Acropectoral syndrome

Diagram of autosomal dominant inheritance

Acropectoral syndrome is a rare genetic disorder characterized by the presence of congenital limb and chest wall abnormalities. It is inherited in an autosomal dominant pattern, meaning that a single copy of the altered gene in each cell is sufficient to cause the disorder.

Clinical Features

Individuals with acropectoral syndrome typically present with a combination of limb and chest wall malformations. The most common features include:

• Syndactyly: Fusion of two or more fingers or toes.
• Polydactyly: Presence of extra fingers or toes.
• Pectus excavatum: A sunken appearance of the chest due to a depression of the sternum.
• Pectus carinatum: A protrusion of the chest over the sternum, giving a "pigeon chest" appearance.

Genetics

Acropectoral syndrome is caused by mutations in specific genes that are involved in the development of the limbs and chest wall. The disorder follows an autosomal dominant inheritance pattern, which means that an affected individual has a 50% chance of passing the condition on to their offspring.

Diagnosis

Diagnosis of acropectoral syndrome is primarily based on clinical evaluation and the identification of characteristic physical features. Genetic testing can confirm the diagnosis by identifying mutations in the associated genes.

Management

Management of acropectoral syndrome is typically focused on addressing the specific physical abnormalities present in the individual. This may include:

• Surgical correction of syndactyly or polydactyly to improve function and appearance.
• Surgical intervention for severe chest wall deformities, such as pectus excavatum or pectus carinatum, to improve respiratory function and cosmetic appearance.

Prognosis

The prognosis for individuals with acropectoral syndrome varies depending on the severity of the physical abnormalities and the presence of any associated complications. With appropriate management, many individuals can lead normal, healthy lives.
