, is a rare inherited skin disorder characterized by abnormalities in the the sweat glands and teeth. NFJS is one of a group of disorders known as ectodermal dysplasias, which affect tissues derived from the outermost layer of the embryo (the ectoderm). The main features of NFJS include reticulate hyperpigmentation (dark, reticular patches) on the skin, absence or reduction of sweat glands, and enamel defects in the teeth.

This condition is inherited in an autosomal dominant manner, which means that a mutation in one copy of the gene that causes NFJS is sufficient to cause the disorder. Some affected individuals have an affected parent, while others have a new mutation in the gene. There have been 30 reported cases of NFJS in the scientific literature, and additional genetic testing is needed to learn more about the genes and mutations associated with this condition.

Currently, there is no cure for NFJS, but with proper care and support, affected individuals can manage the symptoms associated with the disorder. The Ectodermal Dysplasia Advocacy and Awareness Network (EDANN) offers resources and support for individuals and families affected by NFJS. If you or a loved one has been diagnosed with NFJS, it is important to reach out to the EDANN for information, advocacy, and support.

Frequency

The Naegeli-Franceschetti-Jadassohn syndrome (NFJS), also known as dermatopathia pigmentosa reticularis, is a rare genetic condition characterized by reticulate hyperpigmentation, hypohidrosis (decreased ability to sweat), and tooth abnormalities. The exact frequency of this condition is not well-established, but it is considered to be a rare disease.

Due to its rarity, NFJS may often go undiagnosed or misdiagnosed. Testing for NFJS can be done through genetic testing to identify mutations in the KRT14 gene, which is associated with this condition. It is important to note that not all individuals with NFJS will have mutations in this gene, so additional testing may be required.

Resources and support for patients with NFJS and other rare genetic diseases can be found through advocacy organizations, such as the NFJS Center, which provides information, support, and resources for patients and their families. These organizations often provide educational materials, support groups, and access to scientific articles and research.

The inheritance pattern of NFJS is autosomal dominant, meaning that an affected individual has a 50% chance of passing the condition on to each of their children. However, in some cases, NFJS may occur sporadically, without a family history of the condition.

For more information about NFJS, its causes, and associated genes, the Online Mendelian Inheritance in Man (OMIM) database is a valuable resource. OMIM provides a catalog of genes, genetic disorders, and related clinical features. It also references scientific articles and research on NFJS and other related conditions.

PubMed contains a wealth of information on NFJS, including studies on the genetic mutations involved, other possible causative genes, apoptosis in NFJS tissues, and more.

Causes

The Naegeli-Franceschetti-Jadassohn syndrome (NFJS), also known as dermatopathia pigmentosa reticularis, is a rare genetic condition. It is caused by mutations in the gene named “KRT14” or “KRT16”.

These mutations affect the production and structure of keratins, which are proteins that provide support and strength to the skin, nails, and other tissues. In NFJS, the mutations in the KRT14 or KRT16 genes result in abnormalities in the skin’s pigment-producing cells, leading to the reticulate pattern of pigmentation seen in affected individuals.

NFJS has an autosomal dominant inheritance pattern, which means that a mutation in one copy of the KRT14 or KRT16 gene is sufficient to cause the condition. In some cases, the condition occurs sporadically, meaning that there is no family history of the condition. The exact frequency of NFJS is not known, but it is considered to be a rare disease.

Scientific research on NFJS and dermatopathia pigmentosa reticularis is ongoing, and there are several articles available on PubMed and other scientific databases that provide more information about the genetic mutations associated with these conditions. Gene testing can be done to confirm a diagnosis of NFJS.

For more information about NFJS, along with advocacy and support resources, the Online Mendelian Inheritance in Man (OMIM) database and patient advocacy organizations can be valuable sources of information.
