Comparison
46 Xy Disorder Of Sex Development Due To Isolated 17 20 Lyase Deficiency C5681470 vs Abducens Nerve Disorder C0271355
Clinical comparison between 46 XY Disorder OF Sex Development Due TO Isolated 17 20 Lyase Deficiency and Abducens Nerve Disorder for differential diagnosis and treatment planning.
46 Xy Disorder Of Sex Development Due To Isolated 17 20 Lyase Deficiency C5681470
A rare condition involving deficiency of the 17,20-lyase enzyme needed for androgen synthesis. Affects 46,XY individuals and causes undervirilization. Managed with hormone therapy.
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 Isolated 17 20 Lyase Deficiency C5681470 | Abducens Nerve Disorder C0271355 | Discriminating power |
|---|---|---|---|
| Genital development | Undervirilization may be present from birth | No primary genital abnormality is expected | High |
| Eye movement | Outward gaze is not primarily affected | Difficulty moving one or both eyes outward may occur | High |
| System involved | Reproductive and endocrine features predominate | Neurologic and ocular features predominate | High |
When to favor each condition
Choose 46 Xy Disorder Of Sex Development Due To Isolated 17 20 Lyase Deficiency C5681470 when
46,XY infant with undervirilization
The supplied description links this pattern to impaired androgen synthesis
Moderate
Suspected isolated enzyme deficiency
Endocrine evaluation is more relevant than eye-movement testing
Moderate
Need for hormone-management planning
Management is described as hormone therapy, individualized by specialists
Low
Choose Abducens Nerve Disorder C0271355 when
Impaired outward eye movement
This matches the described sixth-nerve function
High
New diplopia or ocular misalignment
Neurologic assessment is appropriate; cause is not established here
Moderate
Any age with acquired eye-movement change
The source states onset can occur at any age and is variable
Moderate
How key tests differ
| Test | 46 Xy Disorder Of Sex Development Due To Isolated 17 20 Lyase Deficiency C5681470 | Abducens Nerve Disorder C0271355 | Interpretation |
|---|---|---|---|
| Endocrine evaluation | May support impaired androgen synthesis | Not expected to explain the primary disorder | Abnormal results require specialist interpretation and do not alone confirm the diagnosis |
| Eye-movement examination | No characteristic finding is established | May show limited abduction | A finding suggests abducens dysfunction but not its cause |
| Neuroimaging or cause-directed testing | Not central to the described condition | May be used to investigate an underlying cause | Selection depends on clinical context; no universal result is established |
Prognosis comparison
46 Xy Disorder Of Sex Development Due To Isolated 17 20 Lyase Deficiency C5681470
- Outcome
- Chronic endocrine condition; long-term outcome is not established here
- Factors
- Diagnosis timing, hormone management, and individual development
Abducens Nerve Disorder C0271355
- Outcome
- Variable course depending on the underlying cause
- Factors
- Cause, duration, and response to cause-directed care
Time frame: Both may be chronic, but timing is not uniformly established
Accurate diagnosis and management of the underlying process
Complications comparison
| Complication | Presentation |
|---|---|
| Developmental effects | May involve atypical genital development Not a described feature Exact manifestations vary and should not be assumed |
| Visual function | No primary visual complication is established Double vision or impaired lateral gaze may occur Severity and persistence depend on cause |
| Treatment-related issues | Hormone therapy requires monitoring Medication or surgery may be considered Specific doses, procedures, and risks are not established here |
Patient education highlights
- HighDifferent conditions
One affects sex-hormone synthesis; the other affects eye movement. They are not interchangeable diagnoses.
- HighSpecialist care
Endocrine or neurologic evaluation should guide testing and treatment decisions.
- MediumUncertainty
Cause, course, and outcomes vary; avoid relying on a single abnormal finding.
