Summary Summary

3-beta-hydroxysteroid dehydrogenase (3BHSD) deficiency is a form of congenital adrenal hyperplasia, a group of conditions that interfere with the body's ability to make hormones. People with this condition lack many of the hormones made in the gonads (testes or ovaries) and the adrenal glands. There are three types of 3BHSD deficiency - the salt-wasting form, non-salt-wasting form, and non-classic form. Signs and symptoms depend on the type of 3BHSD deficiency; the age at diagnosis; and the sex of the affected person. The salt-wasting form is the most severe type and can even be life-threatening. People with this form are generally diagnosed at birth due to symptoms related to abnormal salt reabsorption (i.e. dehydration, poor feeding, vomiting). Males with any form of the condition often have abnormalities of the external genitalia and are frequently infertile. Females with the condition may have slight genital abnormalities at birth, but often go on to experience irregular menstruation, hirsutism, and infertility as they get older. 3BHSD deficiency is caused by changes (mutations) in the HSD3B2 gene and is inherited in an autosomal recessive manner. Treatment varies but may include medications and/or surgery.^[1]^[2]

Diagnosis Diagnosis

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

Testing Resources

The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

Treatment Treatment

People with the salt-wasting form of 3-beta–hydroxysteroid dehydrogenase (3BHSD) deficiency need replacement of glucocorticoids, mineralocorticoids, and sex steroids. This may include:

Oral hydrocortisone (or other glucocorticoid) - hydrocortisone tablets are the preferred choice for treatment. In children, premixed, oral suspensions of hydrocortisone and long-acting glucocorticoid preparations should be avoided.
Mineralocorticoid replacement by oral fludrocortisone acetate - those with non–salt-losing forms do not need mineralocorticoid replacement.
Sex steroid replacement at puberty for those with a complete deficiency - including testosterone in males and cyclic estrogen-progesterone therapy in females. This promotes development of secondary sexual characteristics in both males and females, and cyclic menstrual bleeding in females with normal female chromosomes.

In people with late-onset (non-classic) 3BHSD deficiency, the need for replacement therapy varies depending on the severity of the condition. Glucocorticoid replacement suppresses excess male hormones (androgens) in children with premature onset of puberty. In pubertal and post-pubertal females with the late-onset form, glucocorticoid replacement alone may correct menstrual irregularities and infertility, and decrease hirsutism and acne.^[3]

Last updated: 2/22/2016

Prognosis Prognosis

The long-term outlook (prognosis) for people with 3BHSD deficiency is usually good-to-excellent with adequate replacement glucocorticoid and mineralocorticoid therapy (if needed) and monitoring.^[3]

Because the enzyme deficiency is inherited and caused by genetic mutations present from birth, the condition will inherently be present (i.e. enzyme production will not increase during an affected person's lifetime).

Males with poorly-controlled congenital adrenal hyperplasia (CAH) are at risk for benign testicular adrenal rest tumors.^[3]

I am a 24-year-old female and I was diagnosed with HSD3B deficiency about 5 years ago. I was prescribed heavy contraceptive pills (essentially hormones) but, so far, I have refused to take them because of associated side effects. What do you advise for HSD3B deficiency management? Are there cases of people that have started producing the enzyme later on in their lives? What research is out there that I could get my hands on? See answer
