Cortisone Reductase Deficiency 2 (CRD2) Overview

Cortisone reductase deficiency 2, also known as CRD2, is a rare genetic disorder characterized by the inability to convert cortisone into its active form, cortisol. This conversion is typically facilitated by the enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), which is responsible for reducing cortisone to cortisol.

Key Features of CRD2

• Failure to regenerate cortisol: The primary issue in CRD2 is the inability to convert cortisone into cortisol, leading to a deficiency in this essential glucocorticoid.
• Increased cortisone levels: As a result of the enzyme's dysfunction, cortisone levels remain elevated, while cortisol levels are decreased.
• Adrenal gland involvement: The disorder affects the adrenal glands' ability to produce cortisol, leading to an imbalance in steroid hormone production.

Causes and Genetics

CRD2 is caused by mutations in the HSD11B1 gene, which codes for the 11β-HSD1 enzyme. This genetic defect leads to a failure of the enzyme to function properly, resulting in the inability to convert cortisone into cortisol.

Cortisone reductase deficiency 2 (CORTRD2) is a rare genetic disorder characterized by the inability to convert cortisone to cortisol, leading to an excess of androgens in the body. The signs and symptoms of CORTRD2 can vary from person to person but may include:

• Hyperandrogenism: Excess androgen production can cause a range of symptoms, including:
  • Hirsutism (excessive hair growth on the face, chest, back, or buttocks) [1]
  • Acne [1]
  • Male pattern baldness in women [1]
• Recurrent infections: Individuals with CORTRD2 may be more susceptible to infections due to impaired cortisol production, which can affect the immune system [3].
• Skin coloring: Some people with CORTRD2 may have skin that is darker than average [4].
• Other features: In some cases, CORTRD2 may also cause other symptoms, such as:
  • Increased blood pressure
  • Changes in body shape or composition

It's essential to note that the severity and presentation of CORTRD2 can vary significantly among individuals. If you suspect you or a family member might be affected by this condition, consult with a qualified healthcare professional for proper evaluation and guidance.

Diagnostic Tests for Cortisone Reductase Deficiency 2

Cortisone reductase deficiency 2 (CRD2) is a rare genetic disorder that affects the conversion of cortisone to cortisol. Diagnosing CRD2 requires a combination of clinical evaluation, biochemical tests, and genetic analysis.

• Biochemical Tests: These include measuring the levels of cortisone and cortisol in the blood or urine. In individuals with CRD2, the ratio of cortisone to cortisol is typically elevated [1][3].
• Genetic Analysis: This involves sequencing the HSD11B1 gene, which encodes for the 11β-hydroxysteroid dehydrogenase type 1 enzyme (11β-HSD1). Mutations in this gene can lead to CRD2 [5][13].
• Clinical Evaluation: A thorough medical history and physical examination are essential to rule out other conditions that may present with similar symptoms.

Specific Diagnostic Tests

• Sequence Analysis of the HSD11B1 Gene: This is a genetic test that analyzes the entire coding region of the HSD11B1 gene [10].
• Bi-directional Sanger Sequence Analysis: This is another genetic test that examines the HSD11B1 gene for mutations [10].

Important Notes

• These diagnostic tests should only be performed by qualified healthcare professionals and in a clinical setting.
• A diagnosis of CRD2 should be made based on a combination of biochemical, genetic, and clinical findings.

Cortisone reductase deficiency 2, also known as apparent cortisone reductase deficiency (ACRD), is a rare endocrine disorder characterized by androgen excess in women or children and decreased urinary excretion of cortisol.

Treatment Options:

• Antiandrogens can be prescribed to treat hyperandrogenism associated with cortisone reductase deficiency 2 [2].
• However, it's essential to consult with a healthcare professional for medical advice and treatment, as they can provide personalized guidance on managing this condition [3].

Note: Cortisone reductase deficiency 2 is a rare disorder, and treatment options may vary depending on individual cases. Consultation with a qualified specialist is crucial for accurate diagnosis and effective management.

Cortisone reductase deficiency (CRD) is a rare genetic disorder characterized by the inability to convert cortisone to cortisol in the periphery, leading to increased cortisol production and androgen excess. When considering the differential diagnosis for CRD, several conditions should be taken into account.

• Polycystic Ovary Syndrome (PCOS): Women with PCOS may exhibit symptoms similar to those of CRD, including androgen excess and irregular menstrual cycles.
• Congenital Adrenal Hyperplasia (CAH): CAH is a group of genetic disorders that affect the adrenal glands, leading to an overproduction or underproduction of cortisol. The symptoms can be similar to those of CRD, but CAH typically presents with more severe androgen excess.
• 5-alpha-reductase deficiency: This is another rare genetic disorder that affects the conversion of testosterone to dihydrotestosterone (DHT), leading to androgen excess and ambiguous genitalia in males. However, 5-alpha-reductase deficiency typically presents with more pronounced virilization and does not involve cortisol metabolism.
• Cortisol reductase deficiency type 2: This is a rare cause of increased cortisol production due to the inability to convert cortisone to cortisol in the periphery.

It's essential to note that the differential diagnosis for CRD can be complex, and a comprehensive evaluation by an endocrinologist or geneticist may be necessary to determine the underlying cause of symptoms. A thorough medical history, physical examination, and laboratory tests, including steroid profile analysis, are typically required to differentiate between these conditions.

According to [5], 'Apparent' cortisone reductase deficiency (ACRD) is characterized by androgen excess in women or children and decreased urinary excretion of cortisol, which can be a clue for the differential diagnosis. Additionally, as mentioned in [8], steroid profile analysis of a 24-h urine collection provides a diagnostic method for discriminating between ACRD and CRD.
