【 摘 要 】

Carney complex is a rare disease inherited in an autosomal dominant manner. It is mostly caused by inactivating mutations of the subunit of protein kinase A. Carney complex is associated with atrial myxoma, nevi or myxomas of the skin, breast tumor and endocrine overactivity. Primary pigmented nodular adrenocortical disease is the specific endocrine manifestation. The authors present the history of a 53-year-old female patient who had undergone surgery for atrial myxomas, thyroid tumor and breast cancer. She was also operated for an adrenal adenoma causing Cushing’s syndrome. Genetic study revealed a novel mutation in the regulatory subunit of protein kinase A (ivs2-1G>A splice mutation in intron 2). Her heterozygous twins were also genetically screened and one of them carried the same mutation. The authors emphasize that despite the absence of specific treatment for patients with Carney complex, confirmation of the diagnosis by genetic studies is important for the close follow-up of the patient and early identification of novel manifestations.
