We have previously described the only reported case of human proprotein convertase 1 (PC1) deficiency, in a female (Subject A) with obesity, hypogonadism, hypoadrenalism, and reactive hypoglycemia. We now report the second case of human PC1 deficiency (Subject B), also due to compound heterozygosity for novel missense and nonsense mutations. While both(More)
CONTEXT Missense loss-of-function mutations in TAC3 and TACR3, the genes encoding neurokinin B and its receptor NK3R, respectively, were recently discovered in kindreds with nonsyndromic normosmic congenital hypogonadotropic hypogonadism (CHH), thus identifying a fundamental role of this pathway in the human gonadotrope axis. OBJECTIVE The objective of(More)
OBJECTIVE Germline mutations of the aryl hydrocarbon receptor-interacting protein gene (AIP) have recently been described in three families with GH or prolactin-secreting tumors, as well as in a few patients with apparently sporadic somatotropinomas. The aim of the study was to determine the prevalence of AIP mutations in a large cohort of patients with(More)
OBJECTIVE DAX1/NR0B1 mutations cause primary adrenal insufficiency in early childhood and hypogonadotropic hypogonadism (HHG), leading to absent or incomplete sexual maturation. The aim of the study was to prospectively investigate gonadotrope and testicular functions in a patient carrying a DAX1 mutation, who had spontaneous puberty and normal virilization(More)
Heterozygous germline mutations in the gene encoding the aryl hydrocarbon receptor-interacting protein (AIP) were first described in two Finnish families with pituitary adenomas. The gene is involved in about 15% of familial isolated pituitary adenomas (FIPA), in about 50% of cases of familial acromegaly and in a small proportion of acromegalic patients(More)
CONTEXT Outcomes of congenital adrenal hyperplasia due to classic 21-hydroxylase deficiency (21OHD) have been widely studied in children and women, but less so in men. OBJECTIVE The objective was to analyze data from a network of metropolitan French teaching hospitals on the clinical outcome of classic 21OHD in a large sample of congenital adrenal(More)
BACKGROUND Carney complex (CNC) is an autosomal dominant multiple neoplasia, caused mostly by inactivating mutations of the regulatory subunit 1A of the protein kinase A (PRKAR1A). Primary pigmented nodular adrenocortical disease (PPNAD) is the most frequent endocrine manifestation of CNC with a great inter-individual variability. Germline,(More)
CONTEXT Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a rare cause of primary adrenal Cushing's syndrome (CS). ARMC5 germline mutations have been identified recently in PBMAH. OBJECTIVE To determine the prevalence of ARMC5 mutations and analyze genotype-phenotype correlation in a large cohort of unrelated PBMAH patients with subclinical or(More)
Adrenal tumors occur more frequently in women and are the leading cause of Cushing's syndrome during pregnancy. We aimed to evaluate the potential role of sex steroids in the susceptibility of women to adrenocortical tumors. We evaluated the presence of the progesterone receptor (PR), estradiol receptors (ERs), and aromatase in 5 patients with primary(More)
The proprotein convertase PC2 is primarily expressed in neuroendocrine cells where it mediates the proteolytic maturation of prohormones and proneuropeptides. We have identified in the upstream sequence of its gene a conserved domain partially homologous to the repressor element RE1/NRSE found in several genes for neuronal proteins. RE1/NRSE binds the(More)
