Affected males may also have a shortage of male sex hormones, which leads to underdeveloped reproductive tissues, undescended testicles, delayed puberty, and an inability to father children. Together, these characteristics are known as hypogonadotropic hypogonadism.
The onset and severity of these signs and symptoms can vary, even among affected members of the same family.
The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
|Signs and Symptoms||Approximate number of patients (when available)|
|Absence of pubertal development||-|
|Autosomal recessive inheritance||-|
|Decreased circulating aldosterone level||-|
|Decreased circulating cortisol level||-|
|Failure to thrive||-|
|Hyperpigmentation of the skin||-|
|Renal salt wasting||-|
|X-linked recessive inheritance||-|
Some NR0B1 mutations result in the production of an inactive version of the DAX1 protein, while other mutations delete the entire gene. The resulting shortage of DAX1 disrupts the normal development and function of hormone-producing tissues in the body. The signs and symptoms of adrenal insufficiency and hypogonadotropic hypogonadism occur when endocrine glands do not produce the right amounts of certain hormones.
In X-linked recessive inheritance, a female with one mutated copy of the gene in each cell is called a carrier. She can pass on the altered gene, but usually does not experience signs and symptoms of the disorder. In rare cases, however, females who carry a NR0B1 mutation may experience adrenal insufficiency or signs of hypogonadotropic hypogonadism such as underdeveloped reproductive tissues, delayed puberty, and an absence of menstruation.

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Nonprofit support and advocacy groups bring together patients, families, medical professionals, and researchers. These groups often raise awareness, provide support, and develop patient-centered information. Many are the driving force behind research for better treatments and possible cures. They can direct people to research, resources, and services. Many groups also have experts who serve as medical advisors. Visit their website or contact them to learn about the services they offer.

International Adrenal Cortex Conference “Adrenal 2010”
Wednesday, June 16, 2010 -
Friday, June 18, 2010
Location: San Diego, California
Description: This conference provided a forum for both new and established investigators to present their most recent work, highlighting new findings relevant to adrenal physiology, biochemistry and molecular biology, genetics, and medicine. It was anticipated that these discoveries would provide a framework for further understanding of the function of the adrenal gland and its contributions to health and disease.
