Abnormalities of the fingers and toes have also been reported. These may include webbing or fusion of the fingers and toes (syndactyly). The severity of the syndactyly may be variable, ranging from webbing of skin and other soft tissues to fusion of bone within the affected fingers or toes. Affected individuals can also have extra fingers and/or toes (polydactyly). In addition, the fingers and toes may appear unusually short (brachydactyly), particularly due to abnormalities of the bones within the hands and feet.[3][2]
Some individuals may have additional physical abnormalities including delayed bone age, incomplete closure of the roof of the mouth (cleft palate), and a dislocated elbow. In some affected males, the testes may fail to descend into the scrotum (cryptorchidism). In one report, skin and teeth abnormalities were also noted.[3][2]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. Suggest an organization to add.
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.
