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.

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.
The 11th Annual North American Genetic Analysis of ABC Transporters Workshop
Wednesday, September 24, 2014 -
Thursday, September 25, 2014
Location: NCI-Frederick,
Frederick,
MD
Description: This workshop features presentations from graduate students, post-docs., and senior investigators studying the role of ATP Cassette Binding Proteins in human disease. Phylogenetic studies, model systems, and bioinformatic techniques that shed light in this rapidly developing research area are presented. Because student presentations predominate, unpublished results often are first disclosed at these workshops.

Pseudoxanthoma Elasticum Research 2010 Conference
Monday, November 29, 2010 -
Tuesday, November 30, 2010
Location: North Bethesda Marriott ,
Bethesda,
MD
Description: The specific aims of this conference were to review the current status of basic and translational research on pseudoxanthoma elasticum (PXE), determine the most relevant biomarkers and clinical endpoints in preparation for clinical trials, and evaluate a number of hypothetical therapeutic interventions including vitamin K therapy and anti-angiogenesis therapies. Additionally, meeting participants reviewed the understanding of the clinical manifestations of PXE in order to come to consensus on diagnostic criteria. The results of the meeting will be used to plan for future research and translational applications.

Is it recommended to take an antibiotic or other medication before a dental procedure with pseudoxanthoma elasticum? See answer
My mother was diagnosed with pseudoxanthoma elasticum, but no one in the previous three generations of my father's family have been diagnosed with this condition. Now I have a baby who seems to have lumps which look like pseudoxanthoma elasticum on his neck, but no one in the previous three generations of my husband's family have been diagnosed with this condition. My questions are:
1. How can I know whether or not my husband or I are unaffected carriers? What type of blood test do I need to have?
2. Several websites say that pseudoxanthoma elasticum is untreatable. Is that true? Can the progression of this condition be slowed down or managed?
3. My baby was only 3-4 months old when I saw the yellow lumps on his neck, but I read that the average age for the onset of symptoms is in the teens. Is it possible for a baby to show symptoms?
