Summary Summary


Listen
The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.
orphanet

Orpha Number: 3329

Definition
Tibial aplasia-ectrodactyly syndrome is a rare condition characterized by congenital ectrodactylous limb malformations associated with tibial aplasia or hypoplasia.

Epidemiology
The incidence is estimated to be approximately 1 in 1,000,000 live births.

Clinical description
The expression of the phenotype is highly variable and ranges from bilateral aplasia of tibiae and split-hand/split-foot deformity (tetramonodactyly or transverse hemimelia) to the mildest visible manifestation, hypoplastic big toes. Additional malformations may include distal hypoplasia or bifurcation of femora, hypo- or aplasia of ulnae, and minor anomalies such as aplasia of patellae, postaxial and intermediate polydactyly in association with split-hand deformity, and cup-shaped ears.

Etiology
Two susceptibility loci at 1q42.2-q43 and 6q14.1 have been identified, leading to the hypothesis that this syndrome fits the model of digenic inheritance.

Differential diagnosis
Overlap with the Gollop-Wolfgang syndrome (see this term) has been described.

Genetic counseling
The syndrome is generally inherited in an autosomal dominant manner with reduced penetrance. Autosomal recessive inheritance has also been proposed in some families.

Symptoms Symptoms


Listen

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.

Find a Specialist Find a Specialist


Listen

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

  • To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from Genetics Home Reference.

Research Research


Listen

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.

Clinical Research Resources

  • The Centers for Mendelian Genomics program is working to discover the causes of rare genetic disorders. For more information about applying to the research study, please visit their website.

Organizations Organizations


Listen

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
