Comparison
46 Xy Disorder Of Sex Development Due To Testicular 17 20 Desmolase Deficiency C1839840 vs Abducens Nerve Disorder C0271355
Clinical comparison between 46 XY Disorder OF Sex Development Due TO Testicular 17 20 Desmolase Deficiency and Abducens Nerve Disorder for differential diagnosis and treatment planning.
46 Xy Disorder Of Sex Development Due To Testicular 17 20 Desmolase Deficiency C1839840
A rare genetic condition where the testes cannot make enough testosterone due to an enzyme deficiency. This affects genital development and puberty. Treatment includes hormone therapy and may involve surgery.
Abducens Nerve Disorder C0271355
An abducens nerve disorder affects the sixth cranial nerve, which controls side-to-side eye movement. It can impact individuals of any age and results in difficulty moving the eye outward. Treatment depends on the underlying cause and may include medication or surgery.

Key differentiating points
Findings that most reliably separate the two conditions at the bedside or in the workup.
| Feature | 46 Xy Disorder Of Sex Development Due To Testicular 17 20 Desmolase Deficiency C1839840 | Abducens Nerve Disorder C0271355 | Discriminating power |
|---|---|---|---|
| Genital or pubertal development | Atypical genital development or delayed puberty may occur from insufficient testicular testosterone. | No primary effect on genital development or puberty is described. | High |
| Eye movement | Outward eye-movement limitation is not a feature of this enzyme deficiency. | Difficulty moving one or both eyes outward may occur. | High |
| System involved | Primarily reproductive and endocrine development. | Primarily neurologic control of lateral eye movement. | High |
When to favor each condition
Choose 46 Xy Disorder Of Sex Development Due To Testicular 17 20 Desmolase Deficiency C1839840 when
Atypical genital development in a 46,XY infant or child
The source links this condition to impaired testicular testosterone production and genital development.
Moderate
Absent or incomplete puberty with a suspected genetic enzyme deficiency
Pubertal effects are described, but the exact cause requires specialist confirmation.
Moderate
Endocrine evaluation suggests a testicular steroidogenic defect
The named enzyme deficiency is an endocrine diagnosis, not an eye-movement disorder.
High
Choose Abducens Nerve Disorder C0271355 when
New or persistent inability to move an eye outward
This matches the described function of the abducens nerve.
High
Double vision or eye misalignment without genital or pubertal findings
The source localizes the disorder to cranial-nerve control of eye movement.
Moderate
A neurologic cause is being investigated at any age
Onset is variable and treatment depends on the underlying cause.
Moderate
How key tests differ
| Test | 46 Xy Disorder Of Sex Development Due To Testicular 17 20 Desmolase Deficiency C1839840 | Abducens Nerve Disorder C0271355 | Interpretation |
|---|---|---|---|
| Chromosomal and endocrine evaluation | May support a 46,XY disorder with impaired testosterone production; exact cutoffs are not supplied. | Not expected to diagnose an abducens nerve disorder. | Abnormal hormone results are not themselves a complete diagnosis and need clinician interpretation. |
| Eye-movement and neurologic examination | No characteristic eye-movement abnormality is described. | May show impaired abduction and related alignment findings. | Examination localizes the problem but does not establish its cause. |
| Imaging or cause-directed testing | Genetic or endocrine testing may be considered by specialists. | Testing is directed by the suspected neurologic cause. | Neither condition has one universally required test in the supplied data. |
Prognosis comparison
46 Xy Disorder Of Sex Development Due To Testicular 17 20 Desmolase Deficiency C1839840
- Outcome
- A chronic developmental condition; specific survival or recovery figures are not established here.
- Factors
- Timing of recognition, hormone findings, and individualized specialist care may influence management.
Abducens Nerve Disorder C0271355
- Outcome
- Course varies with the underlying neurologic cause; recovery rates are not supplied.
- Factors
- Cause, duration, and response to cause-directed care may influence outcome.
Time frame: Left onset is described from birth through adolescence; right onset is variable. Both may be chronic.
Prognosis should be interpreted by clinicians because comparative outcome data are not provided.
Complications comparison
| Complication | Presentation |
|---|---|
| Developmental effects | Genital development and puberty may be affected. Eye alignment and binocular vision may be affected. Complications follow the involved system and are not interchangeable. |
| Functional limitation | Hormone-related development may require long-term specialist care. Outward gaze limitation may impair visual function. Severity is described as severe on the left and moderate on the right, without outcome rates. |
| Treatment-related considerations | Hormone therapy and sometimes surgery may be considered. Medication or surgery may be used depending on cause. No doses, procedures, or outcome guarantees are established here. |
Patient education highlights
- HighDifferent conditions
One affects sex development through an enzyme deficiency; the other affects side-to-side eye movement.
- HighSpecialist care
Endocrine or genetics specialists and neurology or ophthalmology specialists address different problems.
- MediumCause matters
An abnormal finding or suspected diagnosis should be confirmed before treatment decisions.
