Comparison
6q Terminal Deletion Syndrome C4304514 vs 2 4 Finger Cutaneous Syndactyly C4021236
Clinical comparison between 6Q Terminal Deletion Syndrome and 2 4 Finger 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 4 Finger Cutaneous Syndactyly C4021236
A birth defect where the skin between the second and fourth fingers is webbed together. This mild hand difference may be corrected with surgery to improve function and appearance.

Bottom line
6q-terminal-deletion-syndrome-C4304514 and 2-4-finger-cutaneous-syndactyly-C4021236 differ in severity, etiology
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 4 Finger Cutaneous Syndactyly C4021236 | Discriminating power |
|---|---|---|---|
| Development | Developmental delay is described, but its extent varies and is not fully defined. | Isolated finger webbing does not by itself imply developmental delay. | High |
| Hand appearance | Physical features may vary; a specific 2–4 finger pattern is not established. | Skin webbing between the second and fourth fingers is the defining finding. | High |
| Overall extent | Classified as severe and potentially broader than one body region. | Classified as mild and mainly a localized hand difference. | Moderate |
When to favor each condition
Choose 6q Terminal Deletion Syndrome C4304514 when
Developmental delay with congenital anomalies
A chromosomal explanation is more relevant than an isolated hand finding.
Moderate
Confirmed terminal loss of chromosome 6 material
The syndrome label depends on documented chromosomal deletion.
High
Multisystem congenital presentation
Broader genetic assessment fits better than a localized syndactyly description.
Moderate
Choose 2 4 Finger Cutaneous Syndactyly C4021236 when
Isolated webbing of fingers 2–4
The visible finding matches cutaneous syndactyly without syndrome evidence here.
High
Concern limited to hand function or appearance
Hand-focused assessment is appropriate; surgery may be discussed individually.
Moderate
No documented developmental concerns
A localized musculoskeletal description is preferable pending clinician review.
Moderate
How key tests differ
| Test | 6q Terminal Deletion Syndrome C4304514 | 2 4 Finger Cutaneous Syndactyly C4021236 | Interpretation |
|---|---|---|---|
| Chromosomal microarray or karyotype | May identify a terminal chromosome 6 deletion; breakpoints are not supplied. | Not expected to explain isolated cutaneous webbing. | A confirmed deletion supports the left concept; a normal result does not exclude every syndrome. |
| Clinical hand examination | Variable anomalies are possible, but no specific pattern is established. | Webbed skin between the second and fourth fingers is expected. | Examination identifies the hand finding but cannot diagnose a chromosomal disorder. |
| Developmental assessment | Delays may be found, with individual severity. | Not indicated by the hand finding alone. | Abnormal development warrants broader evaluation rather than syndactyly labeling alone. |
Prognosis comparison
6q Terminal Deletion Syndrome C4304514
- Outcome
- Long-term outcome varies and is not quantified in the supplied data.
- Factors
- Deletion extent, associated anomalies, and developmental support; exact effects are unestablished.
2 4 Finger Cutaneous Syndactyly C4021236
- Outcome
- Often a mild hand difference, but individual function and appearance vary.
- Factors
- Webbing extent, hand function, surgical candidacy, and healing; success rates are not supplied.
Time frame: Both are congenital and may have lasting implications; precise timelines are not established.
Associated findings, clinician assessment, and supportive care matter more than either label alone.
Complications comparison
| Complication | Presentation |
|---|---|
| Developmental impairment | Delay is described, but specific outcomes are not established. Not an expected result of isolated skin webbing. Cognitive outcome should not be inferred from either label alone. |
| Hand-function limitation | Possible only if relevant limb anomalies are present; none are specified. Webbing may affect finger separation, grasp, or appearance. Function should be assessed individually; surgical benefit is not quantified here. |
| Ongoing specialist care | Genetics and developmental follow-up are often relevant. Hand surgery or therapy may be considered. Care needs differ and require clinician judgment. |
Patient education highlights
- HighDifferent conditions
One is a chromosomal disorder; the other is a localized finger-skin difference. A clinician must confirm which applies.
- HighResults need interpretation
Genetic or hand findings require specialist review. An abnormal result is not automatically a complete diagnosis.
- MediumIndividualized care
Syndactyly may be considered for surgery. No timing, technique, dose, or guaranteed outcome is established here.
