Causes
The exact cause of Hajdu-Cheney syndrome is not fully understood. Researchers believe that the syndrome may be caused by mutations in the NOTCH2 gene, which provides instructions for making a protein called Notch2. This protein plays a role in various developmental processes, including the formation and remodeling of bones, the brain, and the kidneys.
Genetic studies have identified specific mutations in the NOTCH2 gene in some individuals with Hajdu-Cheney syndrome. These mutations can disrupt the normal function of the Notch2 protein, leading to the signs and symptoms associated with the syndrome.
Research continues to learn more about the causes of Hajdu-Cheney syndrome. Studies have shown that there is a wide range of mutations in the NOTCH2 gene, and the specific mutation in each patient may determine the severity and progression of the disease.
There is also evidence to suggest that Hajdu-Cheney syndrome has an autosomal dominant pattern of inheritance, meaning that a mutation in one copy of the gene is sufficient to cause the condition. In some cases, the syndrome can occur sporadically, meaning that there is no family history of the disease.
Further testing and research are needed to fully understand the underlying causes of Hajdu-Cheney syndrome and its inheritance patterns.
