Lysosomal acid lipase deficiency

Summary Summary

Wolman disease is a congenital disease characterized by an impaired metabolism of the fats (lipids). It is the most severe type of lysosomal acid lipase deficiency.^[1] The lysomal acid lipase deficiency causes a buildup of lipids (fats) in body organs and calcium deposits in the adrenal glands. Common symptoms in infants include enlarged liver and spleen, poor weight gain, low muscle tone, jaundice, vomiting, diarrhea, developmental delay, anemia, and poor absorption of nutrients from food. Wolman disease is caused by mutations in the LIPA gene which provides instructions to make the lysosomal acid lipase. Inheritance is autosomal recessive.^[2] The disease is severe and life-threatening, however enzyme replacement therapy, available for the treatment of lysosomal acid lipase deficiencies, in the United States, the European Union, and Japan, have shown improvement of symptoms, including liver problems, as well as an increased life expectancy.^[3] Liver transplantation can be considered in some cases when the liver disease is severe. Reports of treatment with bone marrow transplantation have shown mixed results, correcting the metabolic disease in a few cases, but not in others.^[1]^[4]

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Diagnosis Diagnosis

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

Testing Resources

The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

Treatment Treatment

You can find relevant journal articles on Wolman syndrome and its treatment through a service called PubMed, a searchable database of medical literature. Information on finding an article and its title, authors, and publishing details is listed here. Some articles are available as a complete document, while information on other studies is available as a summary abstract. To obtain the full article, contact a medical/university library (or your local library for interlibrary loan), or order it online using the following link. Using "Wolman syndrome[ti] treatment" as your search term should locate articles. To narrow your search, click on the “Limits” tab under the search box and specify your criteria for locating more relevant articles. Click here to view a search.

The National Library of Medicine (NLM) Web site has a page for locating libraries in your area that can provide direct access to these journals (print or online). The Web page also describes how you can get these articles through interlibrary loan and Loansome Doc (an NLM document-ordering service). You can access this page at the following link http://nnlm.gov/members/. You can also contact the NLM toll-free at 888-346-3656 to locate libraries in your area.
