Hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis (poiktmp)

is a rare genetic condition characterized by the progressive development of skin abnormalities, joint contractures, muscle weakness, and lung scarring. It is also known as poikiloderma with tendon contractures and pulmonary fibrosis. The condition is caused by mutations in the FAM111B gene, which is involved in the production of a protein that plays a role in maintaining the structure and function of skin and muscle tissue.

The exact frequency of hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis is unknown, but it is considered to be a rare condition. The onset of symptoms typically occurs in childhood or adolescence, although some cases have been reported in infancy or adulthood. In addition to skin abnormalities, joint contractures, muscle weakness, and lung scarring, other features of the condition may include sparse hair, hypohidrosis (reduced sweating), and nail abnormalities.

Diagnosis of hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis is based on the presence of characteristic symptoms and the identification of mutations in the FAM111B gene through genetic testing. Additional testing, such as skin biopsies or imaging studies, may be used to support the diagnosis and assess the extent of involvement of the skin, joints, muscles, and lungs.

Treatment for hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis is focused on managing the symptoms and providing supportive care. This may include physical and occupational therapy to help maintain mobility and prevent further contractures, respiratory support for lung function, and regular monitoring for the development of complications. There is currently no cure for the condition.

More information about hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis can be found through advocacy and support organizations, scientific articles, and resources such as the Online Mendelian Inheritance in Man (OMIM) and PubMed. References and additional resources for patients and healthcare professionals can also be obtained from the Genetic and Rare Diseases Information Center (GARD) and the National Center for Biotechnology Information (NCBI) Genes and Diseases database.

Pre-tax flexible spending accounts (FSAs) are often touted as the answer to high out-of-pocket medical costs, but many FSAs have “use it or lose it” rules. FSA holders lose $50 to $100 per year on average, CBS News reported, but since you’re allowed to contribute up to $2,650, you could risk losing thousands of dollars if you don’t spend your FSA money in time.

Frequency

The frequency of hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis (POIKTMP) is currently unknown. It is considered to be a rare condition, with fewer than 20 articles published on this topic. POIKTMP is also known by other names, including fibrosing poikiloderma with tendon contractures, restrictive dermopathy, and Figarella-Branger myopathy.

This condition has a genetic basis and is inherited in an autosomal recessive manner. Mutations in the FAM111B gene have been identified as the cause of POIKTMP. Additional genes may also be associated with this condition, but further testing is needed to learn more about these genetic causes.

POIKTMP is characterized by skin abnormalities, including poikiloderma (patchy skin pigmentation), hypohidrosis (reduced sweating), and sparse hair. Tendon contractures, or the inability to fully extend or flex certain joints, are another hallmark feature of this condition. Myopathy, or muscle weakness, and pulmonary fibrosis, or scarring of lung tissue, are also common problems found in individuals with POIKTMP.

Due to its rarity, there is limited information available on the frequency of this condition. The Online Mendelian Inheritance in Man (OMIM) catalog is a valuable resource for information on genetic diseases, including POIKTMP. Genetic testing can be performed to confirm a diagnosis of POIKTMP and identify any underlying genetic mutations.

Support and additional information for individuals with POIKTMP and their families can be obtained from patient support organizations and scientific research centers. PubMed is another useful resource for finding articles and references about this condition.

Causes

Hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis (POIKTMP) is a rare condition that occurs due to genetic causes. It is also known as Figarella-Branger syndrome.

This condition is caused by mutations in the FAM111B gene, which is responsible for encoding a protein called FAM111B. The exact role of this protein in the development of POIKTMP is still not fully understood, but it is believed to play a role in the maintenance of cell structure and function.

POIKTMP has an autosomal recessive inheritance pattern, which means that an individual must inherit two copies of the mutated gene (one from each parent) to develop the condition. Individuals who inherit only one copy of the mutated gene are known as carriers and typically do not show any symptoms.

Other rare causes of fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis have also been reported, but they are not well understood. Further research is needed to determine the underlying genetic causes of these conditions.

It is important to note that not all individuals with a mutation in the FAM111B gene will develop POIKTMP. The frequency of this condition is currently unknown, as it is extremely rare.

For more information about the genetic causes of POIKTMP and other related conditions, you may visit the OMIM database or other scientific references. The OMIM entry for this condition is OMIM #615704.

Hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis is a rare genetic condition that causes a variety of symptoms. The condition is also known by other names such as hereditary fibrosing poikiloderma with tendon contractures, OMIM 127300, and poikTMP.

One of the genes associated with this condition is the FN1 gene. The FN1 gene provides instructions for making a protein called fibronectin. This protein is involved in the formation of connective tissue, which supports and connects various organs and tissues in the body.

Mutations in the FN1 gene can cause abnormalities in the fibronectin protein, leading to the development of hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis. These mutations are typically inherited in an autosomal dominant manner, which means that only one copy of the mutated gene is needed for the condition to occur.

Diagnosis of this condition can be challenging due to its rarity and overlapping symptoms with other diseases. Genetic testing can be conducted to identify mutations in the FN1 gene, which can help confirm the diagnosis. Additional testing, such as skin biopsy, may also be performed to gather more information about the specific characteristics of the condition in a patient.

Hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis is a progressive condition with no known cure. Treatment aims to manage the symptoms and may involve physical therapy, medications, and supportive measures to address specific complications such as pulmonary fibrosis and tendon contractures.

Further research is needed to better understand the underlying mechanisms and genetic factors associated with this condition. The identification of additional genes or genetic factors may provide further insights into the causes and potential treatment options for hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis.

For more information about this rare condition, you can visit resources such as OMIM (Online Mendelian Inheritance in Man), which provides comprehensive information about genes and genetic disorders. The National Center for Advancing Translational Sciences (NCATS) can also be a valuable resource for finding research articles and references related to hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis.

Inheritance

Inheritance of hereditary fibrosing poikiloderma with tendon contractures, myopathy, and pulmonary fibrosis (POIKTMP) is autosomal recessive, which means that both copies of the gene in each cell have mutations. The gene associated with this condition is called the ATP7A gene.

Most cases of POIKTMP are caused by mutations in the ATP7A gene. Mutations in this gene can disrupt the function of ATP7A, which is responsible for transporting copper within cells. Without proper copper transport, cells cannot produce certain enzymes that are necessary for the normal development and function of connective tissue, muscles, and other tissues throughout the body.

The ATP7A gene mutations that cause POIKTMP typically result in reduced copper levels, leading to the accumulation of fats and other substances in cells. This accumulation can cause widespread tissue damage, leading to the various signs and symptoms of the condition.

This disease is very rare and only a few cases have been reported in the medical literature. It was first described by Thauvin et al. in 2014, and is also known as Thauvin-Robinet-Faivre syndrome (TRF). Other names for this condition include: hereditary fibrosing poikiloderma, tendon contractures, myopathy, and pulmonary fibrosis syndrome (OMIM: #615704) and Hereditary Fibrosing Poikiloderma, Tendon Contractures, Myopathy, and Pulmonary Fibrosis (OMIM: #615704).

Diagnosis of POIKTMP can be confirmed through genetic testing, in which the ATP7A gene is analyzed for mutations. Additional testing may also be done to evaluate the extent of organ involvement and assess the progression of the disease.

For more information about this rare condition, patients and healthcare providers can contact advocacy organizations, such as the Genetic and Rare Diseases Information Center (GARD) or the National Organization for Rare Disorders (NORD), which have resources and support for individuals and families affected by POIKTMP.

Catalog of Genes and Diseases from OMIM

The Catalog of Genes and Diseases from OMIM is a valuable resource for information about hereditary rare diseases. It provides scientific articles, genetic testing resources, and additional support for patients and advocacy groups.

One rare hereditary condition found in the catalog is Hereditary fibrosing poikiloderma with tendon contractures myopathy and pulmonary fibrosis (abbreviated as POIKTMP). This condition is characterized by the occurrence of fibrosis in multiple tissues, including the lungs, and is associated with tendon contractures and muscle weakness.

The genes associated with this condition include the TTM gene, which codes for a peptidase, and the FKTN gene, which codes for a protein involved in muscle function. Mutations in these genes can cause the symptoms of POIKTMP.

Patients with POIKTMP may experience problems with their skin, including hypohidrosis (reduced sweating) and the development of poikiloderma (patches of discolored skin). They may also have muscle weakness and limited mobility due to the contractures in their tendons.

Pulmonary fibrosis is a key feature of POIKTMP, leading to progressive scarring of the lung tissue and breathing difficulties. It is important for patients with this condition to receive regular medical monitoring and treatment for their pulmonary symptoms.

The inheritance pattern of POIKTMP is not yet fully understood, but it is believed to be an autosomal recessive condition. This means that individuals with the condition have inherited one copy of the mutated gene from each of their parents.

If you would like to learn more about POIKTMP or other rare diseases, the OMIM database provides a wealth of information. It includes clinical descriptions, inheritance patterns, and references to scientific articles and resources such as PubMed.
