Definition
Guttmacher syndrome is an extremely rare syndrome characterized by hypoplastic thumbs and halluces, 5th finger clinobrachydactyly, postaxial polydactyly of the hands, short or uniphalangeal 2nd toes with absent nails and hypospadias.

Epidemiology
It has been described in a father and his son and daughter.

Clinical description
The affected patients have normal mental development. Except for postaxial polydactyly of the hands and uniphalangeal 2nd toes with absent nails, features are in common with hand-foot-genital syndrome (HFGS, see this term) caused by mutations in the HOXA13 gene.

Etiology
In all three affected individuals with Guttmacher syndrome, two different sequence alterations were identified in HOXA13 gene: a de novo missense mutation and a deletion in the promoter region of the gene, inherited from an unaffected parent, which may contribute to the phenotype in the affected individuals.

Genetic counseling
The condition is inherited in an autosomal dominant manner.

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.

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.
