Comparison
6q Terminal Deletion Syndrome C4304514 vs 2 3 Toe Cutaneous Syndactyly C0432040
Clinical comparison between 6Q Terminal Deletion Syndrome and 2 3 Toe Cutaneous Syndactyly for differential diagnosis and treatment planning.
6q Terminal Deletion Syndrome C4304514
A chromosomal disorder involving deletion of genetic material at the end of chromosome 6, leading to developmental delays and variable physical features.
2 3 Toe Cutaneous Syndactyly C0432040
A birth condition where the skin of the second and third toes is joined together. It may occur on its own or with other conditions. Surgery can separate the toes if needed.

Key differentiating points
Findings that most reliably separate the two conditions at the bedside or in the workup.
| Feature | 6q Terminal Deletion Syndrome C4304514 | 2 3 Toe Cutaneous Syndactyly C0432040 | Discriminating power |
|---|---|---|---|
| Development | Associated with developmental delay; features and severity vary and are not fully specified here. | Isolated toe webbing does not itself establish developmental delay. | High |
| Toe findings | Variable physical features may occur; specific toe involvement is not established by this source. | Skin joining of the second and third toes is the defining finding. | High |
| Extent | A chromosomal disorder that can affect development beyond one body region. | Often localized, but it may occur with other conditions. | Moderate |
When to favor each condition
Choose 6q Terminal Deletion Syndrome C4304514 when
Confirmed terminal 6q deletion
A genetic result supports the chromosomal diagnosis rather than an isolated toe finding.
High
Delay with congenital anomalies
A broader phenotype warrants genetics evaluation; appearance alone is insufficient.
Moderate
Counseling after genetic confirmation
The confirmed deletion frames developmental planning and recurrence discussion.
Moderate
Choose 2 3 Toe Cutaneous Syndactyly C0432040 when
Isolated 2–3 toe skin webbing
This matches cutaneous syndactyly when no broader condition is identified.
High
Concern limited to foot function or shoes
Care may involve observation or elective separation if clinically needed.
Moderate
Webbing plus other anomalies
Document the toe finding while evaluating possible associated conditions.
Moderate
How key tests differ
| Test | 6q Terminal Deletion Syndrome C4304514 | 2 3 Toe Cutaneous Syndactyly C0432040 | Interpretation |
|---|---|---|---|
| Chromosomal microarray or karyotype | May detect a terminal 6q deletion; specialist interpretation is required. | Often normal when truly isolated; consider testing if other features exist. | A deletion supports the left diagnosis; a normal result does not exclude every syndrome. |
| Foot examination | No specific toe abnormality is established by the supplied description. | Visible cutaneous bridge between the second and third toes. | Examination defines the right finding but cannot diagnose a chromosomal deletion. |
| Developmental assessment | Delay may be present, with variable and unquantified extent. | Not expected from isolated syndactyly alone. | Delay should prompt broader evaluation rather than attribution to toe webbing. |
Prognosis comparison
6q Terminal Deletion Syndrome C4304514
- Outcome
- A chronic congenital condition with variable developmental impact; exact outcomes are not established.
- Factors
- Deletion extent, associated anomalies, and available developmental support may influence course.
2 3 Toe Cutaneous Syndactyly C0432040
- Outcome
- Usually a mild chronic structural finding with limited impact when isolated.
- Factors
- Isolation, foot function, footwear, and whether surgery is needed influence impact.
Time frame: Both are present from birth; clinical needs may evolve through childhood.
Prognosis must be individualized; comparative mortality and prevalence are not established.
Complications comparison
| Complication | Presentation |
|---|---|
| Developmental needs | Possible and variable because of the chromosomal disorder. Not expected from isolated cutaneous syndactyly. Do not attribute developmental needs to toe webbing without evaluation. |
| Foot function | Specific functional complications are not established here. Mild shoe-fitting or functional difficulty may occur; many remain uncomplicated. Surgery is individualized and not universally required. |
| Associated conditions | Variable congenital features may coexist; a complete list is not established. May be isolated or accompany another condition. One finding should not automatically establish either diagnosis. |
Patient education highlights
- HighConfirming the diagnosis
Genetic testing confirms a 6q deletion, whereas toe webbing is a physical finding that may be isolated.
- HighWhen to seek review
Developmental concerns, additional congenital findings, or functional toe problems need clinician assessment.
- MediumTreatment expectations
No standard dose or surgery threshold is established here; separation is considered only if needed.
