Shprintzen–Goldberg syndrome

Autosomal dominant - en

Shprintzen–Goldberg syndrome (SGS) is a rare genetic disorder characterized by a combination of distinctive facial features, skeletal abnormalities, and various other physical and developmental anomalies. It was first described by Robert Shprintzen and Richard Goldberg in 1982.

Signs and Symptoms

Individuals with Shprintzen–Goldberg syndrome typically present with a range of symptoms, which may include:

• Craniosynostosis (premature fusion of skull bones)
• Marfanoid habitus (tall stature, long limbs, and fingers)
• Arachnodactyly (long, slender fingers and toes)
• Scoliosis (curvature of the spine)
• Joint hypermobility
• Cardiovascular anomalies, such as aortic root dilation
• Intellectual disability or developmental delays
• Distinctive facial features, including a high forehead, widely spaced eyes (hypertelorism), down-slanting palpebral fissures, and a small jaw (micrognathia)

Genetics

Shprintzen–Goldberg syndrome is typically caused by mutations in the SKI gene, which plays a role in the TGF-beta signaling pathway. This pathway is crucial for the regulation of cell growth and development. The syndrome is inherited in an autosomal dominant manner, meaning that a single copy of the mutated gene is sufficient to cause the disorder.

Diagnosis

Diagnosis of Shprintzen–Goldberg syndrome is based on clinical evaluation, identification of characteristic physical features, and genetic testing to confirm mutations in the SKI gene. Prenatal diagnosis may be possible if a known mutation is present in the family.

Treatment

There is no cure for Shprintzen–Goldberg syndrome, and treatment is primarily supportive and symptomatic. Management may involve:

• Surgical intervention for craniosynostosis and scoliosis
• Regular monitoring and management of cardiovascular issues
• Physical therapy to improve joint mobility and muscle strength
• Educational support and developmental therapies for intellectual disabilities

Prognosis

The prognosis for individuals with Shprintzen–Goldberg syndrome varies depending on the severity of symptoms and associated complications. With appropriate medical care and support, many individuals can lead relatively normal lives.
