The ABCD4 gene, also known as the ATP-binding cassette subfamily D member 4 gene, is a genet that is listed within the registry of the OMIM database. This gene is linked to several genetic diseases, including methylmalonic acidemia and related variant homocystinuria. Mutations in the ABCD4 gene can lead to changes in the function of the gene, resulting in these conditions.

The ABCD4 gene is part of the ABC transporter superfamily, which is involved in the transport of various molecules across cell membranes. Mutations in this gene can disrupt the normal transport of methylmalonic acid and homocysteine, leading to an accumulation of these substances in the body. This can cause a range of symptoms, including developmental delay, intellectual disability, and problems with movement and coordination.

Testing for changes in the ABCD4 gene can be done through genetic testing. This can provide valuable information for the diagnosis and management of individuals with methylmalonic acidemia, homocystinuria, and related conditions. Several scientific databases, such as PubMed and OMIM, provide resources and articles with references to the ABCD4 gene and related conditions.

In conclusion, the ABCD4 gene is an important gene that is associated with genetic diseases such as methylmalonic acidemia and homocystinuria. Testing for changes in this gene can provide valuable information for the diagnosis and management of individuals with these conditions. Scientific databases and resources, such as PubMed and OMIM, provide additional information and references on the ABCD4 gene and related conditions.

Genetic changes can lead to various health conditions. Here are some examples:

  • Methylmalonic Acidemia: This is a group of genetic disorders characterized by the inability to break down certain proteins and fats. It is caused by mutations in the methylmalonic acidemia (MMA) gene. Individuals with this condition may experience symptoms such as developmental delays, seizures, and metabolic acidosis.
  • Homocystinuria: This is a genetic disorder that affects the body’s ability to process certain amino acids. It is caused by mutations in the cystathionine beta-synthase (CBS) gene. Symptoms may include intellectual disability, vision problems, and skeletal abnormalities.

It is important to note that genetic changes in the ABCD4 gene can also lead to health conditions. Testing for genetic variants within this gene may be necessary for the diagnosis and management of certain diseases.

Methylmalonic acidemia with homocystinuria

Methylmalonic acidemia with homocystinuria is a health condition caused by changes (variants) in the ABCD4 gene. This gene provides instructions for making a protein that is involved in the breakdown of a substance called methylmalonic acid. Methylmalonic acid is produced when proteins are broken down in the body. It is toxic and can build up to harmful levels, leading to the signs and symptoms of methylmalonic acidemia with homocystinuria.

Methylmalonic acidemia with homocystinuria is one type of methylmalonic acidemia, which is a group of genetic disorders characterized by the inability to break down certain proteins and fats (lipids) properly. This leads to a buildup of toxic substances in the body, including methylmalonic acid.

Other names for methylmalonic acidemia with homocystinuria include cblJ type, combined homocystinuria and methylmalonic aciduria cblJ type, combined Cbl J deficiency, and methylmalonic aciduria and homocystinuria type cblJ.

The scientific name (or gene symbol) for the ABCD4 gene is derived from the words “ATP-binding cassette, sub-family D (ALD), member 4.” This gene is part of a large family of genes that provide instructions for making proteins involved in the transport of molecules within cells. The ABCD4 protein is located in the membranes of certain cell structures called peroxisomes, where it helps transport proteins across the membrane.

Information about genetic changes to the ABCD4 gene can be found in various databases and catalogs. These resources include the Genomic Testing Registry (GTR), OMIM (Online Mendelian Inheritance in Man), PubMed, and other scientific articles. Testing for variants in the ABCD4 gene can be done through genetic testing laboratories. The results of these tests can help confirm a diagnosis of methylmalonic acidemia with homocystinuria.

OMIM classifies genes and diseases based on their relationship to each other. Genes can be listed within a disease entry if the gene is related to the disease in some way, such as a causative variant or a gene involved in the pathogenesis. Diseases can also be listed within a gene entry if the gene is associated with multiple diseases.

The catalog includes a wide range of genetic conditions, including but not limited to methylmalonic acidemia, methylmalonic aciduria, homocystinuria, and type IV methylmalonic acidemia. Each entry provides detailed information on the associated genes, proteins, and phenotypes, as well as additional resources for further reading.

OMIM provides links to related databases and resources, such as PubMed, for accessing scientific publications related to the genes and diseases of interest. The database also includes information on genetic testing labs and registries that offer testing for specific genes or diseases.

Within each entry, OMIM lists the names and variant forms of the gene or disease, as well as any relevant synonyms or alternative names. This allows for easy searching and cross-referencing of genes and diseases across different resources.

In summary, the OMIM catalog is a valuable tool for researchers, clinicians, and individuals interested in understanding the genetic basis of diseases. It provides comprehensive information on genes, diseases, and their associated phenotypes, and offers links to additional resources for further exploration.
