Comparison
21 Hydroxylase Deficient Congenital Adrenal Hyperplasia C2936858 vs 17q12 Recurrent Deletion Syndrome C6011081
Clinical comparison between 21 Hydroxylase Deficient Congenital Adrenal Hyperplasia and 17q12 Recurrent Deletion Syndrome for differential diagnosis and treatment planning.
21 Hydroxylase Deficient Congenital Adrenal Hyperplasia C2936858
An inherited disorder affecting adrenal hormone production, causing cortisol deficiency and other hormonal imbalances. Features may include ambiguous genitalia, salt-wasting crises, and growth issues. Treated with lifelong hormone replacement therapy.
17q12 Recurrent Deletion Syndrome C6011081
A genetic condition from deletion on chromosome 17. Can involve developmental delays, neurological features, and potential kidney involvement. Management requires regular monitoring and supportive therapies.

Key differentiating points
Findings that most reliably separate the two conditions at the bedside or in the workup.
| Feature | 21 Hydroxylase Deficient Congenital Adrenal Hyperplasia C2936858 | 17q12 Recurrent Deletion Syndrome C6011081 | Discriminating power |
|---|---|---|---|
| Acute hormonal imbalance | May cause cortisol deficiency and salt-wasting crisis. | Not primarily an adrenal steroid disorder. | High |
| Developmental or genital features | Ambiguous genitalia and growth issues may occur. | Developmental delay and neurologic features may occur. | Moderate |
| Kidney involvement | Kidney disease is not a core described feature. | Potential kidney involvement may occur. | Moderate |
When to favor each condition
Choose 21 Hydroxylase Deficient Congenital Adrenal Hyperplasia C2936858 when
Suspected adrenal or salt-wasting crisis
The described endocrine mechanism and severe course fit better.
High
Ambiguous genitalia with hormonal imbalance
This pattern is described for 21-hydroxylase-deficient CAH.
Moderate
Abnormal adrenal steroid testing
Results may support CAH but do not alone confirm it.
Moderate
Choose 17q12 Recurrent Deletion Syndrome C6011081 when
Developmental delay with congenital features
A chromosomal deletion syndrome is more consistent.
Moderate
Neurodevelopmental concerns plus kidney findings
Both features are described for 17q12 deletion.
Moderate
Detected recurrent 17q12 deletion
Genetic confirmation directly supports this diagnosis.
High
How key tests differ
| Test | 21 Hydroxylase Deficient Congenital Adrenal Hyperplasia C2936858 | 17q12 Recurrent Deletion Syndrome C6011081 | Interpretation |
|---|---|---|---|
| 17-hydroxyprogesterone | Often elevated; no cutoff is supplied. | No characteristic adrenal enzyme abnormality is described. | An abnormal result needs endocrine confirmation, not diagnosis alone. |
| Serum electrolytes | Salt-wasting may cause sodium and potassium abnormalities. | Electrolyte crisis is not a described core feature. | Abnormalities are urgent findings but not specific diagnoses. |
| Chromosomal microarray | Does not establish this adrenal enzyme disorder. | May detect the recurrent 17q12 deletion. | Genetic results require clinical correlation and counseling. |
Prognosis comparison
21 Hydroxylase Deficient Congenital Adrenal Hyperplasia C2936858
- Outcome
- Chronic and potentially severe, with outcomes influenced by crisis prevention and treatment.
- Factors
- Salt-wasting, early recognition, and adherence to replacement therapy.
17q12 Recurrent Deletion Syndrome C6011081
- Outcome
- Chronic and generally moderate, with variable developmental and renal effects.
- Factors
- Extent of features, kidney involvement, and support needs.
Time frame: Both are chronic; supplied onset data are incomplete.
Associated features, specialist follow-up, and individual response; exact prognosis is not established.
Complications comparison
| Complication | Presentation |
|---|---|
| Adrenal crisis | A potentially severe complication of cortisol deficiency. Not a typical described complication. Exact frequency and mortality are not established here. |
| Growth or development problems | Growth issues may occur. Developmental delay may occur. Severity and course vary and need clinician assessment. |
| Kidney complications | Not described as a core feature. Potential kidney involvement may require monitoring. Imaging or laboratory abnormalities are not diagnoses by themselves. |
Patient education highlights
- HighEmergency symptoms
CAH families should seek urgent care for vomiting, dehydration, lethargy, or suspected crisis.
- MediumDifferent genetic mechanisms
One is an adrenal enzyme disorder; the other is a chromosomal deletion. Neither is communicable.
- MediumFollow-up needs
CAH may need lifelong hormone replacement; 17q12 deletion may need developmental and kidney monitoring.
