Familial pityriasis rubra pilaris (PRP) is a rare genetic condition that affects multiple members of a family. PRP is a skin disorder characterized by the development of thick, scaly patches on the palms of the hands and/or the soles of the feet. These patches can also appear on other areas of the body, such as the elbows, knees, and scalp.

The exact cause of familial PRP is not yet known. However, research has shown that the condition is inherited in an autosomal dominant manner, meaning that a child has a 50% chance of inheriting the faulty gene from an affected parent. Several genes have been identified as possibly causing familial PRP, with more research needed to fully understand their role in the development of the condition.

Although there is currently no cure for familial PRP, there are treatments available to help manage the symptoms. These include topical and oral medications, as well as phototherapy. It is important for patients with familial PRP to work closely with their healthcare team to find the most effective treatment plan for their individual needs.

For more information and support for patients and families affected by familial PRP, there are several advocacy organizations and additional resources available. The PRP Alliance is a non-profit organization that provides information and support for individuals with PRP and their families. The National Organization for Rare Disorders (NORD) also offers resources and information on PRP, including a patient registry and referral program.

In conclusion, familial pityriasis rubra pilaris is a rare genetic condition that causes thick, scaly patches on the skin. While the exact cause is still being researched, the condition is inherited in an autosomal dominant manner. Treatment options are available to manage the symptoms, and support and resources are available for patients and families affected by this condition.

Frequency

Familial pityriasis rubra pilaris (PRP) is a rare condition, with a frequency estimated to be between 0.5 and 1 in 1 million people. It is characterized by keratoderma, erythema, and follicular plugging. The exact frequency of familial PRP is difficult to determine due to the rarity of the condition and the lack of genetic testing and registries.

Once you do get to see the doctor, don’t be surprised if you’re rushed out of the exam room before you get all of your questions answered, according to healthcare staffing agency Staff Care. Studies show that 41% of ophthalmologists spend just 9 to 12 minutes with a patient, and 13- to 16-minute appointments are the norm for 40% of cardiologists, 37% of pediatricians, 35% of urologists, 35% of family physicians, 34% of obstetricians and gynecologists and 30% of otolaryngologists.

These names: familial pityriasis rubra pilaris and familial PRP, are used interchangeably to refer to the same condition.

The familial form of PRP is believed to be inherited in an autosomal dominant manner, meaning that a person with an affected gene has a 50% chance of passing the condition on to each of their children. However, the exact gene that causes familial PRP has not yet been identified.

While the frequency of familial PRP is low, there are other forms of PRP that are not familial and can occur sporadically. These sporadic forms of PRP are not associated with a family history of the condition and can occur in individuals with no previous history of the disease.

Genetic testing may be available for individuals with a family history of PRP. Genetic testing can help confirm a diagnosis of familial PRP and can also provide information about the inheritance pattern of the condition.

For more information about genetic testing for PRP and other rare diseases, the National Center for Advancing Translational Sciences (NCATS) provides resources and information on their website. Additionally, scientific articles and research papers on the topic can be found on PubMed and OMIM.

In summary, familial PRP is a rare condition with a frequency estimated to be between 0.5 and 1 in 1 million people. It is associated with a family history of the condition and can be confirmed through genetic testing. Additional information and resources can be found through scientific articles and advocacy organizations.

Causes

Familial pityriasis rubra pilaris (PRP) is a rare genetic skin condition that is inherited in families. It is caused by changes (mutations) in specific genes.

There are several genes that have been associated with familial PRP. Mutations in these genes can lead to abnormalities in the signaling pathways that regulate the growth and development of skin cells. As a result, individuals with familial PRP may develop thickened and scaly patches of skin, especially on the palms of the hands and soles of the feet.

PRP is also associated with other genetic diseases, such as pityriasis rubra pilaris without known genetic cause, and additional cutaneous and non-cutaneous diseases that have been reported in families with PRP. However, the frequency of these associations is not known.

Diagnosis of familial PRP is typically made through clinical evaluation and genetic testing. Genetic testing can identify mutations in the genes associated with the condition, providing a definitive diagnosis. This testing can be done at specialized genetic testing centers or through resources such as the Online Mendelian Inheritance in Man (OMIM) catalog.

For individuals and families affected by familial PRP, there are resources available for support, advocacy, and further information. These include patient support organizations, scientific articles on the genetics and inheritance of PRP, and dermatology centers with expertise in the diagnosis and management of rare skin conditions.
