Introduction: Bilateral macronodular adrenal disease (BMAD) is a genetically heterogeneous disease that can be caused by ARMC5 or KDM1A alterations. Indeed, a germline and somatic event leading to a bi-allelic inactivation of ARMC5 or KDM1A are responsible for 20 and 1% of BMAD cases, respectively. Genetic analysis identified three molecular groups: ARMC5, KDM1A and no genetic cause known to date. Although there is a high h...

Introduction: PBMAH is an heterogeneous disease from the clinical, hormonal, and morphological point of view. ARMC5 inactivating mutations have been reported as a cause of PBMAH. PDE11A4 variants have been associated with PBMAH and NR3C1 variants with bilateral adrenal incidentalomas.Aim: To analyse the frequency of ARMC5 pathogenic mutations and PDE11A4 and NR3C1 variants in PBMAH patients.<p cla...

Introduction: Bilateral Macronodular Adrenocortical Disease (BMAD) is a rare cause of Cushing syndrome due to bilateral adrenocortical macronodules. Germline inactivating variants of the tumor suppressor gene ARMC5 have been described by our group 10 years ago and are responsible for 20-25% of apparently sporadic BMAD cases and 80% of familial presentations. ARMC5 patients present with a more pronounced phenotype than wild-type patients, in terms of cortisol ...

Increased frequency of breast cancer in young Carney Complex patients suggests a role for inactivation of the tumor suppressor gene PRKAR1A

Objective: Carney Complex (CNC) is a rare hereditary genetic syndrome, mostly due to inactivating pathogenic variants of the tumor suppressor gene PRKAR1A. It has a wide spectrum of manifestations with frequent pigmented skin lesions, cardiac myxomas, primary pigmented nodular adrenocortical dysplasia, acromegaly and thyroid cancers. Breast benign tumors (fibroadenomas, ductal adenomas and myxoid lesions) have been associated with CNC, but so far, association with mal...

Introduction: Carney Complex (CNC) is a rare genetic syndrome, with multiple endocrine and non-endocrine neoplasia, mostly due to inactivating mutations of the PRKAR1A gene. CNC has a wide spectrum of manifestations : most frequently skin lesions, cardiac myxomas and primary pigmented nodular adrenocortical dysplasia (PPNAD), but also thyroid nodules, schwannomas, breast tumors (mainly myxoid fibroadenomas and ductal adenomas)… The present study was designed to ...

IntroductionPrimary bilateral macronodular adrenal hyperplasia (PBMAH), the most common cause of adrenal Cushing’s syndrome due to bilateral adrenal tumors, is an heterogenous disease with various clinical, hormonal and morphological characteristics. ARMC5 inactivating mutations is the most frequent genetic cause of PBMAH and variants of PDE11A4 have been associated with the disease. In order to better understand the heterogeneity ...

Introduction: In Primary Bilateral Macronodular Adrenal Hyperplasia (PBMAH), cortisol secretion may be consecutive to physiological stimuli, through the illegitimate expression of G-protein coupled receptors (GPCR) in adrenocortical cells. The most characterized is the overexpression of GIP receptor (GIPR) leading to food-dependent Cushing syndrome (FDCS) but it has not been associated with the consecutive inactivation of ARMC5 responsible for 25% of PBMAH. This work aimed to ...

Introduction: PBMAH is a rare but heterogeneous disease, characterized by multiple benign adrenal macronodules with variable levels of cortisol excess. In 2013, our team discovered germline heterozygous inactivating mutations of ARMC5, acting as a tumor suppressor gene. ARMC5 mutation rate is 50% in patients with PBMAH treated by adrenalectomy for severe hypercortisolism, 80% in familial cases and 20% in sporadic cases according to the current literature. The...
