Polysyndactyly is a rare genetic disorder characterized by the presence of extra fingers or toes and webbing between them. This condition is a combination of Polydactyly and Syndactyly, hence the name Polysyndactyly.

Causes

Polysyndactyly is caused by genetic mutations. It is usually inherited in an Autosomal dominant manner, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits the mutation from one affected parent. Other cases may result from new mutations in the gene. These cases occur in people with no history of the disorder in their family.

Symptoms

The primary symptom of Polysyndactyly is the presence of extra fingers or toes. These can occur on one or both hands or feet. The extra digits may be fully formed and functional, partially formed, or simply a small, raised bump of skin. In addition to extra digits, webbing or fusion of the fingers or toes (syndactyly) may also occur.

Diagnosis

Polysyndactyly is usually diagnosed at birth based on the physical appearance of the hands and feet. In some cases, the condition may be detected before birth during a routine ultrasound examination. Genetic testing may be used to confirm the diagnosis and identify the specific gene mutation.

Treatment

Treatment for Polysyndactyly depends on the severity of the condition and the presence of other health problems. In some cases, surgery may be used to remove the extra digits and separate the fused fingers or toes. Physical and occupational therapy may be needed to improve hand and foot function.
