Comparison
46 Xy Disorder Of Sex Development Due To Isolated 17 20 Lyase Deficiency C5681470 vs Abducens Nerve Palsy C4551519
Clinical comparison between 46 XY Disorder OF Sex Development Due TO Isolated 17 20 Lyase Deficiency and Abducens Nerve Palsy 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 Palsy C4551519
Abducens nerve palsy is weakness or paralysis of the nerve controlling outward eye movement. It can affect anyone and typically causes double vision or difficulty looking sideways. Management focuses on treating the root cause and may involve eye patches 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 Palsy C4551519 | Discriminating power |
|---|---|---|---|
| Genital development | Undervirilization may be present from birth in 46,XY individuals. | No primary effect on genital development is described. | High |
| Eye movement | No characteristic ocular-movement abnormality is established. | Weakness or paralysis of outward gaze, often with double vision. | High |
| Course | Described as a chronic endocrine condition. | Often acute, with variable onset and cause. | Moderate |
When to favor each condition
Choose 46 Xy Disorder Of Sex Development Due To Isolated 17 20 Lyase Deficiency C5681470 when
46,XY undervirilization
Isolated 17,20-lyase deficiency is considered when androgen synthesis is suspected.
Moderate
Endocrine specialist evaluation
Hormone assessment and clinician interpretation are needed; a result alone is not a diagnosis.
High
Long-term hormone planning
Management may include hormone therapy, individualized by a clinician.
Moderate
Choose Abducens Nerve Palsy C4551519 when
New double vision
Abducens palsy is considered when lateral gaze is weak or painful symptoms suggest a neurologic cause.
Moderate
Difficulty looking sideways
The supplied description centers on impaired outward eye movement.
High
Acute neurologic presentation
Urgent clinician assessment is appropriate because causes vary and may be serious.
High
How key tests differ
| Test | 46 Xy Disorder Of Sex Development Due To Isolated 17 20 Lyase Deficiency C5681470 | Abducens Nerve Palsy C4551519 | Interpretation |
|---|---|---|---|
| Hormone profile | Androgen-pathway abnormalities may be sought; exact cutoffs are not supplied. | No characteristic hormone abnormality is established. | Abnormal results require specialist interpretation and do not alone confirm the diagnosis. |
| Eye examination | No specific ocular finding is established. | Impaired abduction and diplopia may be found. | Clinical eye findings support the neurologic description but not its cause. |
| Cause-directed imaging | Not established as a primary test from the supplied data. | Imaging or other evaluation may be used to investigate the root cause. | Choice and interpretation depend on clinical context. |
Prognosis comparison
46 Xy Disorder Of Sex Development Due To Isolated 17 20 Lyase Deficiency C5681470
- Outcome
- A chronic condition; outcome data are not supplied.
- Factors
- Hormone management and individual development may influence care needs.
Abducens Nerve Palsy C4551519
- Outcome
- Variable and cause-dependent; recovery is not guaranteed.
- Factors
- Root cause, duration, and response to cause-directed care.
Time frame: Congenital and chronic versus often acute but variable.
No comparative mortality or recovery rates are established.
Complications comparison
| Complication | Presentation |
|---|---|
| Undervirilization-related effects | Possible developmental and hormonal consequences; specifics are not established here. Not a described feature. Counseling and management should be individualized. |
| Diplopia | Not established. Double vision may impair visual function. Safety risks such as falls should be assessed clinically. |
| Underlying-cause complications | The supplied source does not establish additional complications. Complications depend on the cause and are not uniform. Do not infer prognosis from the palsy alone. |
Patient education highlights
- HighDifferent conditions
These conditions affect different systems and are not alternative labels for one disease.
- HighUrgent eye symptoms
Sudden double vision or gaze weakness needs prompt clinical assessment.
- MediumSpecialist care
Endocrine or neurologic referral and interpretation of tests should guide decisions.
