The signs and symptoms of hyperlipoproteinemia type 1 usually begin during childhood. Approximately 25 percent of affected individuals develop symptoms before age 1. The characteristic features of hyperlipoproteinemia type 1 include:
The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
|Signs and Symptoms||Approximate number of patients (when available)|
|Autosomal recessive inheritance||-|
|Episodic abdominal pain||-|
Hyperlipoproteinemia type 1 is caused by mutations in the LPL gene. This gene provides instructions for producing an enzyme called lipoprotein lipase. This enzyme helps break down fats called triglycerides, which are carried by molecules called lipoproteins.
Mutations in the LPL gene lead to a reduction or elimination of lipoprotein lipase activity, which prevents the enzyme from effectively breaking down triglycerides. As a result, triglycerides attached to lipoproteins build up in the blood and tissues, leading to the signs and symptoms of hyperlipoproteinemia type 1.
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.
Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Nonprofit support and advocacy groups bring together patients, families, medical professionals, and researchers. These groups often raise awareness, provide support, and develop patient-centered information. Many are the driving force behind research for better treatments and possible cures. They can direct people to research, resources, and services. Many groups also have experts who serve as medical advisors. Visit their website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
Living with a genetic or rare disease can impact the daily lives of patients and families. These resources can help families navigate various aspects of living with a rare disease.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.
Fifth International Meeting of Gene and Cell Therapies for Arthritis and Related Diseases
Tuesday, April 29, 2008 -
Thursday, May 1, 2008
Location: Bell Harbor Conference Center, Seattle, WA
Description: The goals of this meeting were to share advances in cellular biology that offer the opportunity to harness regulatory immune cells to combat autoimmune disease, to harness the use of multipotent progenitor cells to augment tissue regeneration and repair, and to accelerate the development of molecular and cellular therapies for rheumatologic and orthopaedic disorders. The GTARD conference series was initiated 9 years ago as a dedicated forum for investigators performing research in these areas to review and discuss scientific progress and to share ideas and technologies. Proceedings from the first three meetings have been published and proceedings from the 2006 meeting are currently in revision. The proceedings from this meeting will be similarly published.

I was born with hyperlipoproteinemia type 1, and I would like more information on my disease. I have been pretty much on my own due to lack of knowledge by my doctors. See answer
