Causes

The Nager syndrome, also known as Nager acrofacial dysostosis, is a rare genetic condition that affects the development of the face, hands, and airway. It is named after the American physician Frances Nager, who first described the syndrome in 1948.

The exact causes of Nager syndrome are unknown, but it is believed to be caused by changes in certain genes. Genetic studies have identified mutations in the SF3B4 gene in some individuals with Nager syndrome. However, not all individuals with Nager syndrome have mutations in this gene, suggesting that other genes may also be involved.

Research is ongoing to learn more about the genetic causes of Nager syndrome. By studying affected individuals and their families, scientists hope to identify additional genes and genetic changes that contribute to the condition.

Although the exact inheritance pattern of Nager syndrome is unclear, it is thought to be caused by a combination of genetic and environmental factors. Most cases of Nager syndrome occur sporadically, meaning they are not inherited from a parent. However, affected individuals may have a copy of the gene associated with Nager syndrome that increases their risk of developing the condition.

Diagnosis of Nager syndrome is typically based on the presence of characteristic features and clinical evaluation. Genetic testing may be available to confirm the diagnosis and identify the specific genetic changes associated with the condition. Testing may involve sequencing the SF3B4 gene as well as other genes that have been associated with similar syndromes.

Nager syndrome can have a wide range of physical and developmental effects. Common features include underdeveloped cheekbones, a small lower jaw, and malformed or missing ears. Individuals with Nager syndrome may also have hand abnormalities, such as missing or deformed thumbs. These physical features can vary widely from person to person affected by Nager syndrome.

While there is currently no cure for Nager syndrome, treatment focuses on managing the symptoms and improving quality of life. This may involve surgeries to improve breathing, hearing, and facial appearance. Early intervention and ongoing support from a multidisciplinary team, including specialists in genetics, craniofacial surgery, and rehabilitation, can help individuals with Nager syndrome reach their full potential.

There are several resources available for individuals and families affected by Nager syndrome. Organizations such as the Nager and Miller Syndrome Support and Advocacy Group provide information, support, and resources for individuals and families affected by these conditions.
