Alpha-mannosidosis is a rare genetic condition that is characterized by the deficiency of the enzyme alpha-mannosidase. This enzyme is responsible for breaking down complex sugar molecules in the body. Without enough of this enzyme, sugars accumulate in various tissues and cause progressive deterioration. Alpha-mannosidosis is inherited in an autosomal recessive manner, which means that both parents must carry a copy of the faulty gene for the condition to appear in their child.
The signs and symptoms of alpha-mannosidosis can vary widely from person to person. Some individuals may have a milder form of the condition that appears in late childhood or adulthood, while others may have a more severe form that begins in infancy. Common symptoms include intellectual disability, skeletal abnormalities, hearing loss, and recurrent infections.
There is currently no cure for alpha-mannosidosis, but supportive care can help manage the symptoms and improve quality of life. Treatment options may include enzyme replacement therapy, hematopoietic stem cell transplantation, and symptomatic care for specific symptoms. Ongoing research and clinical trials are exploring new treatment approaches and potential gene therapies for alpha-mannosidosis.
If you or someone you know has been diagnosed with alpha-mannosidosis, it is important to seek support and information. There are several organizations and resources available that can provide additional information, connect you with other patients and families, and offer advocacy and support. Some helpful resources include the National Institutes of Health’s Genetic and Rare Diseases Information Center, the Online Mendelian Inheritance in Man (OMIM) catalog, PubMed for scientific articles and research studies, and clinicaltrialsgov for information on clinical trials and ongoing research.
Genetic testing is available to confirm a diagnosis of alpha-mannosidosis and to identify the specific gene mutations. This information can be helpful for understanding the inheritance pattern, providing genetic counseling, and making informed decisions about family planning. If you suspect that you or your child may have alpha-mannosidosis, it is recommended to consult with a geneticist or genetic counselor for further evaluation and testing.
Frequency
Alpha-mannosidosis is a rare inherited genetic condition with a frequency of approximately 1 in 500,000 to 1 in 1,000,000 live births. It is caused by mutations in the MAN2B1 gene.
Just under half – 49% – of Americans get their health insurance through their employer, according to the Henry J. Kaiser Family Foundation. Another 19% of Americans are insured under Medicaid, 14% under Medicare, seven% under non-group plans and two% under other public insurers, while nine% of U.S. citizens remain uninsured.
The frequency of alpha-mannosidosis may vary in different populations and countries due to differences in genetic inheritance and testing methods. Therefore, it is important to consult scientific articles and references for more accurate information on the frequency of this condition.
Alpha-mannosidosis is associated with a range of clinical features that can appear at different ages. The onset and severity of symptoms may vary from person to person. Additional causes of the condition and its associated genetic factors are still under research.
Genetic testing can be used to diagnose alpha-mannosidosis. This testing involves analyzing the MAN2B1 gene to identify potential mutations. It is recommended for individuals with symptoms of the condition, as well as for family members of diagnosed patients.
Patient advocacy groups, such as the Alpha-Mannosidosis International Patients and Families Association, provide support and resources for individuals and families affected by alpha-mannosidosis. These organizations may offer information about genetic testing, clinical trials, and research on alpha-mannosidosis.
References to scientific articles, OMIM database, PubMed, and other reliable sources can provide more detailed information about the frequency of alpha-mannosidosis, its clinical features, and available treatment options.
Research studies are ongoing to learn more about the cause, inheritance patterns, and treatment strategies for alpha-mannosidosis. The clinicaltrials.gov website is a valuable resource for information on ongoing clinical trials and studies related to this rare condition.
Causes
Alpha-mannosidosis is a rare genetic disorder that is caused by mutations in the MAN2B1 gene. This gene provides instructions for producing an enzyme called alpha-mannosidase.
These mutations can result in reduced or absent levels of alpha-mannosidase, leading to the accumulation of certain complex carbohydrates called mannose-rich oligosaccharides in the body’s cells and tissues.
Alpha-mannosidosis is inherited in an autosomal recessive pattern, which means that an individual must inherit two copies of the mutated gene (one from each parent) in order to develop the disorder.
The onset and severity of alpha-mannosidosis can vary widely among affected individuals. Some individuals may have a mild form of the disorder, while others may experience more severe symptoms.
There are currently no known environmental or lifestyle factors that are associated with an increased risk of developing alpha-mannosidosis.
For more information about the genetic cause of alpha-mannosidosis, you can visit the OMIM (Online Mendelian Inheritance in Man) website, which provides a comprehensive catalog of human genes and genetic disorders. Additional resources can be found through advocacy organizations, research articles, and scientific studies.

Inheritance
The genetic inheritance of alpha-mannosidosis follows an autosomal recessive pattern, which means that individuals inherit two copies of the disease-causing gene, one from each parent. Typically, both parents of an affected individual are carriers of the mutated gene, but they do not show any signs or symptoms of the condition.
The alpha-mannosidosis gene is located on chromosome 19 and mutations in the gene lead to a deficiency of the enzyme alpha-mannosidase. This deficiency results in the accumulation of substances called oligosaccharides in various tissues of the body, leading to the characteristic features and clinical symptoms of the condition.
The OMIM database, a catalog of human genes and genetic disorders, provides detailed information about the specific genes associated with alpha-mannosidosis. Additional information about the genetic basis of the condition can also be found in scientific articles and references on PubMed.
Genetic testing can be used to confirm a diagnosis of alpha-mannosidosis and identify the specific mutations in the alpha-mannosidase gene. This can help with genetic counseling and provide information about the likelihood of having a child with the condition.
Alpha-mannosidosis is a rare genetic disorder, with an estimated frequency of 1 in 500,000 to 1 in 1,000,000 births. However, the frequency may vary in different populations and regions.
There are no known ways to prevent or cure alpha-mannosidosis, but supportive care and management can help alleviate symptoms and improve the quality of life for affected individuals. Clinical trials and research studies are ongoing to learn more about the condition and develop potential treatments.
Advocacy groups and organizations, such as the National Organization for Rare Disorders (NORD), can provide support, resources, and information for individuals and families affected by alpha-mannosidosis.
