[show]

Mal de Meleda, also known as Meleda Disease, is a rare genetic condition that causes thick and dry skin, primarily on the palms of the hands and soles of the feet. This condition is associated with mutations in the SLURP1 gene, which is responsible for regulating the growth and development of skin cells.

Information about Mal de Meleda can be found in scientific articles on PubMed, a database of medical research. Additional resources and references can be obtained from the OMIM database, the Genetic and Rare Diseases Information Center, and other support and advocacy organizations.

Studies have shown that the inheritance of Mal de Meleda follows an autosomal recessive pattern, meaning that both parents must carry a mutated gene in order for the condition to be passed on to their child. Genetic testing can be done to confirm a diagnosis and identify specific mutations in the SLURP1 gene.

Mal de Meleda is often diagnosed based on clinical examination of the patient’s skin and nails. Symptoms usually appear during early childhood and can include thickening of the skin, hyperkeratosis, and the formation of scales and plaques. In some cases, other parts of the body, such as the elbows, knees, and buttocks, may also be affected.

Although there is currently no cure for Mal de Meleda, treatment options focus on managing symptoms and preventing complications. This may include the use of moisturizers, keratolytic agents, and other topical treatments to soften the skin and reduce scaling. Regular follow-up with a dermatologist is recommended to monitor the progression of the condition and adjust treatment as needed.

In conclusion, Mal de Meleda is a rare genetic condition that causes thick and dry skin primarily on the palms of the hands and soles of the feet. It is associated with mutations in the SLURP1 gene and follows an autosomal recessive inheritance pattern. While there is currently no cure, there are treatment options available to manage symptoms and improve quality of life for patients with this condition.

It’s not just health insurance premiums, but also deductibles, that keep on rising. In 2018, the average deductible was $3,000 for a gold-tier family plan, $8,000 for a silver-tier family plan and $12,000 for a bronze-tier family plan, according to USC Annenberg’s Center for Health Journalism.

Frequency

Mal de Meleda is a rare condition, with a frequency estimated to be less than 1 in 1 million individuals worldwide. It is considered to be one of the rarest keratoderma diseases.

Not much information is available about the frequency of Mal de Meleda due to its rarity. However, scientific articles and studies on this condition can be found on PubMed, a database of scientific literature.

Additional information about Mal de Meleda and its frequency can be found in the following PubMed references:

It is important to note that Mal de Meleda is a rare condition, and more research and awareness are needed to better understand its frequency and inheritance patterns.

Causes

The condition known as Mal de Meleda is a rare genetic disorder. It is associated with mutations in the SLURP1 gene. SLURP1 is also known as the ARS component B protein.

Mal de Meleda is inherited in an autosomal recessive manner, which means that both copies of the SLURP1 gene must have mutations in order for the condition to develop. When both parents are carriers of the SLURP1 gene mutation, there is a 25% chance of their child having Mal de Meleda.

Scientific studies and research articles have provided more information on the causes of Mal de Meleda. Studies have shown that the SLURP1 gene plays a role in the normal development and functioning of the skin. Mutations in this gene lead to a thickening of the skin on the palms of the hands and soles of the feet, which are characteristic features of Mal de Meleda.

According to references from the National Center for Biotechnology Information (NCBI) and the Online Mendelian Inheritance in Man (OMIM) catalog, SLURP1 mutations have been found to be the cause of Mal de Meleda in many affected individuals.

Further testing of genes associated with other rare diseases is also important for genetic counseling. Additional references from PubMed, the NCBI Genetic Testing Registry, and patient advocacy groups can provide more support, information, and resources for understanding the causes and frequency of Mal de Meleda.

Inheritance

The Mal de Meleda condition is inherited in an autosomal recessive manner. This means that both parents of an affected individual carry a single copy of the mutated gene, known as SLURP1. Each parent passes on one copy of the mutated gene to their child. To develop the Mal de Meleda condition, a person must inherit two mutated copies of the SLURP1 gene, one from each parent.

SLURP1 is the gene associated with Mal de Meleda and is located on chromosome 8. Mutations in this gene lead to the thickening of the skin on the palms of the hands and soles of the feet, as well as other symptoms associated with the condition.

The inheritance pattern of Mal de Meleda follows what is known as an autosomal recessive inheritance. This means that both males and females are equally affected by the condition, and individuals who carry only one copy of the mutated gene are unaffected carriers.

If both parents are carriers of a single mutated SLURP1 copy, there is a 25% chance with each pregnancy that their child will inherit two copies of the mutated gene and have Mal de Meleda. There is a 50% chance that the child will also be a carrier of the mutated gene, and a 25% chance that the child will not inherit any mutated copies of the gene.

Genetic testing can be performed to confirm a diagnosis of Mal de Meleda. Testing can also be done to determine if individuals are carriers of the mutated gene. Genetic counseling is often recommended for individuals and families affected by Mal de Meleda to better understand the inheritance pattern and to provide support and resources.

Mal de Meleda is a rare genetic condition associated with mutations in the SLURP1 gene. It has several other names:

Mal de Meleda
Palmoplantar Keratoderma, Mal de Meleda Type
Palmoplantar Keratoderma, Diffuse Type VII
Meleda Disease
Palmoplantar Keratoderma Type IV

These names are used interchangeably and refer to the same condition.

The condition is so rare that it has only been reported in a few individuals and families worldwide. It is estimated to have a frequency of less than 1 in 1,000,000 people.

Mal de Meleda is characterized by thick, yellowish skin on the palms of the hands and the soles of the feet. In some cases, the skin changes may extend to the wrists, ankles, and toes. The thickened skin can cause discomfort and may limit the movement of the fingers and toes.

The condition is inherited in an autosomal recessive manner, which means that both copies of the SLURP1 gene must be mutated for the condition to occur. If both parents carry a mutation in the SLURP1 gene, each of their children has a 25% chance of inheriting the condition.
