Comparison
5p Partial Monosomy Syndrome C0010314 vs 2 Hydroxyglutaric Aciduria C2746066
Clinical comparison between 5P Partial Monosomy Syndrome and 2 Hydroxyglutaric Aciduria for differential diagnosis and treatment planning.
5p Partial Monosomy Syndrome C0010314
Also called Cri-du-chat syndrome, caused by a deletion on chromosome 5. Features include a high-pitched cry, developmental delay, and intellectual disability.
2 Hydroxyglutaric Aciduria C2746066
An organic acidemia where elevated acids accumulate in the body. It can cause neurological and developmental problems. Treatment focuses on supportive care and symptom management.

Bottom line
5p-partial-monosomy-syndrome-C0010314 and 2-hydroxyglutaric-aciduria-C2746066 differ in severity, etiology
Key differentiating points
Findings that most reliably separate the two conditions at the bedside or in the workup.
| Feature | 5p Partial Monosomy Syndrome C0010314 | 2 Hydroxyglutaric Aciduria C2746066 | Discriminating power |
|---|---|---|---|
| High-pitched cry | Characteristic neonatal cry may be present. | Not a described feature. | High |
| Developmental delay | Common, often with intellectual disability. | Neurological and developmental problems may occur. | Low |
| Metabolic signs | No characteristic organic-acid accumulation described. | Elevated organic acids may accumulate. | Moderate |
When to favor each condition
Choose 5p Partial Monosomy Syndrome C0010314 when
Newborn with distinctive cry and congenital features
Supports chromosomal evaluation for a 5p deletion.
Moderate
Suspected genetic syndrome from birth
Onset is congenital rather than later childhood.
Moderate
Need to distinguish etiology
A chromosomal deletion differs from an organic acidemia.
High
Choose 2 Hydroxyglutaric Aciduria C2746066 when
Neurological symptoms with suspected metabolic disease
Organic-acid testing may be appropriate.
Moderate
Childhood-onset developmental concerns
Reported onset can extend through childhood.
Low
Abnormal organic-acid result
An abnormal result is not itself a diagnosis and needs confirmation.
High
How key tests differ
| Test | 5p Partial Monosomy Syndrome C0010314 | 2 Hydroxyglutaric Aciduria C2746066 | Interpretation |
|---|---|---|---|
| Karyotype or chromosomal microarray | May show deletion involving chromosome 5p. | Not expected to establish this metabolic disorder. | A confirmed deletion supports the chromosomal diagnosis. |
| Urine organic acids | No characteristic elevation is established. | May show elevated 2-hydroxyglutaric acid; no cutoff is supplied. | An abnormal result requires specialist confirmation. |
| Genetic or metabolic specialist assessment | Focuses on chromosomal findings and development. | Focuses on metabolic results and neurological course. | Testing choice depends on clinical context. |
Prognosis comparison
5p Partial Monosomy Syndrome C0010314
- Outcome
- Chronic congenital condition, often severe, with developmental disability.
- Factors
- Deletion findings, developmental course, and associated congenital issues.
2 Hydroxyglutaric Aciduria C2746066
- Outcome
- Chronic metabolic disorder with variable neurological effects; exact prognosis is not established.
- Factors
- Metabolic subtype, neurological involvement, and response to supportive care.
Time frame: Lifelong for both; onset is typically neonatal on the left and infancy to childhood on the right.
No mortality or treatment-dose conclusions can be drawn from the supplied data.
Complications comparison
| Complication | Presentation |
|---|---|
| Intellectual disability | A recognized feature. Developmental impairment may occur. Severity varies and is not predictable from these data. |
| Neurological problems | Developmental effects are expected. Neurological problems are described. Specific complications are not established here. |
| Long-term care needs | Often substantial because severity is listed as severe. Supportive care is central; listed severity is moderate. Individual needs require clinical assessment. |
Patient education highlights
- HighDifferent causes
One is a chromosome deletion; the other is a metabolic acid accumulation disorder.
- HighTesting limits
An abnormal laboratory result is not automatically a confirmed diagnosis.
- MediumCare planning
Both are chronic and generally managed with supportive, individualized care.
